Schedule 1 Amendments
(section 3)
[1] Paragraph 5.6 (b)
substitute
(b) electricity meters installed before 1 January 2013;

[2] Paragraph 5.6 (d)
substitute
(d) water meters installed on or after 1 July 2004, other than cold water meters with a maximum continuous flow rate capacity of not more than 4 000 litres per hour.
[3] Schedule 1, Part 3, Division 2, clause 1
substitute
1 For in‑service inspection of instruments with digital indication, add 0.5 scale interval to the maximum permissible error for in‑service inspection that applies to an analog instrument.
1A However, item 1 does not apply to an instrument with digital indication if the scale interval for the instrument is less than or equal to 0.2 dm2.
[4] Schedule 1, Part 3, Division 6, clause 5
substitute
5 The maximum permissible error for any load equal to or greater than the minimum capacity and equal to or less than the maximum capacity in automatic operation is:
(a) if the national instrument test procedures that apply to catch weighers eliminate the need for digital rounding—the maximum permissible error set out in table 13 minus a verification scale interval of 0.5 e; or
(b) in any other case—set out in table 13.
Note The national instrument test procedures are defined in the Act and are available at www.nmi.gov.au.

Division 12 Electricity meters
1 In this Division:
Ib, for an electricity meter of a kind mentioned in clause 3, is the basic current.
Imax, for an electricity meter of a kind mentioned in clause 3 or 4, is the maximum current.
In, for an electricity meter of a kind mentioned in clause 4, is the nominal current.
Accuracy classes
2 Electricity meters are classified into the following accuracy classes:
(a) 0.2;
(b) 0.5;
(c) 1;
(d) 1.5.
Maximum permissible errors—direct‑connected electricity meters
