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/T 14372-2013 "Test methods and criteria for explosives in the transport of dangerous goods" and is in line with GB/T 14372- Compared with.2013, in addition to structural adjustments and editorial changes, the main technical content changes are as follows:

--- Added the 75°C simulated stack spontaneous combustion temperature (SBAT) thermal stability test in the third group of test items (see 6.5.2);

--- Added brittleness test in test group 7 (see 10.3.2);

--- Added the minimum self-sustaining combustion pressure (MBP) test in the eighth test group (see 11.5);

--- Added Group 9 burning rate test (external flame) items (see Chapter 12). Please note that some of the contents of this document may involve patents.

---This is the third revision. Dangerous goods Approval and test methods for explosives Warning. The person using this document should have practical experience in regular laboratory work. Special attention should be paid to the test process involving explosions. The use of products requires relevant qualifications and site conditions or entrusting the operation to a unit with relevant conditions. This document does not indicate all possible For safety issues, users are responsible for taking appropriate safety and health measures.

1 Scope

GB/T 14372-2024 specifies the test methods by which a substance or article is accepted into Class 1 of the dangerous goods classification and assigned to a division within it. This is the Chinese implementation of the UN test series 1 to 8, and it is the gateway to the whole transport regime for explosives: whether something is an explosive at all, whether it is too dangerous to transport in any form, which of the six divisions it belongs to, and which compatibility group. The consequences are commercial as much as regulatory, since a division 1.1 assignment and a division 1.4 assignment for the same article mean entirely different packaging, quantity limits, vehicle requirements and routes. The standard sets out the test series, the apparatus and the procedure for each test, the criteria by which the result is interpreted, and the decision logic that leads from the results to the classification. The 2024 edition replaces GB/T 14372-2013. For an explosives maker, a fireworks or airbag propellant producer, or an authority in China, this is the classification text.

This document specifies the tests required for the approval and classification of explosives and desensitized explosives (explosives and desensitized explosives specified in GB 14371) Principle of the method, instruments and materials, test conditions, test procedures and presentation of results. This document applies to the approval and sub-item testing of explosives and desensitized explosives.
