What does the II Class explosion-proof mark consist of? Today, let's break it down so you'll never be scammed again~
Firstly, Class II signifies non-mining gas explosion-proof, which is the fundamental premise. "Ex" denotes explosion-proof, followed by the explosion-proof type, such as Exd (flameproof) and Exe (increased safety), but the specific markings should be consulted. Next are the gas groups and temperature groups, with EPL representing the equipment protection level. These are all key parameters in determining explosion-proof performance.
Not all Class II explosion-proof equipment is the same. For instance, some explosion-proof certificates标注are marked with "IIB+H2" for explosion-proof, but lack a temperature group. This situation requires attention. Additionally, there are other explosion-proof types associated with equipment, such as intrinsic safety barriers with brackets and non-electric explosion-proof devices, all of which fall under the category of Class II explosion-proof.
