Compliance overview
Scope and applicability
This standard applies to industrial explosives, specifying their classification, basic requirements, technical specifications, and testing methods. It is crucial for manufacturers and importers of industrial explosives in China. This standard does not apply to industrial explosives containing gunpowder. It replaces the previous versions GB 28286-2012 and GB 14493-2003.
Technical requirements
The standard outlines the basic requirements for industrial explosives, including composition, thermal stability, and performance parameters like density, detonation velocity, and brisance, which must be defined by the manufacturer's technical documents. It introduces a new classification system based on composition and detonator sensitivity (with or without detonator sensitivity). It specifies strict safety performance criteria, including limits on mechanical sensitivity (impact and friction), thermal sensitivity, and anti-deflagration properties. For coal mine permissible explosives, specific requirements for combustible gas safety and coal dust-combustible gas safety are mandated across three safety levels. Manufacturers must ensure their products meet these mandatory safety thresholds to be compliant. Additionally, the standard regulates toxic gas content generated after detonation, setting different limits for explosives used in tunnel engineering versus non-tunnel applications. Quality assurance periods are also defined, varying from 7 days for site-mixed explosives to 120 days for those with detonator sensitivity.
Testing methods
The standard references various national and industry-standard testing methods to verify compliance. Key tests include thermal stability testing (WJ/T 9054), friction and impact sensitivity tests (WJ/T 9052.1 and WJ/T 9052.2), and toxic gas content determination (GB/T 18098). For coal mine permissible explosives, combustible gas safety (GB/T 18097) and anti-deflagration tests (GB/T 20061) are required. Manufacturers must conduct both factory and type inspections to ensure ongoing compliance.
FAQs
What products are regulated under GB 28286-2024?
GB 28286-2024 regulates industrial explosives, including water-based explosives and ammonium nitrate fuel oil (ANFO) explosives. It does not apply to industrial explosives containing gunpowder.
Are there any updates from the previous version of GB 28286?
Yes, this version merges and replaces GB 28286-2012 and GB 14493-2003. Key updates include the addition of terms and definitions, new classification methods based on composition and detonator sensitivity, and new requirements for toxic gas content in non-tunnel applications.
What are the packaging and marking requirements under this standard?
The standard requires that packaging materials be moisture-proof, compatible with the explosive, and sufficiently strong. Markings must include product name, manufacturer details, hazard symbols per GB 190, and specific safety warnings. Coal mine permissible explosives must also have a safety mark.
