Compliance overview
Scope and applicability
This standard applies to the classification, technical requirements, testing, and packaging of industrial electric blasting caps. It specifically covers ordinary electric detonators, coal mine permitted electric detonators, and seismic exploration electric detonators. Manufacturers and exporters of civil blasting equipment must comply with these regulations.
Technical requirements
The standard specifies comprehensive physical and electrical parameters for detonators. It mandates strict criteria for leg wire integrity, including minimum insulation thickness and high-voltage breakdown performance. Material restrictions prohibit paper shells and aluminum alloys for coal mine use. Key electrical safety metrics like maximum non-firing current and electrostatic sensitivity are strictly regulated. Performance requirements cover seismic resistance, detonating capability, tensile strength, and water resistance under specific pressure conditions. The standard also defines thermal stability at elevated temperatures and flammable gas safety for coal mine applications. Delay time series are categorized into millisecond and second intervals with strict upper and lower specification limits.
Testing methods
Testing procedures include visual inspection, resistance measurement, and vibration testing to ensure structural integrity. Detonating capability is verified via lead plate penetration tests, while water resistance is evaluated through pressurized submersion. Specific methodologies for electrostatic sensitivity and delay time measurement are detailed in referenced standards like WJ/T 9042 and GB/T 13225.
