Explosion-proof certification refers to a technical authentication process that verifies whether equipment complies with explosion-proof standard requirements. It involves conducting type tests and routine tests, and issuing qualification certificates to products that pass the inspections. It is mainly applicable to Ex equipment or components used in explosive atmospheres, aiming to ensure their safety and applicability.

Since explosion-proof products are deployed in places with flammable and explosive hazards, to prevent the equipment itself from igniting the surrounding explosive substances due to its own factors, the equipment must be designed to avoid becoming an ignition source.

The national explosion-proof standard GB/T 3836 also stipulates that equipment used in hazardous locations must undergo testing and certification by relevant national institutions. In addition, the standard AQ 3009-2007 for places with flammable and explosive hazards requires regular inspections, mandating that only equipment and products with explosion-proof certification be installed and used in such locations. The requirements of explosion-proof standards must also be followed during daily maintenance and servicing.

To apply for an explosion-proof certificate for products, the following documents are generally required: electrical schematic diagrams, general assembly drawings, structural drawings, nameplate drawings, Bill of Materials (BOM), technical descriptions, enterprise standards, etc. For explosion-proof equipment with plastic housing materials, equipped with wireless functions, laser emission devices, batteries, etc., corresponding technical documents or test reports must also be provided.
