The gas explosion-proof certification and dust explosion-proof certification that we often refer to are divided based on the applicable locationss of the equipment.
Explosion proof equipment used in various hazardous gas environments shall be certified for gas explosion prevention, and equipment used in various combustible dust areas shall be certified for dust explosion prevention.
In explosion-proof certification, gases are divided into IIA, IIB, and IIC, and dust is divided into IIIA, IIIB, and IIIC. Their characteristics and environments are different, and the explosion-proof protection measures taken for equipment are also different. The two cannot be mixed. Of course, some products can be used in both gas and dust environments by considering the requirements of gas and dust explosion-proof standards when applying for explosion-proof certification. On the explosion-proof certificate, it can also be seen through the explosion-proof mark whether it belongs to gas explosion-proof certification or dust explosion-proof certification.
