Specifies requirements for the construction and performance of induction watthour meters fitted with demand registers to indicate maximum demand. This Standard is to be read in conjunction with AS 1284.1.

This Standard specifies requirements for 50 Hz a.c. induction watthour meters provided with a demand register to indicate maximum demand. This Standard does not apply to meters that record demand or to meters that depend upon thermal effects or are operated by pulses.
