After the disturbance the meter shall overcome the degradation or loss of function, and the accuracy must not be more affected that which is appropriate considering the State of the art.

6 fit the transformer must be designed so that it can be connected to a meter that meets the requirements of this order and who has been legally on the market or who will be imminent.

7 designation 7.1 all data necessary for the identification and characterization of the transformer must appear on the way clear, indelible transformer and intransferable.7.2 the transformer connection points must be indicated sustainably and unequivocal.

Annex 4 (art. 6, para. 3) Procedure of statistical control for electricity meter has Definitions 1. Lot: the number of homogeneous meters which is controlled through the statistical control procedure.
2. sample: the subset of a lot that is chosen to be controlled by survey.

B requirements for batch counters gathered to train a lot according to the following criteria: 1 a batch can count maximum 5000 compteurs.2 a batch can only contain counters of the same type, with the same accuracy class and the same operating range, from two production years at most. Counters of two consecutive years of manufacture are allowed only when the number of meters of the batch manufactured in one of the two years is not superior to 1000.3 combinations of different counters are not allowed within the same batch. Only are permitted differences of little importance which cannot have any influence on the result of the control of an echantillon.4 a batch can contain counters belonging to multiple users. All users within a batch are concerned in solidarity by the result of control by sampling and possible measures. The commitments referred to in the let. D, c. 5, cannot be honored that with the consent of all the utilisateurs.5 METAS issues directives establishing the administrative procedures for controls in particular announcement, the designation and management changes in batches, as well as the organisation of controls by sampling and the announcement of the results.

C Preparation of control by sampling 1 user who wants to announce new counters for the statistical control procedure must do until 30 June of the fourth year following the production of the majority of the counters announced. The first control by sampling takes place five years after the year of manufacture of the majority of counters contained in the batch. Subsequently, checks by sampling are performed all five years.2 the prizes are administered by METAS or by a verification laboratory authorized. METAS or authorized verification lab pulls samples, based on the lists of lots, in the second half of the year that precedes the control by sampling. If the batch is administered by a verification laboratory authorized it shall submit the list of the lot to METAS. The draw of the samples must be carried out according to a procedure approved by METAS. Are from two samples of 46 meters per sample, which used six sample meters of reserve. Reserve counters cannot be controlled in the exceptional cases defined in the let. E, ch. 2 and 3.3 user must make available the first sample in the four months from the notification of the drawing of samples. The second sample should, insofar as this is necessary according to the let. D, point 3, be made available within two months of the notification of the results of the first sample control. If the user decides to make available the second sample regardless of the results of the first sample control, he must make available two samples within six months from the notification of the drawing of samples.

D requirements for samples 1 initially, METAS or a verification laboratory authorized control 40 meters of the first sample. The requirements applicable to samples are considered as met if up a counter don't filled not the requirements defined in appendices 1 and 2.2 If more than four meters of the first sample do not meet the requirements set out in annexes 1 and 2, all counters of the lot must be decommissioned according to the Let's. F, ch. 2.3 If two, three or four meters of the first sample do not meet the requirements, the 40 meters of the second sample are also controlled. If more than four meters from the two samples do not meet the requirements set out in annexes 1 and 2, all counters of the lot must be decommissioned according to the let. F, ch. 2.4 METAS may order controls and further investigations if deviations from the normal behavior of the counters are suspected, including if we suppose for certain types, some years of construction or certain lots to sample counters are not representative for all counters in service of the lot concerned. METAS can exclude certain types, years of construction or lots of control statistique.5 procedure it can be waived enforcement of controls according to points 1 and 3 when the user undertakes, within the time limits for the provision of meters according to the Let's. C, point 3, to decommission all counters of the batch concerned according to the let. F, ch. 2.

E Execution of the control sample 1 sample counters are controlled at the plombe.2 State counters with obvious signs of deterioration do not need to be controlled. However, they must be reported to METAS by indicating the nature of the deterioration. METAS can authorize the use of reserve counters. Are not regarded as obvious detectable damage by laymen without auxiliary means or disassembly of parts such as fire damage, water damage, sustainable electronic breakdown or defect reported by the meter in such a way that a layman can catch without prior knowledge of the operating instructions.
3. If a meter is not found or not removable user must report to the verification laboratory authorized address of installation of the meter. If the corresponding prize is administered by METAS the meter must be reported to METAS. METAS may fix, for a particular case, how a counter not found or not removable is counted when evaluating defined in the let. D, c. 1 to 3. It can allow the use of reserve counters.
4. controls must be completed at the latest at the end of October of the year of the control. If the batch is administered by a verification laboratory authorized this passes the results of the check to METAS immediately after the control of the echantillon.5 within a period of two months from the receipt of the results of the control, METAS decides to the rest of the procedure. Until the release of the batch by METAS, any intervention on the counters of the sample is prohibited and lead sealing of the sample counters must not be broken. During this period, counters remain at the disposal of METAS. METAS can proceed with further investigations either by sending a verification laboratory, either running them himself. 6 If the sample met the requirements, the batch is released by METAS insofar as controls where possible and additional investigations according to the let. D, CH 4 did not identify the type, the years of construction represented in the lot or the lot should be excluded from the statistical control procedure. The release is done by ecrit.7 the sample meters which do not meet the requirements must be repaired or removed from the circulation.8 user can revise counters belonging to lots existing with a METAS authorization and that on the basis of a program approved by METAS.

F checking validity


1. If METAS frees the batch in accordance with the let. E, ch. 6, released batch counters are regarded as verified for the next five years, insofar as they are still subject to the procedure of control statistique.2 when samples do not meet the requirements or when it is renounced control referred to the let. D, c. 5, all counters of the batch concerned must be taken out of service until the end of the year following the year of the control to the most tard.3 a new market of counters removed from circulation requires an audit according to annex 7, ch. 1, OIMes.4 for counters that despite the extension of the validity of their verification according to section 1 must be replaced or which batches are deleted METAS can decide, at the request of the user, these counters are regarded as verified for a maximum period of five years. These counters can no longer be allowed in the statistical control procedure.

G equivalent Procedures METAS can in special cases to order or approve other procedures statistically at least equivalent.
