Regular inspections are a powerful guarantee for the use and explosion-proof safety performance of explosion-proof equipment used in explosive hazardous areas throughout its life cycle, including production, installation, use, inspection, maintenance, and withdrawal from the market. Relevant laws and regulations in our country have also made corresponding provisions on this matter. In the standard AQ3009-2007 "Electrical Safety and Explosion Protection Code for Hazardous Areas", it is clearly stipulated that regular inspections should be entrusted to safety production testing and inspection institutions with explosion-proof professional qualifications, with a time interval generally not exceeding 3 years. Enterprises should take timely corrective measures based on the inspection results, and file the inspection report and rectification situation with the safety production supervision and management department. In the preface of AQ3009-2007 "Electrical Safety and Explosion Protection Code for Hazardous Areas", it is also explicitly stated that Chapter 4, Chapter 5, Chapter 6, and Chapter 7 are mandatory and must be strictly enforced. So, similar safety regulations are also part of laws and regulations, and mandatory ones must be strictly enforced!
Therefore, as the user of explosion-proof equipment, regular explosion-proof testing of the equipment is not only necessary but also mandatory.
The standards based on which the "Electrical Explosion Prevention Inspection Report for Hazardous Areas" issued by the regular inspection of explosion-proof electrical equipment include but are not limited to:
GB50058-2014 "Design Code for Electrical Equipment in Explosive Hazardous Environments"
GB50257-2014 "Code for Construction and Acceptance of Electrical Equipment in Explosive and Fire Hazardous Environments in Electrical Equipment Installation Engineering"
GB/T3836.15-2017 Electrical Equipment for Explosive Gas Environments Part 15: Electrical Installation in Hazardous Areas (Except for Coal Mines)
AQ3009-2007 Safety Code for Electrical Explosion Protection in Hazardous Areas
