Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part

1.Structure and drafting rules for standardization documents" Drafting. This document replaces GB 19417-2003 "Detonating Cord Detonators". Compared with GB 19417-2003, except for structural adjustments and editorial changes, In addition, the main technical changes are as follows:

--- Changed the scope (see Chapter 1, Chapter 1 of the.2003 edition);

--- Added applicable terms and definitions (see Chapter 3);

--- Changed the classification and nomenclature (see 4.1, 4.2, Chapter 3 of the.2003 edition);

--- Added requirements for the material and identity information of industrial detonators (see 5.1, 5.2);

--- Changed the description of appearance requirements (see 6.1,

4.1 of the.2003 edition);

--- Deleted the requirements for the length of the detonating tube (see

4.2 of the.2003 edition);

--- Added requirements for the insulation performance of industrial electric detonators and industrial electronic detonator leg wires (see 6.2);

--- Added the requirements for the maximum non-ignition current of industrial electric detonators (see 6.3);

--- Added electrostatic sensitivity of industrial electric detonators and industrial electronic detonators (see 6.4);

--- Changed the requirements for seismic resistance and tensile resistance (see 6.5, 6.6, 4.3.1,

1 Scope

GB 19417-2025 is the Chinese national standard on general safety and technology requirements of commercial detonator, in the field of chemical technology. 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 30 May 2025 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 June 2026. Classification: ICS 71.100.30, CCS G 89. 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 gives the classification and nomenclature of industrial detonators, specifies safety technical requirements, inspection rules, marking (identification) and packaging, and describes the test Test method. This document applies to the scientific research, production, testing and acceptance of industrial detonators. This document is not applicable to industrial detonators for oil and gas wells or other special ranges.
