This document also applies to the in-service inspection of water meters.
 
This document does not apply to the re-verification of utility meters.
 
The National Measurement Act 1960 (Cth) (the Act) provides that national instrument test procedures (NITPs) are: the procedures for testing measuring instruments determined in writing by the Chief Metrologist under section 18GG of the Act; for use by verifiers of measuring instruments pattern approved for use for trade, i.e. trade measurement inspectors, servicing licenses and/or their employees and utility meter verifiers; the sole means by which compliance with the requirements for verification under section 18GK of the Act may be determined, i.e. that measuring instruments pattern approved for use for trade are operating within the prescribed maximum permissible errors (MPEs) or the MPEs stated in their Certificate of Approval; to be used in conjunction with reference standard of measurement such that the verification of a measuring instrument of a pattern approved for use for trade complies with the legal traceability imperatives of section 10 of the Act.
 
Note: NITPs are not in themselves a legislative instrument, however, under the Act failure to comply with their provisions may constitute grounds for disciplinary action against verifiers.
 
The Chief Metrologist of NMI has determined that NITP 14 contains the test procedures for the verification of utility meters.
This document: outlines procedures for the verification of utility meters including batch/lot sampling regimes for utility meters imported into Australia from other jurisdictions, as well as the production and issue of certificates of verification as a means of identifying verified imported utility meters in lieu of a verification mark; and stipulates the related provisions for utility meter verifiers appointed under section 18RA of the Act.
 
This document does not: mandate the pattern approval or verification of utility meters that are of a type and class exempt from the operation of the Act under regulation 5.6 of the National Trade Measurement Regulations 2009 (Cth); specify any requirements for gas meters; apply to the re-verification of utility meters.
