National Measurement Regulations 1999

An Australian primary or secondary, or a State primary, standard of measurement must bear an identifying mark before it is verified.

Immediately after verifying an Australian primary or secondary, or a State primary, standard of measurement, the Chief Metrologist must mark the standard with a statement of the date of verification of the standard.

A mark mentioned in subregulation (1), (2) or 13(4) or regulation 15 must be:

legible; and

on, or attached to, the standard:

permanently; or

in such a way that the mark cannot be obliterated or removed without being destroyed.

However, if compliance with subregulation (3) is impracticable because of the nature, shape or size of a standard of measurement, the standard is taken to comply with subregulation (3) if it is enclosed in a sealed container that is marked in accordance with subregulation (3).
