Certificates of verification of State primary standards of measurement(1) When a State primary standard of measurement is verified, a certificate of verification must be issued to the appropriate State authority.
(2) The certificate of verification of a State primary standard of measurement must state:
(a) that it verifies the State primary standard of measurement in an appropriate manner, having regard to the nature of the standard of measurement; and
(b) the date of verification; and
(c) the value ascertained for the standard on that date in terms of an Australian legal unit of measurement; and
(d) the accuracy with which the standard is verified; and
(e) the value (stating the uncertainty) of any relevant environmental or other influence factors, like temperature and pressure, at the time of the verification; and
(f) a description of any mark on, or attached to, the standard under these regulations; and
(g) the period, from the date of verification, for which the certificate is given.
(4) 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.

(a) 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
(b) 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
(c) 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.
