ระดับการป้องกันการระเบิดของอุปกรณ์เติมไฮโดรเจน

The required explosion-proof rating for areas with hydrogen should be IIC T1.

Consequently, any products rated IIB on-site fail to comply with these standards. The classification of explosive gas mixtures in the environment falls into IIA, IIB, and IIC categories. The classification is determined by the medium generating the explosive gases. IIC standards exceed those of IIB, offering enhanced safety.
