Regulations 2(1) and 14
1. The essential requirements are the relevant requirements relating to automatic discontinuous totalisers contained in Annex I and MI-006, as set out in this Schedule.U.K.
2. In this Schedule—
“climatic environments” means the conditions in which automatic discontinuous totalisers may be used;
“critical change value” means the value at which the change in the measurement result is considered undesirable;
“disturbance” means an influence quantity having a value within the limits specified in the appropriate requirement but outside the specified rated operating conditions of the automatic discontinuous totaliser. An influence quantity is a disturbance if for that influence quantity the rated operating conditions are not specified;
“influence quantity” means a quantity that is not the measurand but that affects the result of measurement;
“measurand” means the particular quantity subject to measurement;
“rated operating conditions” means the values for the mesurand and influence quantities making up the normal working conditions of an instrument; and
“totalisation scale interval” means the part of an automatic discontinuous totaliser which indicates the sum of all the loads weighed and discharged to bulk.
3.—(1) Under rated operating conditions and in the absence of a disturbance, the error of measurement shall not exceed the maximum permissible error (MPE) value as set out in paragraph 17.
(2) MPE is expressed as a bilateral value of the deviation from the true measurement value.
(3) Under rated operating conditions and in the presence of a disturbance, the performance requirement shall be as set out in paragraph 23.
(4) Where the automatic discontinuous totaliser 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.
(5) The manufacturer shall specify the climatic and electromagnetic environments in which the instrument is intended to be used, power supply and other influence quantities likely to affect its accuracy, taking account of the requirements in this Schedule.
(a)Climatic environments—
The manufacturer shall specify the temperature range. The minimum temperature range is 30°C and shall be within the upper temperature limit of 70°C and the lower temperature limit of –40°C. The manufacturer shall indicate whether the automatic discontinuous totaliser is designed for condensing or non-condensing humidity as well as the intended location for the instrument, i.e. open or closed.
(b)Electromagnetic environments
(i)Electromagnetic environments are classified into classes E1 or E2 as follows—
E1 This class applies to automatic discontinuous totalisers used in locations with electromagnetic disturbances corresponding to those likely to be found in residential, commercial and light industrial buildings.
E2 This class applies to instruments used in locations with electromagnetic disturbances corresponding to those likely to be found in other industrial buildings.
(ii)The following influence quantities shall be considered in relation with electromagnetic environments—
(aa)voltage interruptions,
(bb)short voltage reductions,
(cc)voltage transients on supply lines and/or signal lines,
(dd)electrostatic discharges,
(ee)radio frequency electromagnetic fields,
(ff)conducted radio frequency electromagnetic fields on supply lines and/or signal lines;
(gg)surges on supply lines and/or signal lines.
(6) Other influence quantities to be considered, where appropriate, are—
(a)voltage variation,
(b)mains frequency variation,
(c)power frequency magnetic fields,
(d)any other quantity likely to influence in a significant way the accuracy of the instrument.
(7) When carrying out the tests as envisaged in these Regulations, the following paragraphs apply:
(a)Basic rules for testing and the determination of errors —
(i)Essential requirements specified in paragraphs (1) to (4) shall be verified for each relevant influence quantity. 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.
(ii)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.
(b)Ambient humidity
(i)According to the climatic operating environment in which the automatic discontinuous totaliser is intended to be used either the damp heat-steady state (non-condensing) or damp heat cyclic (condensing) test may be appropriate.
(ii)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.
4. 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.
5. 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.
6. An automatic discontinuous totaliser shall be sufficiently sensitive and the discrimination threshold shall be sufficiently low for the intended measurement task.
7. An automatic discontinuous totaliser 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.
8. An automatic discontinuous totaliser 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.
9.—(1) An automatic discontinuous totaliser shall have no feature likely to facilitate fraudulent use, whereas possibilities for unintentional misuse shall be minimal.
(2) An automatic discontinuous totaliser shall be suitable for its intended use taking account of the practical working conditions and shall not require unreasonable demands of the user in order to obtain a correct measurement result.
(3) Where an automatic discontinuous totaliser is designed for the measurement of values of the measurand that are constant over time, the instrument shall be insensitive to small fluctuations of the value of the measurand, or shall take appropriate action.
(4) An automatic discontinuous totaliser shall be robust and its materials of construction shall be suitable for the conditions in which it is intended to be used.
(5) An automatic discontinuous totaliser shall be designed so as to allow the control of the measuring tasks after the instrument has been placed on the market and put into use. If necessary, special equipment or software for this control shall be part of the instrument. The test procedure shall be described in the operation manual.
(6) When an 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.
(7) Means shall be provided to limit the effects of tilt, loading and rate of operation such that MPEs are not exceeded in normal operation.
(8) Adequate material handling facilities shall be provided to enable the instrument to respect the MPE during normal operation.
(9) Any operator control interface shall be clear and effective.
(10) The integrity of the display (where present) shall be verifiable by the operator.
