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 entire lifecycle, including production, installation, use, inspection, maintenance, and exit from the market. Relevant laws and regulations in our country have also made corresponding provisions for this. In the standard AQ3009-2007 "Code for Electrical Safety and Explosion Protection in Hazardous Areas", it is clearly stipulated that regular inspections should be entrusted to safety production testing and inspection institutions with explosion-proof professional qualifications, and the time interval should generally not exceed 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 "Code for Electrical Safety and Explosion Protection in Hazardous Areas", it is also clearly stated that Chapters 4, 5, 6, and 7 are mandatory and must be strictly implemented. 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 a mandatory requirement.
