This document adopts the re-drafting method for the modification and adoption of IEC 60884-
1:2013 Plugs and Socket-outlets for Household and Similar Purposes - Part 1: General
Requirements.
In comparison with IEC 60884-1:2013, this document has some structural adjustments. In order
to avoid suspended paragraphs, the numbering of clauses 10.2, 14.10, 14.23, Chapter 17,
Chapter 19, Chapter 22, Chapter 24, Chapter 25, 28.1 and Chapter 30 is adjusted; due to the
existence of second-level clauses, the clause titles of the first-level clauses in Chapter 10,
Chapter 13, Chapter 14 and Chapter 24 are added.
The technical differences between this document and IEC 60884-1:2013, and the causes for
these differences are as follows:
---In terms of Normative References, this document makes adjustments with technical
differences, so as to adapt to the technical conditions of China. The adjustments are
intensively reflected in Chapter 2 “Normative References”. See the specific
adjustments below:
 GB/T 2423.4, which equivalently adopts international standard, is used to replace
IEC 60668-2-30;
 GB/T 2423.7, which equivalently adopts international standard, is used to replace
IEC 60668-2-31;
 GB/T 2423.55, which equivalently adopts international standard, is used to replace
IEC 60668-2-75;
Plugs and Socket-outlets for Household and Similar
Purposes - Part 1: General Requirements
1 Scope
This document specifies the technical requirements for the marking, electric-shock protection,
structure, electrical performance and mechanical performance of plugs and socket-outlets for
household and similar purposes.
This document 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 document 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.
