1. METHODS OF MEASUREMEMT U.K.

1.1. Interference reflections during the photometric measurements must be avoided by means of appropriate masking. U.K.

1.2. Should the results of the measurements be contested, they must be carried out in such a way that: U.K.

1.2.1. the measuring distance is such that the inverse square law of the distance applies; U.K.

1.2.2. the measuring apparatus is such that the angular aperture of the receiver viewed from the centre of reference of the lamp lies between ten minutes of an angle and one degree; U.K.

1.2.3. the intensity requirement for a given direction of observation is satisfactory provided that requirement is met in a direction not diverging by more than a quarter of a degree from the direction of observation. U.K.

2. STANDARDIZED TABLE SHOWING SPATIAL DISTRIBUTION OF LIGHT U.K.

2.1. Direction H = 0^o and V = 0^o corresponds to the axis of reference (on the vehicle it is horizontal and parallel to the median longitudinal plane of the vehicle and pointing towards the required field of view). It passes through the centre of reference. The values set out in the table give the minimum intensities for the various directions of measurement as a percentage of the minimum required for each lamp within the axis (in direction H = 0^o and V = 0^o). U.K.

2.2. Within the field of light distribution represented in diagrammatic form in section 2 by a grid, the distribution of the light must essentially be uniform in such a way that the light intensity in each direction of a part of the field formed by the lines of the grid reaches at least the lowest minimum value specified as a percentage (or the lowest available value) on the lines of the grid which surround the direction at issue. U.K.

3. PHOTOMETRIC MEASUREMENT OF LAMPS EQUIPPED WITH SEVERAL LIGHT SOURCES U.K.

The photometric performance must be checked:

3.1. For non-replaceable (fixed) filament lamps or other light sources: U.K.

at the voltage prescribed by the manufacturer; the technical service may require from the manufacturer the special power supply needed to supply such lamps.

3.2. For replaceable filament lamps: U.K.

when equipped with mass-production filament lamps at 6,75 V, 13,5 V or 28,0 V the luminous intensity values produced must lie between the maximum limit and the minimum limit given in this Annex increased in accordance with the permissible deviation of the luminous flux permitted for the type of filament lamp chosen, as stated in Annex IV for production filament lamps; alternatively a standard filament lamp may be used in turn, in each of the inidvidual positions, operated at its reference flux, the individual measurements in each position being added.

2. COLOUR OF LIGHT EMITTED U.K.

The colour of the light emitted by the lamp used in the device must be white, but sufficiently neutral so as not to cause any appreciable change in the colour of the registration plate.

3. LIGHT INDICENCE U.K.

The manufacturer of the illuminating device must lay down the conditions for the fitting of the device in relation to the position intended for the registration plate. That device must occupy a position such that at none of the points on the surface to be illuminated with the angle of incidence of the light on the surface of the plate exceed 82^o, that angle being measured in relation to the extremity of the light-emitting surface of the device that is furthest from the surface of the plate. Where there is more than one optical component this requirement applies only to the part of the plate intended to be illuminated by the relevant component.

The device must be designed in such a manner that no ray of light shines directly towards the rear with the exception of rays of red light where the device is combined or grouped with a rear lamp.

4. METHOD OF MEASUREMENT U.K.

The levels of luminance are measured on a sheet of clean white blotting paper having a minimum factor of diffuse reflection of 70 % and the same dimensions as the registration plate and placed at the position it would normally occupy but 2 mm in front of its support.

The level of luminance is measured at right angles to the surface of the paper at the points shown in the diagram in section 5 below, each point representing a circular area 25 mm in diameter.

5. PHOTOMETRIC CHARACTERISTICS U.K.

Luminance B must be at least 2 cd/m² at each of the measuring points defined below.

The luminance gradient between values B

HEADLAMPS FOR MOTORCYCLES AND TRICYCLES EMITTING AN ASYMMETRICAL PASSING BEAM AND A DRIVING BEAM AND FITTED WITH HALOGEN FILAMENT LAMPS (HS₁ LAMPS) OR FILAMENT LAMPS OF CATEGORY R₂

1. ADDITIONAL REQUIREMENTS CONCERNING MARKS AND THE MARKING OF DEVICES U.K.

1.1. Headlamps designed in such a way as to meet the requirement of a single rule of the road (driving on either the right or the left) must, on the lens, bear the limits of the area which may possibly be masked in order to avoid distracting road users in a country where the rule of the road is not that for which the headlamp has been designed. However, when that area is directly identifiable by design any such delimitation is not necessary. U.K.

1.2. Headlamps designed in such a way as to meet the requirements of driving on the right and those for driving on the left must bear markings in order to locate the two positions for the fixing in position of the light unit on the vehicle or the lamp on the reflector; these markings consist of the letters ‘R/D’ for the position corresponding to driving on the right and the letters ‘L/G’ for the position corresponding to driving on the left. U.K.

1.3. All headlamps designed in such a way as to preclude any simultaneous lighting-up of the dipped-beam filament and that of any other light source with which they may be associated must be marked with an oblique stroke (/) within the component type-approval mark, after the passing beam headlamp symbol. U.K.

1.4. Where headlamps meet only the requirements of driving on the left, a horizontal arrow pointing to the right of an observer looking at the headlamp head on, i.e. towards the side of the road driven upon, must be entered below the component type-approval mark. U.K.

1.5. Where, by means of a deliberate alteration in the adjustment of the light unit or lamp, headlamps meet the requirements of both rules of the road, a horizontal arrow having two tips pointing one to the left and the other to the right must be entered below the component type-approval mark. U.K.

1.6. The letters ‘MBH’ on headlamps with HS₁ lamps are placed opposite the component type-approval mark. U.K.

1.7. The marks and symbols referred to above must be clearly visible and indelible. U.K.

2. GENERAL REQUIREMENTS U.K.

2.1. Each of the samples must meet the specifications set out in sections 3 to 5. U.K.

2.2. Headlamps must be designed and manufactured in such a way that under the normal conditions of use and despite any vibrations to which they may be exposed they continue to function properly and retain the characteristics required by this Annex. U.K.

2.2.1. Headlamps must be fitted with a device enabling them to be adjusted on the vehicle in such a way as to meet the rules applying to them. This said device does not need to be attached to the parts within which the reflector and diffuser lens cannot be separated, provided that the use of those parts is restricted to vehicles on which the headlamps may be adjusted by other means. U.K.

Where a headlamp emitting a driving beam and a headlamp emitting a passing beam, each being equipped with its own lamp, are grouped together to form a composite unit, the setting device must enable each individual optical system to be set in an appropriate manner.

2.2.2. However, these provisions do not apply to headlamp assemblies whose reflectors are indivisible. In this instance the requirements of section 2 of this Annex shall apply. When more than one light source provides the driving beam those sources must be combined in order to determine the maximum illumination value (E_max). U.K.

2.3. The parts intended to attach the filament lamp to the reflector must be made in such a way that, even in the dark, the filament lamp can be attached without uncertainty in its appropriate position. U.K.

2.4. The correct position of the lens in relation to the optical system must be clearly marked and locked in position in order to avoid any rotation. U.K.

2.5. Where headlamps have been designed in such a way as to meet the requirements of driving on both the right and the left, adaptation to a given rule of the road may be obtained by a suitable initial setting when the vehicle is equipped or via a deliberate action on the part of the user. That initial setting or that deliberate action must, for example, consist of a specific angular setting either of the sealed-beam assembly on the vehicle or of the lamp in relation to that assembly. In all cases only two different setting positions that have been clearly specified and correspond in each case to a rule of the road (driving on the right or left) must be possible and any shift into an intermediate position must be made impossible. When the lamp is able to occupy two different positions the parts intended to attach the lamp to the reflector must be designed and manufactured in such a way that, in each of those two positions, the lamp is attached with the same precision as required for headlamps designed for just one rule of the road. Conformity must be checked visually and, where appropriate, by means of a test assembly. U.K.

2.6. In order to ensure that operation does not involve any excessive variation in photometric performance, additional tests must be carried out as required by Appendix 2. U.K.

2.7. If the lens of the headlamps is of plastic material, additional tests must be carried out in accordance with the requirements of Appendix 3. U.K.

3. ILLUMINATION REQUIREMENTS U.K.

3.1. General requirements U.K.

3.1.1. Headlamps must be designed in such a way that, with adequate HS₁ or R₂ lamps, they emit a light that is not dazzling but is nevertheless adequate on passing beam and provides good illumination on driving beam. U.K.

3.1.2. A screen placed vertically at a distance of 25 m in front of the headlamp, as shown in Appendix 1, must be used to check the illumination produced by the headlamp. U.K.

3.1.3. A colourless reference lamp designed for a nominal voltage of 12 V must be used in examining headlamps. The current at the terminals of the lamp during examination of the headlamp must be set to the following characteristics: U.K.

The headlamp must be considered acceptable if it meets the requirements set out in section 3 with at least one reference lamp which may be presented together with the headlamp.

3.1.4. The dimensions determining the position of the filaments within the HS₁ or R₂ filament reference lamp are set out in Annex IV. U.K.

3.1.5. The bulb for the filament reference lamp must be of such a shape and optical quality that it causes a minimum of reflection or refraction which may have an adverse effect on the light distribution. U.K.

3.2. Requirement relating to the passing beam U.K.

3.2.1. The passing beam must produce a cut-off of such distinctness that it is possible to carry out adjustments correctly using the said cut-off. The cut-off must be a straight horizontal line on the side opposite to the rule of the road for which the headlamp is intended. On the other side the cut-off must not go beyond either broken line HV-H₁ and H₄ formed by a straight line formed by HV-H₁ lying at an angle of 45^o with the horizontal and a straight line H₁-H₄ offset by 1 % in relation to straight line h-h, or straight line HV-H₃ inclined by 15^o to the horizontal (see Appendix 1). In no case is a cut-off going beyond both line HV-H₂ and line H₂-H₄ and resulting from the combination of the two preceding possibilities acceptable. U.K.

3.2.2. The headlamp must be aligned in such a way that: U.K.

3.2.2.1. where headlamps are designed to meet the requirements of driving on the right the cut-off on the left-hand half of the screen must be horizontal and for headlamps designed to meet the requirements of driving on the left the cut-off in the right-hand half of the screen must be horizontal. The setting screen must be sufficiently wide to permit examination of the cut-off over at least 5^o on each side of line v-v; U.K.

3.2.2.3. the tip of the cut-off must be on straight line v-v. If the beam does not have a cut-off, a clear ‘elbow’ lateral setting must be presented in such a way as best to meet the illumination requirements applying to points 75 R and 50 R for driving on the right and point 75 L and 50 L for driving on the left. U.K.

3.2.3. When aligned in this manner the headlamp must meet the requirements referred to in 3.2.5 to 3.2.7 and 3.3. U.K.

3.2.4. Where a headlamp aligned as referred to above does not meet the requirements of 3.2.5 to 3.2.7 and 3.3 it is permissible to alter the setting provided that the axis of the beam is not moved sideways by more than 1^o (= 44 cm) to the right or left. The incorrect setting limit of 1^o to the right or left is not compatible with a vertical incorrect setting upwards or downwards which is restricted only by the requirements laid down in 3.3. However, the horizontal part of the cut-off must not go beyond line h-h. In order to make settings easier by means of the cut-off it is permissible partly to mask the headlamp in order to make the cut-off more distinct. U.K.

1. ADDITIONAL REQUIREMENTS CONCERNING MARKS AND THE MARKING OF DEVICES U.K.

1.1. Headlamps designed in such a way as to meet the requirement of a single rule of the road (driving on either the right or the left) must, on the lens, bear the limits of the area which may possibly be masked in order to avoid distracting road users in a country where the rule of the road is not that for which the headlamp has been designed. However, when that area is directly identifiable by design any such delimitation is not necessary. U.K.

1.2. Headlamps designed in such a way as to meet the requirements of driving on the right and those for driving on the left must bear markings in order to locate the two positions for the fixing in position of the light unit on the vehicle or the lamp on the reflector; these markings consist of the letters ‘R/D’ for the position corresponding to driving on the right and the letters ‘L/G’ for the position corresponding to driving on the left. U.K.

1.3. All headlamps designed in such a way as to preclude any simultaneous lighting-up of the dipped-beam filament and that of any other light source with which they may be associated must be marked with an oblique stroke (/) within the component type-approval mark, after the passing beam-headlamp symbol. U.K.

1.4. Where headlamps meet only the requirements of driving on the left, a horizontal arrow pointing to the right of an observer looking at the headlamp head-on, i.e. towards the side of the road driven upon, must be entered below the component type-approval mark. U.K.

1.5. Where by means of a deliberate alteration in the adjustment of the light unit or lamp, headlamps meet the requirements of both rules of the road, a horizontal arrow having two tips pointing one to the left and the other to the right must be entered below the component type approval mark. U.K.

1.6. The following additional symbol or symbols: U.K.

1.6.1. on headlamps meeting left-hand traffic requirements only, a horizontal arrow pointing to the right of an observer facing the headlamp, i.e. to the side of the road on which traffic moves; U.K.

1.6.2. on headlamps designed to meet the requirements of both traffic systems by means of an appropriate adjustment of the setting of the optical unit or the filament lamp, a horizontal arrow with a head at each end, the heads pointing respectively to the left and to the right; U.K.

1.6.3. on headlamps meeting the requirements of this Directive in respect of the passing beam only, the letters ‘HC’; U.K.

1.6.4. on headlamps meeting the requirements of this Directive in respect of the driving beam only, the letters ‘HR’; U.K.

1.6.5. on headlamps meeting the requirements of this Directive in respect of both the passing and the driving beam, the letters ‘HCR’; U.K.

1.6.6. on headlamps incorporating a lens of plastic material, the letters ‘PL’ to be affixed near the symbols prescribed in 1.6.3 to 1.6.5. U.K.

2. GENERAL SPECIFICATIONS U.K.

2.1. Each sample must conform to the specifications set out in sections 6 to 8. U.K.

2.2. Headlamps must be so made as to retain their prescribed photometric characteristics and to remain in good working order when in normal use, in spite of the vibrations to which they may be subjected. U.K.

2.2.1. Headlamps must be fitted with a device enabling them to be so adjusted on the vehicle in such a way as to comply with the rules applicable to them. Such a device need not be fitted on components in which the reflector and the lens cannot be separated provided the use of such components is confined to vehicles on which the headlamp setting can be adjusted by other means. Where a headlamp providing a driving beam and a headlamp providing a passing beam, each equipped with its own filament lamp, are assembled to form a composite unit, the adjusting device must enable each optical system individually to be duly adjusted. However, this does not apply to headlamp assemblies whose reflectors are indivisible. For this type of assembly, the requiremens of section 6 apply. U.K.

2.3. The components by which the filaments lamp(s) is/are fixed to the reflector must be made in such a way that, even in darkness, the filament lamp(s) can be fixed in no other position but the correct one(3) (4). U.K.

The filament lamp-holder must conform to the dimensional characteristics as given in the following data sheets of CIE Publication 61-2:

Filament lamps	Holder	Data Sheets

H2	X 5111	7005.99.2
H3	PK 22s	7005.47.1
HB3	P 20d	7005.31.1
HB4	P 22d	7005.32.1
H7	PX 26d	7005.5.1
H4	P43t-38	7005.39.2

2.4. Headlamps designed to satisfy the requirements of both right-hand and left-hand traffic may be adapted for traffic on a given side of the road either by an appropriate initial setting when fitted on the vehicle or by selective setting by the user. Such initial or selective setting may consist, for example, of fixing either the optical unit at a given angle on the vehicle or the filament lamp at a given angle in relation to the optical unit. In all cases, only two precise setting positions, one for right-hand and one for left-hand traffic, must be possible, and the design must preclude inadvertent shifting of the headlamp from one position to the other or its setting in an intermediate position. Where two different setting positions are provided for the filament lamp, the components attaching the filament lamp to the reflector must be designed and made so that, in each of its two settings, the filament lamp is held in position with the precision required for headlamps intended for traffic on only one side of the road. Conformity with the requirements of this section must be verified visually and, where necessary, by a test fitting. U.K.

2.5. Only for headlamps equipped with single-filament halogen lamps: On headlamps designed to provide alternately a driving beam and a passing beam, any mechanical, eletro-mechanical or other device incorporated in the headlamp for switching from one beam to the other(5) must be so constructed that: U.K.

2.5.1. the device is strong enough to be worked 50 000 times without suffering damage despite the vibration to which it may be subjected in normal use; U.K.

2.5.3. either the passing beam or the driving beam can always be obtained without any possibility of the mechanism stopping in between the two positions; U.K.

2.5.4. the user cannot, with ordinary tools, change the shape or position of the moving parts. U.K.

2.6. Complementary tests must be carried out in accordance with the requirements of Appendix 2 to ensure that in use there is no excessive change in photometric performance. U.K.

2.7. If the lens of the headlamp is of plastic material, tests must be carried out in accordance with the requirements of Appendix 3. U.K.

3. ILLUMINATION U.K.

3.1. General provisions U.K.

3.1.1. Headlamps must be made in such a way that, with suitable H₁, H₂, H₃, HB₃, HB₄, H₇ and/or H₄ filament lamps, they provide adequate illumination without dazzle in the case of the passing beam and good illumination in the case of the driving beam. U.K.

3.1.2. The illumination produced by the headlamp must be checked on a vertical screen set at a distance of 25 m in front of the headlamp and at right angles to its axis (see Appendix 1). U.K.

3.1.3. The headlamps must be checked by means of (a) standard (reference) filament lamp(s) designed for a rated voltage of 12 V. During the checking of the headlamp, the voltage at the terminals of the filament lamp must be regulated so as to obtain the following characteristics: U.K.

The headlamp is deemed satisfactory if the photometric requirements are met with at least one standard (reference) 12-volt filament lamp which may be supplied with the headlamp.

3.1.4. The dimensions determining the position of the filament inside the standard (reference) 12-volt filament lamp are shown on the relevant data sheet of Annex 4. U.K.

3.1.5. The bulb of the standard (reference) filament lamp must be of such optical shape and quality that it does not cause any reflection or refraction adversely affecting the light distribution. Compliance with this requirement must be checked by measuring the light distribution obtained when a standard headlamp is fitted with the standard (reference) filament lamp. U.K.

3.2. Provisions regarding passing beams U.K.

3.2.1. The passing beam must produce a sufficiently sharp cut-off to permit satisfactory adjustment with its aid.

3.2.2.1. in the case of headlamps designed to meet the requirements of right-hand traffic, the cut-off on the left half of the screen(6) is horizontal and in the case of headlamps designed to meet the requirements of left-hand traffic, the cut-off on the right half of the screen is horizontal. U.K.

3.2.2.2. this horizontal part of the cut-off is situated 25 cm below the line h-h (see Appendix 1); U.K.

3.2.2.3. the elbow of the cut-off is on line v-v(7). U.K.

3.2.4. Where a headlamp so aimed does not meet the requirements of 3.2.5 to 3.2.7 and 3.3, its alignment may be changed provided that the axis of the beam is not laterally displaced by more than 1^o (= 44 cm) to the right or left(9). To faciltate adjustment by means of the cut-off, the headlamp may be partially occluded in order to sharpen the cut-off. U.K.

3.2.5. The illumination produced on the screen by the passing beam must meet the following requirements: U.K.

a E50 R and E50 L are the illuminations actually measured.

3.3. Provisions regarding driving beams U.K.

3.3.1. In the case of a headlamp designed to provide a driving beam and a passing beam, measurements of the illumination produced on the screen by the driving beam must be taken with the same headlamp alignment as for measurements under 3.2.5 to 3.2.7.

TESTS ON COMPLETE HEADLAMPS U.K.

Once the photometric values have been measured according to the requirements of this Directive, in points E_max for driving beam and HV, 50 R, B 50 L for passing beam (or HV, 50 L, B 50 R for headlamps designed for left-hand traffic) a complete headlamp sample is tested for stability of photometric performance in operation. ‘Complete headlamp’ is understood to mean the complete lamp itself including those surrounding body parts and lamps which could influence its thermal dissipation.

1. TEST OF STABILITY OF PHOTOMETRIC PERFORMANCE U.K.

The tests are carried out in a dry and still atmosphere at an ambient temperature of 23 ^oC ± 5 ^oC, the complete headlamp being mounted on a base representing the correct installation on the vehicle.

1.1. Clean headlamp U.K.

The headlamp is operated for 12 hours as described in 1.1.1 and checked as prescribed in 1.1.2.

1.1.1. Test procedure U.K.

The headlamp is operated for a period according to the specified time, so that:

1.1.1.1.

(a)

in the case where only one lighting function (driving or passing beam) is to be approved, the corresponding filament is for the prescribed time(10),

(b)

in the case of a reciprocally incorporated passing lamp and driving lamp (dual-filament lamp or two filament lamps):

• If the applicant declares that the headlamp is to be used with a single filament lit(11), the test is carried out in accordance with this condition activating(10) each specified function successfully for half the time specified in 1.1,

• in all other cases(12) (13), the headlamp is subjected to the following cycle until the time specified is reached:

  • 15 minutes, passing beam filament lit

  • 5 minutes, all filaments lit,

(c)

in the case of grouped lighting functions all the individual functions must be lit simultaneously for the time specified for individual lighting functions (a) also taking into account the use of reciprocally incorporated lighting functions (b), according to the manufacturer's specifications.

1.1.1.2. Test voltage U.K.

The voltage must be adjusted so as to supply 90 % of the maximum wattage specified in Annex IV. The applied wattage must in all cases comply with the corresponding value of a filament lamp of 12 V rated voltage, except if the applicant for approval specifies that the headlamp may be used at a different voltage. In the latter case, the test is carried out with the filament lamp whose wattage is the highest that can be used.

1.1.2. Test results U.K.

1.1.2.1. Visual inspection U.K.

Once the headlamp has been stabilized to the ambient temperature, the headlamp lens and the external lens, if any, must be cleaned with a clean, damp cloth. It must then be inspected visually; no distortion, deformation, cracking or change in colour of either the headlamps or the external lens, if any, must be noticeable.

1.1.2.2. Photometric test U.K.

To comply with the requirements of this directive, the photometric values must be verified in the following points:

Passing beam:

• 50 R — B 50 L — HV for headlamps designed for right-hand traffic,

• 50 L — B 50 R — HV for headlamps designed for left-hand traffic.

Driving beam:

• Point of E_max.

  Another adjustment may be carried out to allow for any deformation of the headlamp base due to heat (the change of the position of the cut-off line is covered in section 2 of this Appendix).

  A 10 % discrepancy between the photometric characteristics and the values measured prior to the test is permissible, including the tolerances of the photometric procedure.

1.2. Dirty headlamp, U.K.

After being tested as specified in 1.1, the headlamp must be operated for one hour as described in 1.1.1, after being prepared as prescribed in 1.2.1, and checked as prescribed in 1.1.2.

1.2.1. Preparation of the headlamp U.K.

1.2.1.1. Test mixture U.K.

The mixture of water and polluting agent to be applied to the headlamp must be composed of nine parts (by mass) of silica sand with a grain size distributed between 0 and 100 µm, one part (by mass) of vegetal carbon dust of a grain size distributed between 0 and 100 µm, 0,2 (by mass) of NaCMC(14) and an appropriate quantity of distilled water, the conductivity of which is lower than 1 mS/m for the purpose of this test.

The mixture must not be more than 14 days old.

1.2.1.2. Application of the test mixture to the headlamp U.K.

The test mixture must be uniformly applied to the entire light-emitting surface of the headlamp and then left to dry. This procedure is repeated until the illuminating value has dropped to 15 — 20 % of the values measured for each following point under the conditions described in paragraph 1 above:

• E_max in driving beam for a driving/passing lamp,

• E_max in driving beam for a driving lamp only.

• 50 R and 50 V(15) for a passing lamp only, designed for right-hand traffic.

• 50 L and 50 V for a passing lamp only, designed for left-hand traffic.

1.2.1.3. Measuring equipment U.K.

The measuring equipment must be equivalent to that used during headlamp approval tests. A standard (reference) filament lamp is used for the photometric verification.

2. TEST FOR CHANGE IN VERTICAL POSITION OF THE CUT-OFF LINE UNDER THE INFLUENCE OF HEAT U.K.

This test consists of verifying that the vertical drift of the cut-off line under the influence of heat does not exceed a specified value for an operating passing lamp.

The headlamp tested in accordance with section 1 must be subjected to the test described in 2.1 without being removed from or readjusted in relation to its test fixture.

2.1. Test U.K.

The test must be carried out in a dry and still atmosphere at an ambient temperature of 23 ^oC ± 5 ^oC.

Using a series-production filament lamp which has been aged for at least one hour the headlamp is operated on passing beam without being removed from or readjusted in relation to its test fixture. (For the purpose of this test, the voltage must be adjusted as specified in 1.1.1.2.) The position of the cut-off line in its horizontal part (between VV and the vertical line passing through point B 50 R for left-hand traffic or B 50 L for right-hand traffic) must be verified 3 minutes (r₃) and 60 minutes (r₆₀) after operation.

The measurement of the variation in the cut-off line position as described above is carried out by any method giving acceptable accuracy and reproducible results.

2.2. Test results U.K.

The result expressed in milliradians (mrad) is considered as acceptable when the absolute value recorded on the headlamp is not more than 1,0 mrad ( Δr₁ ≤ 1,0 mrad).

2.2.1. However, if this value is more than 1,0 mrad but not more than 1,5 mrad (1,0 mrad < Δr₁ ≤ 1,5 mrad) a second headlamp must be tested as described in 2.1 after being subjected three consecutive times to the cycle as described below, in order to stabilize the position of mechanical parts of the headlamp on a base representative of the correct installation on the vehicle: U.K.

• Operation of the passing lamp for one hour (the voltage must be adjusted as specified in 1.1.1.2.)

• Period of rest for one hour.

The headlamp type is considered as acceptable if the mean value of the absolute values Δr

₁

measured on the first sample and Δr

₁₁

measured on the second sample is not more than 1,0 mrad.

Method of measurement of the diffusion and transmission of light

1. EQUIPMENT (see figure) U.K.

The beam of a collimator K with a half divergence

is limited by a diaphragm D_T with an opening of 6 mm against which the sample stand is placed.

A convergent achromatic lens L

₂

corrected for spherical aberrations, links the diaphragm D

_T

with the receiver R; the diameter of the lens L

₂

must be such that it does not diaphragm the light diffused by the sample in a cone with a half top angle

An annular diaphragm D_D with angles and is

placed in an image focal plane of the lens L₂.

The non-transparent central art of the diaphragm is necessary in order to eliminate the light arriving directly from the light source. It must be possible to remove the central part of the diaphragm from the light beam in such a manner that it returns exactly to its original position.

The distance L₂ D_T and the focal length F₂ (16) of the lens L₂ must be so chosen that the image of D_T completely covers the receiver R.

When the initial incident flux is referred to 1 000 units, the absolute precision of each reading must be better than 1 unit.

2. MEASUREMENT U.K.

The following readings are taken:

Reading	with sample	with central part of DD	Quantity represented
T1	no	no	Incident flux in initial reading
T2	yes (before test)	no	Flux transmitted by the new material in a field of 24 oC
T3	yes (after test)	no	Flux transmitted by the tested material in a field of 24 oC
T4	yes (before test)	yes	Flux diffused by the new material
T5	yes (after test)	yes	Flux diffused by the tested material

Appendix 3.3

Spray testing method

1.1. Spray gun U.K.

The spray gun used must be equipped with a nozzle 1,3 mm in diameter allowing a liquid flow-rate of 0,24 ± 0,02 1/minute at an operating pressure of 6,0 bars − 0, + 0,5 bar.

Under these operating conditions the fan pattern obtained must be 170 mm ± 50 mm in diameter on the surface exposed to deterioration, at a distance of 380 mm ± 10 mm from the nozzle.

1.2. Test mixture U.K.

The test mixture is composed of:

• Silica sand of hardness 7 on the Mohs scale, with a grain size between 0 and 0,2 mm and an almost normal distribution, with an angular factor of 1,8 to 2;

• Water of hardness not exceeding 205 g/m³ for a mixture comprising 25 g of sand per litre of water

2. TEST U.K.

The outer surface of the lamp lenses is subjected once or more than once to the action of the sand jet produced as described above. the jet must be sprayed almost perpendicular to the surface to be tested.

The deterioration is checked by means of one or more samples of glass placed as a reference near the lenses to be tested. The mixture must be sprayed until the variation in the diffusion of light on the sample or samples measured by the method described in Appendix 2 is such that:

Several reference samples may be used to check that the whole surface to be tested has deteriorated homogeneously.

Appendix 3.4

Adhesive tape adherence test

1. PURPOSE U.K.

This method allows to determination under standard conditions of the linear force of adhesion of an adhesive tape to a glass plate.

2. PRINCIPLE U.K.

Measurement of the force necessary to unstick an adhesive tape from a glass plate at an angle of 90^o.

3. SPECIFIED ATMOSPHERIC CONDITIONS U.K.

The ambient conditions must be at 23 ^oC ± 5 ^oC and 65 % ± 15 % relative humidity (RH).

4. TEST-PIECES U.K.

Before the test, the sample roll of adhesive tape must be conditioned for 24 hours in the specified atmosphere (see section 3 above).

Five test-pieces each 400 mm long are tested from each roll. These test-pieces are taken from the roll after the first three turns have been discarded.

5. PROCEDURE U.K.

The test must be carried out under the ambient conditions specified in section 3.

The five test pieces are taken while the tape is radially unrolled at a speed of approximately 300 mm/s, and the test-pieces are then applied within 15 seconds in the following manner:

• The tape is applied to the glass plate progressively with a slight lengthwise rubbing movement of the finger, without excessive pressure, in such a manner as to leave no air bubble between the tape and the glass plate.

• The assembly is left in the specified atmospheric conditions for 10 minutes.

• About 25 mm of the test-piece is unstuck from the plate in a plane perpendicular to the axis of the test-piece.

• The plate is fixed and the free end of the tape folded back at 90^o. Force is applied in such a manner that the separation line between the tape and the plate is perpendicular to this force and perpendicular to the plate.

• The tape is then pulled to unstick at a speed of 300 mm/s and the force required is recorded.

6. RESULTS U.K.

The five values obtained are arranged in order and the median value taken as the results of the measurement. This value is expressed in Newtons per centimetre of width of the tape.

SHEET C21W/2 Screen projection requirements U.K.

This test is used to determine whether a filament lamp complies with the requirements, by checking whether the filament is correctly positioned relative to the reference axis and to the centre of the lamp's lenght.

	a	h	k
12 V	4,0 + d	14,5	2,0

d = nominal diameter of filament as stated by the manufacturer.

For standard filament lamp: a = 2,0 + d k = 0,5

Test procedure and requirements U.K.

1. The lamp is placed in a holder (socket) capable of being so rotated through 360^o about the reference axis that the front elevation is seen on the screen on to which the image of the filament is projected. The reference plane on the screen must coincide with the centre of the lamp. The central axis sought on the screen must coincide with the centre of the lamp's length. U.K.

2. Front elevation U.K.

2.1. The projection of the filament must lie entirely within the rectangle when the lamp is rotated through 360^o. U.K.

2.2. The centre of the filament must not be offset by more than the distance ‘k’ from the central axis sought. U.K.

Example of the arrangement of the approval mark

The above EC component type-approval mark affixed to a filament lamp indicates that the lamp has been approved in Germany (e1) under the approval number A3. The first character of the approval code (0) indicates that the approval was granted in accordance with the requirements of Annex IV to this Directive in its original form.

Appendix 24

Luminous centre and shapes of lamp filaments

Save as possibly otherwise indicated on the lamp data sheets, this standard is applicable to the determination of the luminous centre of different filament shapes if the filament is shown as a point in at least one view in the lamp data sheets.

The position of the luminous centre depends upon the filament shape.

No	Filament shapes	Observations
1		With b > 1,5 h, the deviation of the filament axis with respect to a plane normal to the reference axis must not exceed 15o.
2		Only applicable to filaments which can be inscribed in a rectangle of b > 3 h.
3		Applicable to filaments which can be inscribed in a rectangle of b < 3 h, where however k < 2 h.

The side lines of the circumscribed rectangle in Nos 2 and 3 are parallel and perpendicular, respectively, to the reference axis.

The luminous centre is the point of intersection of the dash-dot lines.

Editorial Information

X1 Substituted by Corrigendum to Directive 97/24/EC of the European Parliament and of the Council of 17 June 1997 on certain components and characteristics of two- or three-wheel motor vehicles (Official Journal of the European Communities L 226 of 18 August 1997).

(1)

Headlamps of Annex III-B, III-C and III-D.

(2)

The measuring screen for driving on the left must be symmetrical to line v-v shown in the diagram in this Annex.

(3)

Technical requirements for filament lamps: see Annex IV.

(4)

A headlamp is regarded as satisfying the requirements of this paragraph if the filament lamp can easily be fitted into the headlamp and the positioning lugs can be correctly fitted into their slots even in darkness.

(5)

These provisions do not apply to the control switch.

(6)

The test screen must be sufficiently wide to allow examination of the cut-off over a range of at least 5^o each side of the line v-v.

(7)

If, in the case of headlamp designed to satisfy the requirements of this Directive with respect to the passing beam only, the focal axis diverges appreciably from the general direction of the beam, or if, whatever the type of headlamp (passing only or combined passing and driving), the beam does not have a cut-off with a clear elbow, the lateral adjustment must be affected in the manner which best satisfies the requirements for illumunation at points 75 R and 50 R for right-hand traffic and at points 75 L and 50 L for left-hand traffic.

(8)

A headlamp designed to emit a passing beam may incorporate a driving beam not complying with this specification.

(9)

The limit of re-alignment of 1^o towards the right or left is not incompatible with upward or downward vertical re-alignment. The latter is limited only by the requirements laid down in section 3.3; however, the horizontal part of the cut-off should not extend beyond the line h-h (the provisions of section 3.3 are not applicable to headlamps intended to meet the requirements of this Annex for passing beam only).

(10)

When the tested headlamp is grouped and/or reciprocally incorporated with signalling lamps, the latter must be lit for the duration of the test. In the case of a direction indicator lamp, it must be lit in flashing operation mode with an on/off time ratio of approximately one to one.

(11)

If two or more lamp filaments are simultaneously lit when headlamp flashing is used, this is not considered as being normal use of the filament simultaneously.

(12)

When the tested headlamp is grouped and/or reciprocally incorporated with signalling lamps, the latter must be lit for the duration of the test. In the case of a direction indicator lamp, it must be lit in flashing operation mode with an on/off time ratio of approximately one to one.

(13)

If two or more lamp filaments are simultaneously lit when headlamp flashing is used, this is not considered as being normal use of the filament simultaneously.

(14)

NaCMC represents the sodium salt of carboxymethylcellulose, customarily referred to as CMC. The NaCMC used in the dirt mixture must have a degree of substitution (DS) of 0,6-0,7 and a viscosity of 200-300 cP for a 2 % solution 20 ^oC.

(15)

50 V is situated 375 mm below HV on the vertical line v-v on the screen at 25 m distance.

(16)

For L₂ the use of a focal distance of about 80 mm is recommended.

(17)

The points to be measured are those where the outside of the end turn that is nearest to or furthest from the cap crosses the filament axis.

(18)

The cap must be pressed in these directions.

(19)

The end of the filament is defined at sheet H₂/3.

(20)

The drawing is not mandatory with respect to the design of the shield.

(21)

The drawing is not mandatory with respect to the design of the shield.
