Inspectors’ Class 3 standard means a reference standard of measurement that has been verified in accordance with regulation 13 and that complies with the requirements of regulations 29 and 34 for the maximum permissible uncertainty and the maximum permissible variation of an Inspectors’ Class 3 standard.
[3]           Regulation 3, definition of maximum permissible error
substitute
maximum permissible error, for a material measure or measuring instrument, means the maximum limit of error that:
                (a)    if a certificate is issued on or after 1 July 2007 for the material measure or measuring instrument — is mentioned in the certificate; or
               (b)    otherwise — is mentioned in Schedule 12 for a material measure or measuring instrument of that kind.
[4]           Regulation 3, after definition of maximum permissible error
insert
recertification, for a measuring instrument or reference material, means certification of the instrument or material after the initial certification of the instrument or material.

[5]           Regulation 3, after definition of SI
insert
State secondary standard means a reference standard of measurement that has been verified in accordance with regulation 13 and that complies with the requirements of regulation 25 for the maximum permissible uncertainty of a State secondary standard.
State tertiary standard means a reference standard of measurement that has been verified in accordance with regulation 13 and that complies with the requirements of regulation 26 for the maximum permissible uncertainty of a State tertiary standard.
[6]           Regulation 3, after definition of time
insert
variant means a change made to the pattern of an instrument, subject to the arrangement of the components of the instrument and the measuring element being substantially of the same design as that of the approved pattern.
[7]           Regulation 3, definition of verification
substitute
verification means:
                (a)    for a standard of measurement — verification of the standard under regulation 13; and

        4       However, whatever the measured quantity may be, the magnitude of the maximum permissible error is the greater of the following 2 values:
                (a)    the absolute value of the maximum permissible error in table 5 or table 6;
    (b)    the minimum specified volume deviation under clause 5.
        5       For minimum measured quantities equal to or greater than 2 L, the minimum specified volume deviation (Emin) is calculated using the formula:
where:
Vmin is the minimum measured quantity.
A is the maximum permissible error specified in the column headed ‘A’ of table 5 for the accuracy class of the measuring system.
        6       For minimum measured quantities less than 2 L, the minimum specified volume deviation is twice the value set out in table 6 and related to the column headed ‘A’ in table 5.
Note   The minimum specified volume deviation is an absolute maximum permissible error.
Accuracy of associated measuring instruments
        7       Associated measuring instruments must exhibit an accuracy at least as good as the values set out in tables 7A, 7B and 7C for the accuracy class of the measuring system.
