Explosion proof electrical equipment has obtained a gas explosion-proof certificate. Can it be directly used in environments with combustible dust?

Is the gas explosion-proof level higher or the dust explosion-proof level higher? What's the difference between the two?

Do non electrical equipment such as reducers and brakes used in explosive environments require explosion-proof certification?

Can gas explosion-proof motors be transformed into dust explosion-proof motors?

......

For explosion prevention, I believe everyone will encounter these problems.

In fact, there are different classification methods for domestic explosion-proof certification according to the applicable environment, electrical equipment characteristics, protection types, etc. of the product. For example, it can be divided into electrical explosion-proof certification and non electrical explosion-proof certification, as well as gas explosion-proof certification and dust explosion-proof certification.

Classification of explosion-proof standards

Electrical equipment for explosive gas environments

Electrical equipment for combustible dust environments

With the continuous expansion of the international market, domestic explosion-proof products are also constantly stepping out of the international market. The demand for ATEX certification in the EU market and IECEx certification in the international market is also increasing, and the applicable standards are also different from those in China.
