Requirements for obtaining explosion-proof certificates for chemical storage cabinets
As a combination 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 combined equipment as a whole must be that all electrical components are purchased and installedExplosion proof certificateAnd the explosion-proof level of each electrical component must not be lower than the overall levelExplosion proof levelRequirements. The explosion-proof mark of the overall explosion-proof certificate is a combination of explosion-proof marks for various electrical components.
Due to the large size of such equipment, transportation is inconvenient. Zhongnuo testing is generally a ready-made testing method.
The following is a successful case of Zhongnuo testing, and the explosion-proof mark is: Ex d e ib nC Ⅱ B T4 Gc
