The standards referenced in the "Electrical Explosion Proof Inspection Report" issued from regular inspections of explosion-proof electrical equipment include, but are not limited to:
GB 50058-2014 "Code for Design of Electrical Installations in Explosive Hazardous Environments"
GB50257-2014 Specification for Construction and Acceptance of Electrical Installations in Explosive and Fire Hazardous Environments
GB/T3836.15-2017 "Electrical Equipment for Explosive Gas Atmospheres — Part 15: Electrical Installations in Hazardous Areas (Excluding Mines)"
AQ3009-2007 Electrical Explosion-Proof Safety Regulations for Hazardous Areas

What certifications are required for regular inspections of explosion-proof electrical equipment?
The regular inspections of explosion-proof electrical equipment, as mentioned in the previous text and conducted according to the AQ 3009-2007 "Electrical Safety and Explosion-Proof Rules for Hazardous Areas" standard, must be carried out by a testing center with explosion-proof professional qualifications. This qualification is authorized by the CNAS on behalf of the government, and can be verified on the CNAS website.

Standard and Cycle for Regular Inspections of Explosion-Proof Electrical Equipment
As explosion-proof electrical appliances become more widespread, they are increasingly installed and used in many explosive hazard areas.
Many end-users believe that as long as explosion-proof electrical equipment is installed in explosive hazardous areas, everything is settled.
In many cases, so-called explosion-proof electrical appliances do not have a valid explosion-proof certification, or the certification has expired or is counterfeit. The label does not match the explosion-proof certification.
Inadequate explosion-proof type selection, mixed use of gas explosion-proof electrical equipment and dust explosion-proof electrical equipment, improper wiring for explosion-proof electrical installation, lack of grounding for the circuit.
Holes are drilled in explosion-proof enclosures, button installations cause explosion-proof failure. Long-term exposure to corrosion, high temperatures, and severe vibrations for explosion-proof electrical equipment.
For explosion-proof electrical equipment in use, the AQ 3009-2007 "Electrical Safety and Explosion-Proof Regulations for Hazardous Areas" standard stipulates:
Electrical equipment for explosion-proof use should be inspected by a certified explosion-proof testing center at least once every 3 years to evaluate its performance, installation, maintenance, etc.
Immediate corrective actions must be taken for non-conformities found during inspections, and the inspection report and corrective measures must be filed with the Safety Production Supervision and Administration Department.
Conducting explosion-proof site inspections on electrical equipment in use is not only a requirement of the safety production department, but also a testament to the company's emphasis on its own life and property safety.
