Foreword

The purpose of this document is to achieve the optimum balance among the safety levels of human beings, the environment and products, so that the electric equipment can minimize the risks of damage to life, health and property during product design, manufacture, sales and usage, and achieve an acceptable level. This document provides information on the basic safety requirements for various types of electric equipment products. National Technical Specification for the Safety of Electric Equipment

1 Scope

GB 19517-2023 is the Chinese national standard on national technical specification for the safety of electric equipments, in the field of electrical engineering. 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 23 May 2023 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 June 2024. Classification: ICS 29.020, CCS K09. 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.

This document specifies the basic safety requirements for various types of hand-held, movable and fixed electric equipment for indoor and outdoor application with a rated AC voltage below 1,000 V (1,140 V) and a rated DC voltage below 1,500 V (hereinafter referred to as "the products"). This document is applicable to products or components within the application range of electric energy converted from chemical energy, light energy and wind energy, etc. Products with internally generated inaccessible AC voltages higher than 1,000 V and DC voltages higher than 1,500 V also fall within the scope of application of this document. This document does not apply to.
