5 Verification method
5.1 Introduction
5.1.1 This verification procedure defines methods and tools of primary and periodic verifi-
cation procedure of the X-Ray and Gamma Personal Dosimeters РМ1610, РМ1610А, РМ1610В,
РМ1610-01, РМ1610А-01, РМ1610В-01 (further – instruments).
5.1.2 Produced instruments and instruments repaired because of non-compliance of metro-
logical performance with specification requirements are subject to primary verification.
Instruments in operation are subject to periodic verification.
5.1.3 Exceptional verification is carried out before the verification period termination if:
- the instrument was repaired;
- it is necessary to validate the instrument operability;
- the instrument was put into operation, sold or rented after the half verification peri-
od termination.
Exceptional verification procedure for the instrument after repair is determined by the initial
verification procedure.
5.1.4 Verification is carried out by local state metrological services according to current
standards, or by authorized companies.
Verification frequency of instruments in use − 12 months.
