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; it covers only those
requirements for surface-type mounting boxes which are necessary for the tests on the socketoutlet.
This standard also applies to plugs and socket-outlets incorporated in cord extension sets or
integrated in 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.
In addition, socket-outlets for appliances or equipment must 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.
