Explosion-proof system certification
Thread Content
I am working in an environment with explosive gases (with ethylene as the representative gas) and use explosion-proof equipment, which includes intrinsically safe explosion-proof modules, flameproof explosion-proof modules, and encapsulated explosion-proof modules. These three types of modules are separate products. My question is: 1. If the flameproof enclosure of the flameproof explosion-proof module is a product that already has an explosion-proof certification, does the explosion-proof module still need to apply for such certification? 2. Is it necessary to apply for explosion-proof certification for the entire system? I would be extremely grateful if that master could offer some guidance~~
Modules are not necessary; you just need to place all the modules inside the explosion-proof enclosure and obtain certification as a whole.
This refers to explosion protection for the entire device; the whole unit needs to undergo new explosion protection certification, and the certification mark and level are determined based on the levels of these three modules.
