THE EUROPEAN PARLIAMENT AND THE COUNCIL OF THE EUROPEAN UNION,
Having regard to the Treaty establishing the European Community, and in particular Article 95 thereof,
Having regard to the proposal from the Commission(1),
Having regard to the Opinion of the European Economic and Social Committee(2),
Acting in accordance with the procedure laid down in Article 251 of the Treaty(3),
Whereas:
(1) A number of measuring instruments are covered by specific Directives, adopted on the basis of Council Directive 71/316/EEC of 26 July 1971 on the approximation of the laws of the Member States relating to common provisions for both measuring instruments and methods of metrological control(4). Specific Directives that are technically outdated should be repealed and replaced by an independent Directive reflecting the spirit of the Council Resolution of 7 May 1985 on a new approach to technical harmonisation and standards(5).
(2) Correct and traceable measuring instruments can be used for a variety of measurement tasks. Those responding to reasons of public interest, public health, safety and order, protection of the environment and the consumer, of levying taxes and duties and of fair trading, which directly and indirectly affect the daily life of citizens in many ways, may require the use of legally controlled measuring instruments.
(3) Legal metrological control should not lead to barriers to the free movement of measuring instruments. The provisions concerned should be the same in all Member States and proof of conformity accepted throughout the Community.
(4) Legal metrological control requires conformity with specified performance requirements. The performance requirements that the measuring instruments must meet should provide a high level of protection. The conformity assessment should provide a high level of confidence.
(5) Member States should as a general rule prescribe legal metrological control. Where legal metrological control is prescribed, only measuring instruments complying with common performance requirements should be used.
(6) The principle of optionality introduced by this Directive, whereby Member States may exercise their right to decide whether or not to regulate any of the instruments covered by this Directive, should be applicable only to the extent that this will not cause unfair competition.
(7) The responsibilities of the manufacturer for compliance with the requirements of this Directive should be specifically stated.
(8) The performance of measuring instruments is particularly sensitive to the environment, particular the electromagnetic environment. Immunity of measuring instruments to electromagnetic interference forms an integral part of this Directive and the immunity requirements of Council Directive 89/336/EEC of 3 May 1989 on the approximation of the laws of the Member States relating to electromagnetic compatibility(6) should therefore not apply.
(9) Community legislation should specify essential requirements that do not impede technical progress, preferably performance requirements. Provisions to remove technical barriers to trade should follow the Council Resolution of 7 May 1985 on a new approach to technical harmonisation and standards.
(10) In order to take account of differences in climatic conditions or of different levels of consumer protection that may apply at national level, essential requirements may give rise to the establishment of environmental or accuracy classes.
(11) In order to ease the task of proving conformity with the essential requirements and to enable conformity to be assessed, it is desirable to have harmonised standards. Such harmonised standards are drawn up by private-law bodies and should retain their status as non-mandatory texts. To this end, the European Committee for Standardisation (CEN), the European Committee for Electrotechnical Standardisation (CENELEC) and the European Telecommunications Standards Institute (ETSI) are recognised as the competent bodies for the adoption of harmonised standards in accordance with the general guidelines on cooperation between the Commission and the European Standardisation bodies signed on 13 November 1984.
(12) The technical and performance specifications of internationally agreed normative documents may also comply, in part or in full, with the essential requirements laid down by this Directive. In those cases the use of these internationally agreed normative documents can be an alternative to the use of harmonised standards and, under specific conditions, give rise to a presumption of conformity.
(13) Conformity with the essential requirements laid down by this Directive can also be provided by specifications that are not supplied by a European technical standard or an internationally agreed normative document. The use of European technical standards or internationally agreed normative documents should therefore be optional.
(14) The conformity assessment of sub-assemblies should respect the provisions of this Directive. If sub-assemblies are traded separately and independently of an instrument, the exercise of conformity assessment should be undertaken independently of the instrument concerned.
(15) The state of the art in measurement technology is subject to constant evolution which may lead to changes in the needs for conformity assessments. Therefore, for each category of measurement and, where appropriate, sub-assemblies, there must be an appropriate procedure or a choice between different procedures of equivalent stringency. The procedures adopted are as required by Council Decision 93/465/EEC of 22 July 1993 concerning the modules for the various phases of the conformity assessment procedures and the rules for the affixing and use of the ‘CE’ marking, which are intended to be used in the technical harmonisation Directives(7). However, derogations may have to be made for these modules in order to reflect specific aspects of metrological control. Provision should be made for the ‘CE’ marking to be affixed during the fabrication process.
(16) Continued development in measurement technology as well as concerns expressed by stakeholders about certification, stress the need to ensure consistent conformity assessment procedures for industrial products, as requested by the Council Resolution adopted on 10 November 2003(8).
(17) Member States should not impede the placing on the market and/or putting into use of measuring instruments that carry the ‘CE’ marking and supplementary metrology marking in accordance with the provisions of this Directive.
(18) Member States should take appropriate action to prevent non-complying measuring instruments from being placed on the market and/or put into use. Adequate cooperation between the competent authorities of the Member States is therefore necessary to ensure a Community-wide effect of this objective.
(19) Manufacturers should be informed of the grounds on which negative decisions in respect of their products were taken, and of the legal remedies available to them.
(20) Manufacturers should be offered the possibility to exercise the rights obtained before the entry into force of this Directive, during a reasonable transitional period.
(21) National specifications concerning the appropriate national requirements in use should not interfere with the provisions of this Directive on ‘putting into use’.
(22) The measures necessary for the implementation of this Directive should be adopted in accordance with Council Decision 1999/468/EC of 28 June 1999 laying down the procedures for the exercise of implementing powers conferred on the Commission(9).
(23) The activity of the Measuring Instruments Commmittee should include proper consultations with representatives of interested parties.
(24) Directives 71/318/EEC, 71/319/EEC, 71/348/EEC, 73/362/EEC, 75/33/EEC, as concerns the meters defined in Annex MI-001 of this Directive, 75/410/EEC, 76/891/EEC, 77/95/EEC, 77/313/EEC, 78/1031/EEC and 79/830/EEC should therefore be repealed,

2.Member States shall apply the criteria set out in Article 12 for the designation of such bodies. Bodies that meet the criteria laid down in the national standards which transpose the relevant harmonised standards, the references of which have been published in the Official Journal of the European Union, shall be presumed to meet the corresponding criteria. Member States shall publish the references to these national standards.
If a Member State has not introduced national legislation for tasks mentioned under Article 2, it shall retain the right to designate and notify a body for tasks relating to that instrument.
3.A Member State that has notified a body shall:
ensure that the body continues to meet the criteria set out in Article 12,
withdraw such notification if it finds that the body no longer meets those criteria.
It shall forthwith inform the other Member States and the Commission of any such withdrawal.
4.Each of the bodies to be notified shall be given an identification number by the Commission. The Commission shall publish the list of notified bodies, together with the information in respect of the scope of the notification referred to in paragraph 1, in the Official Journal of the European Union, C series, and shall ensure that the list is kept up to date.
Member States shall apply the following criteria for the designation of bodies in accordance with Article 11(1).
The body, its director and staff involved in conformity assessment tasks shall not be the designer, manufacturer, supplier, installer or user of the measuring instruments that they inspect, nor the authorised representative of any of them. In addition, they may not be directly involved in the design, manufacture, marketing or maintenance of the instruments, nor represent the parties engaged in these activities. The preceding criterion does not, however, preclude in any way the possibility of exchanges of technical information between the manufacturer and the body for the purposes of conformity assessment.
The body, its director and staff involved in conformity assessment tasks shall be free from all pressures and inducements, in particular financial inducements, that might influence their judgement or the results of their conformity assessment, especially from persons or groups of persons with an interest in the results of the assessments.
The conformity assessment shall be carried out with the highest degree of professional integrity and requisite competence in the field of metrology. Should the body subcontract specific tasks, it shall first ensure that the subcontractor meets the requirements of this Directive, and in particular of this Article. The body shall keep the relevant documents assessing the subcontractor's qualifications and the work carried out by him under this Directive at the disposal of the notifying authority.
The body shall be capable of carrying out all the conformity assessment tasks for which it has been designated, whether those tasks are carried out by the body itself or on its behalf and under its responsibility. It shall have at its disposal the necessary staff and shall have access to the necessary facilities for carrying out in a proper manner the technical and administrative tasks entailed in conformity assessment.
The body's staff shall have:
sound technical and vocational training, covering all conformity assessment tasks for which the body was designated;
satisfactory knowledge of the rules governing the tasks which it carries out, and adequate experience of such tasks;
the requisite ability to draw up the certificates, records and reports demonstrating that the tasks have been carried out.

the rated operating conditions,
the critical change values,
disturbances,
3.Where a Member State or the Commission considers that a normative document whose references have been published in the Official Journal of the European Union, C series, in accordance with paragraph 1(b), does not fully meet the essential requirements referred to in Annex I and in the relevant instrument-specific Annexes, that Member State or the Commission shall bring the matter before the Measuring Instruments Committee, giving the reasons for doing so.
The Commission, acting in accordance with the procedure referred to in Article 15(2), shall inform the Member States whether or not it is necessary to withdraw the references to the normative document concerned from publication in the Official Journal.
4.Member States may take appropriate measures to consult interested parties at national level about OIML work relating to the scope of this Directive.
1.The ‘CE’ marking referred to in Article 7 consists of the symbol ‘CE’ according to the design laid down in paragraph I.B(d) of the Annex to Decision 93/465/EEC. The ‘CE’ marking shall be at least 5 mm high.
2.The supplementary metrology marking consists of the capital letter ‘M’ and the last two digits of the year of its affixing, surrounded by a rectangle. The height of the rectangle shall be equal to the height of the ‘CE’ marking. The supplementary metrology marking shall immediately follow the ‘CE’ marking.
3.The identification number of the notified body concerned referred to in Article 11, if prescribed by the conformity assessment procedure, shall follow the ‘CE’ marking and supplementary metrology marking.
4.When a measuring instrument consists of a set of devices, not being sub-assemblies, operating together, the markings shall be affixed on the instrument's main device.
When a measuring instrument is too small or too sensitive to carry the ‘CE’ marking and supplementary metrology marking, the markings shall be carried by the packaging, if any, and by the accompanying documents required by this Directive.
5.The ‘CE’ marking and supplementary metrology marking shall be indelible. The identification number of the notified body concerned shall be indelible or self destructive upon removal. All markings shall be clearly visible or easily accessible.
1.Member States shall take all appropriate measures to ensure that measuring instruments that are subject to legal metrological control but do not comply with applicable provisions of this Directive are neither placed on the market nor put into use.
2.The competent authorities of the Member States shall assist each other in the fulfilment of their obligations to carry out market surveillance.
In particular, the competent authorities shall exchange:
information concerning the extent to which instruments they examine comply with the provisions of this Directive, and the results of such examinations;

1.Where a Member State establishes that all or part of the measuring instruments of a particular model that bear the ‘CE’ marking and the supplementary metrology marking do not satisfy the essential requirements relating to metrological performance set out in this Directive, when correctly installed and used in accordance with the manufacturer's instructions, it shall take all appropriate measures to withdraw these instruments from the market, prohibit or restrict their further being placed on the market, or prohibit or restrict their further being used.
When deciding on the above measures, the Member State shall take account of the systematic or incidental nature of the non-compliance. Where the Member State has established that the non-compliance is of a systematic nature, it shall immediately inform the Commission of the measures taken, indicating the reasons for its decision.
2.The Commission shall enter into consultation with the parties concerned as soon as possible.
(a)Should the Commission find that the measures taken by the Member State concerned are justified, it shall immediately inform that Member State thereof, as well as the other Member States.
The competent Member State shall take appropriate action against any person who affixed the markings and shall inform the Commission and the other Member States thereof.
If the non-compliance is attributed to shortcomings in the standards or normative documents, the Commission shall, after consulting the parties concerned, bring the matter as soon as possible before the appropriate Committee referred to in Articles 14 or 15.
(b)Should the Commission find that the measures taken by the Member State concerned are not justified, it shall immediately inform that Member State thereof, as well as the manufacturer concerned or his authorised representative.
The Commission shall ensure that the Member States are kept informed of the progress and outcome of the procedure.
1.Where a Member State establishes that the ‘CE’ marking and supplementary metrology marking have been affixed unduly, the manufacturer or his authorised representative shall be obliged:
to make the instrument conform as regards those provisions concerning the ‘CE’ marking and supplementary metrology marking not covered by Article 19(1) and
to end the infringement under the conditions imposed by the Member State.
2.Should the infringement described above persist, the Member State must take all appropriate measures to restrict or prohibit the placing on the market of the instrument in question or to ensure that it is withdrawn from the market or prohibit or restrict its further use in accordance with the procedures laid down in Article 19.
Any decision taken pursuant to this Directive entailing the withdrawal from the market of a measuring instrument, or prohibiting or restricting the placing on the market or putting into use of an instrument, shall state the exact grounds on which it is based. The decision shall be notified forthwith to the party concerned, who shall at the same time be informed of the legal remedies available to him under the law of the Member State concerned and of the time limits to which such remedies are subject.

This Directive shall enter into force on the day of its publication in the Official Journal of the European Union.
This Directive is addressed to the Member States.
A measuring instrument shall provide a high level of metrological protection in order that any party affected can have confidence in the result of measurement, and shall be designed and manufactured to a high level of quality in respect of the measurement technology and security of the measurement data.
The requirements that shall be met by measuring instruments are set out below and are supplemented, where appropriate, by specific instrument requirements in Annexes MI-001 to MI-010 that provide more detail on certain aspects of the general requirements.
The solutions adopted in the pursuit of the requirements shall take account of the intended use of the instrument and any foreseeable misuse thereof.
The measurand is the particular quantity subject to measurement.
An influence quantity is a quantity that is not the measurand but that affects the result of measurement.
The rated operating conditions are the values for the measurand and influence quantities making up the normal working conditions of an instrument.
An influence quantity having a value within the limits specified in the appropriate requirement but outside the specified rated operating conditions of the measuring instrument. An influence quantity is a disturbance if for that influence quantity the rated operating conditions are not specified.
The critical change value is the value at which the change in the measurement result is considered undesirable.
A material measure is a device intended to reproduce or supply in a permanent manner during its use one or more known values of a given quantity.
A trading transaction is direct sales if:
the measurement result serves as the basis for the price to pay and;
at least one of the parties involved in the transaction related to measurement is a consumer or any other party requiring a similar level of protection and;
all the parties in the transaction accept the measurement result at that time and place.
Climatic environments are the conditions in which measuring instruments may be used. To cope with climatic differences between the Member States, a range of temperature limits has been defined.
A utility is regarded as a supplier of electricity, gas, heat or water.
Unless stated otherwise in the instrument-specific annexes, MPE is expressed as a bilateral value of the deviation from the true measurement value.
Where the instrument is intended to be used in a specified permanent continuous electromagnetic field the permitted performance during the radiated electromagnetic field-amplitude modulated test shall be within MPE.
The manufacturer shall specify the upper temperature limit and the lower temperature limit from any of the values in Table 1 unless otherwise specified in the Annexes MI-001 to MI-010, and indicate whether the instrument is designed for condensing or non-condensing humidity as well as the intended location for the instrument, i.e. open or closed.
Temperature Limits | ||||
---|---|---|---|---|
Upper temperature limit | 30 °C | 40 °C | 55 °C | 70 °C |
Lower temperature limit | 5 °C | – 10 °C | – 25 °C | – 40 °C |
Mechanical environments are classified into classes M1 to M3 as described below.
This class applies to instruments used in locations with vibration and shocks of low significance, e.g. for instruments fastened to light supporting structures subject to negligible vibrations and shocks transmitted from local blasting or pile-driving activities, slamming doors, etc.
This class applies to instruments used in locations with significant or high levels of vibration and shock, e.g. transmitted from machines and passing vehicles in the vicinity or adjacent to heavy machines, conveyor belts, etc.
This class applies to instruments used in locations where the level of vibration and shock is high and very high, e.g. for instruments mounted directly on machines, conveyor belts, etc.
The following influence quantities shall be considered in relation with mechanical environments:
Vibration;
Mechanical shock.
Electromagnetic environments are classified into classes E1, E2 or E3 as described below, unless otherwise laid down in the appropriate instrument-specific annexes.
This class applies to instruments used in locations with electromagnetic disturbances corresponding to those likely to be found in residential, commercial and light industrial buildings.
This class applies to instruments used in locations with electromagnetic disturbances corresponding to those likely to be found in other industrial buildings.
This class applies to instruments supplied by the battery of a vehicle. Such instruments shall comply with the requirements of E2 and the following additional requirements:
voltage reductions caused by energising the starter-motor circuits of internal combustion engines,
load dump transients occurring in the event of a discharged battery being disconnected while the engine is running.
The following influence quantities shall be considered in relation with electromagnetic environments:
Voltage interruptions,
Short voltage reductions,
Voltage transients on supply lines and/or signal lines,
Electrostatic discharges,
Radio frequency electromagnetic fields,
Conducted radio frequency electromagnetic fields on supply lines and/or signal lines,
Surges on supply lines and/or signal lines.
Voltage variation,
Mains frequency variation,
Power frequency magnetic fields,
Any other quantity likely to influence in a significant way the accuracy of the instrument.
Essential requirements specified in 1.1 and 1.2 shall be verified for each relevant influence quantity. Unless otherwise specified in the appropriate instrument-specific annex, these essential requirements apply when each influence quantity is applied and its effect evaluated separately, all other influence quantities being kept relatively constant at their reference value.
Metrological tests shall be carried out during or after the application of the influence quantity, whichever condition corresponds to the normal operational status of the instrument when that influence quantity is likely to occur.
According to the climatic operating environment in which the instrument is intended to be used either the damp heat-steady state (non-condensing) or damp heat cyclic (condensing) test may be appropriate.
The damp heat cyclic test is appropriate where condensation is important or when penetration of vapour will be accelerated by the effect of breathing. In conditions where non-condensing humidity is a factor the damp-heat steady state is appropriate.
The application of the same measurand in a different location or by a different user, all other conditions being the same, shall result in the close agreement of successive measurements. The difference between the measurement results shall be small when compared with the MPE.
The application of the same measurand under the same conditions of measurement shall result in the close agreement of successive measurements. The difference between the measurement results shall be small when compared with the MPE.
A measuring instrument shall be sufficiently sensitive and the discrimination threshold shall be sufficiently low for the intended measurement task.
A measuring instrument shall be designed to maintain an adequate stability of its metrological characteristics over a period of time estimated by the manufacturer, provided that it is properly installed, maintained and used according to the manufacturer's instruction when in the environmental conditions for which it is intended.
A measuring instrument shall be designed to reduce as far as possible the effect of a defect that would lead to an inaccurate measurement result, unless the presence of such a defect is obvious.
When a measuring instrument has associated software which provides other functions besides the measuring function, the software that is critical for the metrological characteristics shall be identifiable and shall not be inadmissibly influenced by the associated software.
Software identification shall be easily provided by the measuring instrument.
Evidence of an intervention shall be available for a reasonable period of time.

The relevant requirements of Annex I, the specific requirements of this Annex and the conformity assessment procedures listed in this Annex, apply to exhaust gas analysers defined below intended for inspection and professional maintenance of motor vehicles in use.
An exhaust gas analyser is a measuring instrument that serves to determine the volume fractions of specified components of the exhaust gas of a motor vehicle engine with spark ignition at the moisture level of the sample analysed.
These gas components are carbon monoxide (CO), carbon dioxide (CO2), oxygen (O2) and hydrocarbons (HC).
The content of hydrocarbons has to be expressed as concentration of n-hexane (C6H14), measured with near-infrared absorption techniques.
The volume fractions of the gas components are expressed as a percentage (% vol) for CO, CO2 and O2 and in parts per million (ppm vol).
Moreover, an exhaust gas analyser calculates the lambda value from the volume fractions of the components of the exhaust gas.
Lambda is a dimensionless value representative of the burning efficiency of an engine in terms of air/fuel ratio in the exhaust gases. It is determined with a reference standardised formula.
