What test items are required for the explosion-proof certification of the product? What specific requirements are there for the product's explosion-proof design? How can the design be carried out to pass the explosion-proof test requirements? These are questions many customers of explosion-proof product manufacturers want to know. Here, ZhongNuo Testing addresses these concerns.

Currently, domestic explosion-proof certification follows the GB/T 3836 series standards. There are general and specific standards for explosion-proof products. Different product structures, electrical parameters, installation methods, and usage locations require various certification standards and testing items. Therefore, the explosion-proof design and requirements for products also vary. For example, for intrinsically safe products, typical test items include appearance and structure inspection, spark ignition test, dielectric strength, battery and battery pack testing, temperature rise test, transient energy test, etc. For flameproof products, the main test items include heat and cold resistance tests, internal ignition non-propagation, shell pressure resistance, IP testing, temperature rise test, etc.
