Compliance overview
Scope and applicability
This standard specifies the classification, decision logic, and labelling requirements for desensitized explosives. It applies to the classification and labelling of solid or liquid explosive substances and mixtures that have been desensitized to suppress their explosive properties, in accordance with the UN Globally Harmonized System (GHS). This standard is mandatory for manufacturers and suppliers handling desensitized explosives in China. It does not apply to substances with an exothermic decomposition energy of less than 300 J/g.
Technical requirements
GB 30000.30-2025 establishes the criteria for classifying desensitized explosives into four hazard categories based on their corrected burning rate (Ac). The standard requires that desensitized explosives must not produce actual explosive or pyrotechnic effects and must not have a mass explosion hazard when tested according to GB/T 14372-2024. For nitrocellulose mixtures, stability must be determined in accordance with GB/T 44184 before classification. The standard also details the labelling elements, including pictograms, signal words, and hazard statements. Categories 1 and 2 require the signal word "Danger", while Categories 3 and 4 require "Warning". The label must include specific hazard statements (e.g., H206, H207, H208) and precautionary statements covering general, prevention, emergency response, storage, and disposal measures. The allocation of these label elements is strictly defined in the normative appendices.
Testing methods
The classification process involves determining sensitivity, thermal stability, explosiveness, and corrected burning rate using methods specified in GB/T 14372-2024. The exothermic decomposition energy is measured using Differential Scanning Calorimetry (DSC) as described in the standard's appendix, referencing GB/T 22232. For mixtures containing nitrocellulose, the stability testing method outlined in GB/T 44184 must be utilized.
FAQs
What products are regulated under GB 30000.30-2025?
GB 30000.30-2025 regulates desensitized explosives, which are solid or liquid explosive substances or mixtures that have been treated (e.g., with water, alcohol, or other diluting agents) to suppress their explosive properties so they do not mass explode or burn rapidly.
How are desensitized explosives categorized in this standard?
They are categorized into four hazard classes based on their corrected burning rate (Ac) determined through the burning rate test in GB/T 14372-2024. The categories range from Category 1 (highest burning rate) to Category 4 (lowest burning rate).
Does GB 30000.30-2025 align with international standards?
Yes, the technical content of this standard is consistent with the UN Globally Harmonized System of Classification and Labelling of Chemicals (GHS), 10th revised edition, ensuring alignment with international chemical classification practices.
