National Measurement Regulations 1999

When a State primary standard of measurement is verified, a certificate of verification must be issued to the appropriate State authority.

The certificate of verification of a State primary standard of measurement must state:

that it verifies the State primary standard of measurement in an appropriate manner, having regard to the nature of the standard of measurement; and

the date of verification; and

the value ascertained for the standard on that date in terms of an Australian legal unit of measurement; and

the accuracy with which the standard is verified; and

the value (stating the uncertainty) of any relevant environmental or other influence factors, like temperature and pressure, at the time of the verification; and

a description of any mark on, or attached to, the standard under these regulations; and

the period, from the date of verification, for which the certificate is given.

For paragraph (2)(d), the accuracy of a State primary standard of measurement must be ascertained in a manner determined in writing by the Chief Metrologist.

For paragraph (2)(d), the accuracy with which a State primary standard of measurement must be verified must be expressed as an uncertainty that does not exceed:

for a standard for the measurement of length of a denomination stated in column 1 in Schedule 4—the maximum permissible uncertainty stated for the denomination in column 2 in that Schedule; or

for a standard for the measurement of mass of a denomination stated in column 1 in Schedule 5—the maximum permissible uncertainty stated for the denomination in column 2 in that Schedule; or

for a standard for the measurement of mass of a denomination not stated in column 1 in Schedule 5—the maximum permissible uncertainty appropriate to that denomination when linear interpolation is applied to the maximum permissible uncertainty stated for the denominations in column 2 in that Schedule.
