Explosion proof electrical facilities and equipment must be installed and used in hazardous areas containing flammable and explosive gases and dust, such as coal, petroleum, and chemical industries. Many end users believe that as long as explosion-proof electrical equipment is installed in explosive hazardous areas, everything will be fine. In many cases, the so-called explosion-proof electrical appliances do not have explosion-proof certificates or their explosion-proof certificates are expired or forged. The nameplate is inconsistent with the explosion-proof certificate, the explosion-proof type selection is not in line, gas explosion-proof electrical equipment and dust explosion-proof electrical equipment are mixed, the wiring of explosion-proof electrical appliances is improper, the circuit is not grounded, drilling holes and installing buttons on the explosion-proof shell cause explosion-proof failure, and explosion-proof electrical appliances are exposed to corrosion, high temperature, intense vibration, etc. for a long time, which affects safety production and brings great safety hazards.

Regarding explosion-proof electrical appliances in use, the AQ 3009-2007 "Code for Electrical Safety and Explosion Protection in Hazardous Areas" standard stipulates that explosion-proof electrical appliances in use must be tested for their performance, installation, maintenance, etc. by a qualified explosion-proof testing agency at least once every three years. Any non compliant items must be promptly rectified, and the inspection report and rectification situation must be filed with the safety production supervision and management department.

Conducting explosion-proof on-site inspections on explosion-proof electrical equipment in use is not only a requirement of the safety production department, but also a concern of the enterprise for its own life and property safety.

Explosion proof equipment testing service field:
Including industries or fields such as petroleum, chemical, coal, military, aerospace, ships, ports, marine engineering, gas engineering, pharmaceuticals, machinery, textiles, electricity, light industry, grain processing and storage, wood processing, etc., hazardous areas with explosive gas environments and explosive or combustible dust environments are ensured to ensure explosion-proof safety and safeguard the development of our country and national economy.

Business scope of explosion-proof electrical safety testing:
1. Explosion proof safety inspection of explosion-proof electrical equipment in hazardous areas
2. Explosion proof testing of explosive dust
3. On site assessment and verification of electrical equipment in dust explosion sites
4. Quality inspection and safety acceptance inspection of explosion-proof engineering in hazardous and explosive areas;
5. Explosion proof electrical and non electrical equipment, as well as explosion-proof engineering consulting/design/review/modification/construction/supervision/acc
