In explosive environments, in addition to the use of electrical equipment, a large amount of non electrical equipment is also used, such as mechanical valves, chain hoists, exoskeleton hydraulic/pneumatic equipment, etc. Although these devices do not use electricity and have no power themselves, they have high-speed moving parts during operation, and may produce sparks due to collisions during use. The high temperature generated by friction, compression, and work is particularly important for explosive hazardous areas, These are all dangerous ignition sources with the risk of igniting explosive substances in the environment, so their explosion-proof performance needs to be considered as well.


Executive standards for explosion-proof certification of non electrical equipment:

GBT 3836.28-2021 Explosive Atmospheres Part 28: Basic Methods and Requirements for Non Electrical Equipment Used in Explosive Atmospheres

GBT 3836.29-2021 Explosive Atmospheres Part 29: Non electrical equipment structures for explosive environments Safety type "c", controlled ignition source type "b", liquid immersion type "k"


Zhongnuo Testing has also had a large number of successful evidence collection cases in non electrical equipment, including chain hoists, handcart carts, mechanical seals, etc. If you have any needs in this regard, you can contact us for further detailed communication!
