The core cycle for explosion-proof electrical testing is3-year inspectionBased on the national standards AQ 3009-2007 and GB/T 3836 series, inspections must be conducted by institutions with professional qualifications.
Section 1: Explosion-Proof Electrical Equipment Inspection Cycle
Mandatory Testing Requirements：
- Professional Inspection CycleWithin 3 years, in accordance with Clause 5.2.4 of AQ 3009-2007.
- Routine InspectionInitiated independently by the company, the project is completed in less than three years.
2. Special Circumstances：
- High-temperature/corrosive environments require shortened cycles.
- Equipment must be re-inspected after改造.
Section 2: National Standard for Explosion-Proof Electrical Equipment Testing
1. Core Standard System：
- AQ 3009-2007Electrical Explosion Protection Safety Regulations for Hazardous Areas
