Requirements for obtaining explosion-proof certificate for chemical storage cabinets
As a combined explosion-proof equipment, chemical storage cabinets are generally composed of explosion-proof distribution devices, explosion-proof lights, explosion-proof buttons, smoke detectors, sound and light alarms, air conditioners, flexible connecting pipes, etc. The basic requirement for obtaining an explosion-proof certificate for modular equipment as a whole is that all electrical components must be purchased and installedExplosion proof certificateAnd the explosion-proof level requirements for each electrical component must not be lower than the overall levelExplosion proof graderequirement. The explosion-proof mark of the overall explosion-proof certificate is a combination of the explosion-proof marks of various electrical components.
Given that these devices are relatively large and inconvenient to transport. Zhongnuo testing is generally a ready-made testing method.
The following is a case of successful certification by Zhongnuo Testing. The explosion-proof mark is: Ex d e ib nC Ⅱ B T4 Gc
