scope:

This part 2-4 of IEC 60884 applies to plugs, fixed or portable socket-outlets, and to socketoutlets for appliances from 6 V up to and including 48 V d.c. or a.c. (50/60 Hz) SELV with rated current of 16 A, intended for household and similar purposes, either indoors or outdoors.

NOTE 1 The extension of this standard to higher frequencies is under consideration.

This standard does not cover requirements for flush mounting boxes: however, it covers only those requirements for surface-type mounting boxes which are necessary for the tests on the socket-outlet.

This standard also applies to plugs and socket-outlets incorporated in cord sets integrated or incorporated in appliances or intended to be fixed to them.

NOTE 2 A socket-outlet integrated in an appliance or equipment is a socket-outlet which is formed by the housing of the appliance or equipment.

A socket-outlet incorporated in an appliance or equipment is a separate socket-outlet built in or fixed to an appliance or equipment.

Socket-outlets for appliances or equipment shall comply with IEC 60884-2-2.

This standard does not apply to

- plugs, socket-outlets and couplers for industrial purposes;

- appliance couplers;

- fixed socket-outlets combined with fuses, automatic switches, etc.

Plugs and fixed or portable socket-outlets complying with this standard are suitable for use at ambient temperatures not normally exceeding 25 °C, but occasionally reaching 35 °C.

NOTE 3 Socket-outlets complying with this standard are only suitable for incorporation in equipment in such a way and in such a place that it is unlikely that the surrounding temperature exceeds 35 °C.

In locations where special conditions prevail, such as in ships, vehicles and the like, and in hazardous locations, for example where explosions are liable to occur, special constructions may be required.
