1. Scope
This part of GB 2099 applies to plugs and fixed or portable socket-outlets for a.c. only, with or without earthing contact, with a rated voltage greater than 50 V but not exceeding 440 V and a rated current not exceeding 32 A, intended for household and similar purposes, either indoors or outdoors.
The rated current is limited to 16 A maximum for fixed socket-outlets provided with screwless terminals.
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.
NOTE 1: General requirements for mounting boxes are given in GB 17466.
This standard also applies to plugs incorporated in cord sets, to plugs and portable socket -outlets incorporated in cord extension sets and to plugs and socket-outlets which are a component of an appliance, unless otherwise stated in the standard for the relevant appliance.
This standard does not apply to
--plugs, socket-outlets and couplers for industrial purposes;
--appliance couplers;
--plugs, fixed and portable socket-outlets for ELV;
NOTE 2: ELV values are specified in GB 16895.21.
--fixed socket-outlets combined with fuses, automatic switches, etc.
NOTE 3: Socket-outlets with pilot lights are allowed provided that pilot lights comply with the relevant standard, if any.
Plugs and fixed socket-outlets complying with this part are suitable for use at ambient temperatures not normally exceeding 35 °C, but occasionally reaching 40 °C1).
1）Considering the climate and geographic situation of China, so it specified that the ambient temperatures of plugs and fixed socket-outlets are not normally exceeding 35 °C, but occasionally reaching 40 °C." In this article of IEC 60884-1: 2006, it specifies "Plugs and fixed or portable ocket-outlets complying with this standard are suitable for use at ambient temperatures not normally exceeding 25 °C, but occasionally reaching 35 °C." According to the same reasons, the test temperature of thermoplastic or elastomeric material in article 10.1 is changed to (40±2) °C.(It is specified as (35±2) °C in IEC 60884-1.)
NOTE 4 Socket-outlets complying with this part 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 40 °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.
