What test items are required for product explosion-proof certification? What specific requirements are there for the product's explosion-proof design? How can one design to pass the explosion-proof test requirements smoothly? This is information many customers producing explosion-proof products are eager to know. Here, Zhongnuo Inspection answers your questions.

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 different certification standards and testing items. Therefore, the explosion-proof design and requirements for products 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 explosion-proof products, the main test items include heat and cold resistance tests, internal ignition non-propagation, shell pressure resistance, IP testing, temperature rise test, etc.
