Champ d’application

This standard applies to the inspection of hazardous properties for solid inorganic nitrates (excluding ammonium nitrate) classified as dangerous goods. It covers the terms, requirements, testing, marking, and inspection rules for these materials. Manufacturers and shippers of inorganic nitrate compounds must comply with this standard to ensure safe transport.

Exigences techniques

The standard outlines the physical preparation and environmental conditions for testing oxidizing solids. It mandates checking particle size distribution, requiring grinding if powders under 500μm exceed 10% of the mass. Tests must be conducted at ambient temperature (20°C±5°C) with controlled ventilation. Furthermore, it specifies strict storage and handling protocols, requiring segregation from organic combustibles and protection from heat and friction. Packaging must bear accurate markings and hazard labels compliant with GB 19458-2004.

Méthodes d’essai

The core evaluation is the oxidizing solid test, which compares the burning rate of the nitrate sample mixed with cellulose against a reference mixture of potassium bromate and cellulose. The procedure utilizes an inert metal wire ignition source and a low thermal conductivity plate. Results determine classification under Division 5.1 and assign the appropriate packing group (I, II, or III).
