Specifies essential safety requirements for plugs and socket-outlets for approval and test purposes. It is intended to be read in conjunction with AS/NZS 3100.

This Standard specifies essential safety requirements for plugs and socket-outlets, as defined in Clause 1.4, intended for use at extra-low or low voltages and a rated current not exceeding 32 A for household or similar purposes. (For extra-low voltage plugs and socket-outlets, see Appendix E.)This Standard does not apply to the following: (a) Appliance couplers (see AS/NZS 3109.1).(b) Installation couplers (see AS/NZS 3131).(c) Plugs, socket-outlets and couplers for general industrial applications (see AS/NZS 3123).
