Foreword

This document conforms to GB/T 1.1-2020 "Standardization Work Guidelines Part

1.Structure and Drafting Rules of Standardization Documents". Drafting is scheduled. This document replaces GB 23757-2009 "Requirements for Protection of Electronic Products in Fire Protection". Compared with GB 23757-2009, the main differences are structural adjustments and... Aside from editorial changes, the main technical changes are as follows:

a) The normal operating environment has been improved (see 4.2);

b) Special usage environments have been added (see 4.3);

c) Added normal monitoring status (see 4.4);

d) The strength requirements for materials and components have been changed (see 5.1,

3.2.2 in the.2009 edition).

e) Terminal requirements have been changed (see 5.2,

3.2.3 of the.2009 edition);

f) The protective grounding requirements have been changed (see 5.3,

3.2.4 of the.2009 edition).

g) Added product requirements applicable to normal use environments (see 6.1);

h) Added product requirements applicable to special use environments (see 6.2);

i) Increased temperature rise requirements (see 6.3);

1 Scope

GB 23757-2025 is the Chinese national standard on protection requirements for fire electronic products, in the field of environment and health protection, safety. It carries no /T suffix, which in the Chinese system means compliance is mandatory: a product or a practice within its scope has to meet it to be lawfully made, sold or carried out in China. It was issued on 5 October 2025 by the State Administration for Market Regulation; Standardization Administration of China, and takes effect on 1 November 2026. Classification: ICS 13.220.20, CCS C81. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.
