Escopo e aplicabilidade

This standard is applicable to the inspection of hazardous properties for civil explosives dangerous goods. It specifically regulates classification, requirements, testing, codes, and labeling. This standard is mandatory for all manufacturers and exporters of civil explosives entering the Chinese market. It does not apply to military explosives, explosives in the production process, or hazards caused by electrostatic or electromagnetic fields.

Requisitos técnicos

The standard specifies the classification of civil explosives into 6 hazard divisions (Division 1.1 to 1.6) and 13 compatibility groups (A to S, excluding I). It mandates that any substance or article with explosive properties must be assigned an appropriate classification code. Manufacturers must provide a hazardous classification and inspection report from a recognized institution for first-time transport, production, or export. The standard also details strict compatibility and stowage requirements, noting that goods in the same classification code can generally be assembled together, with specific exceptions for Compatibility Group L. Furthermore, it outlines the procedures for determining if a substance is too sensitive or thermally unstable for transport.

Métodos de ensaio

The standard establishes a comprehensive testing procedure divided into 7 test series to determine the classification and compatibility group of explosives. Key tests include Test Series 3 (impact sensitivity using the BAM fall hammer, friction sensitivity, and thermal stability at 75°C) and Test Series 4 (thermal stability of articles and 12m drop tests). Testing must follow the specific procedural order outlined in the normative appendices to accurately determine the hazard division. Other test series reference the UN Manual of Tests and Criteria for external fire tests, detonation transitions, and extremely insensitive detonating substances.

Perguntas frequentes

What products are regulated under GB 19455-2004?

The standard regulates the inspection of hazardous properties for civil explosives. It does not apply to military explosives, explosives in the production process, unpackaged explosive substances, or hazards caused by electrostatic, electromagnetic fields, or improper operation.

How does GB 19455-2004 relate to international standards?

The standard is based on the UN Recommendations on the Transport of Dangerous Goods (Model Regulations and Tests and Criteria Manual). It aligns technically with these international frameworks but is non-equivalent in its editorial formatting. It is mandatory for relevant manufacturers and exporters.

What testing procedures are required for classification under this standard?

Testing is divided into 7 series to determine classification and compatibility. Key tests include impact sensitivity, friction sensitivity, thermal stability at 75°C, and various external fire and drop tests, referencing the UN Manual of Tests and Criteria.
