Meaning of applicable scope groups
Division of hazardous areas for explosive gas environments
Different countries and regions divide explosive hazardous areas according to their own standards. Our country divides explosive gas environments into zones, zones and zones based on the frequency and duration of the occurrence of explosive gas mixtures. (Consistent with the International Electrotechnical Commission)
An environment where explosive gas mixtures appear continuously or for a long time.
Area where explosive gas mixture may occur during normal operation.
The area is an environment where explosive gas mixtures are unlikely to occur during normal operation or where explosive gas mixtures will only exist for a short period of time even if they occur.
Zones generally only exist in internal gas spaces such as sealed containers and storage tanks. Zones rarely exist in the actual design process and most cases belong to zones.
Explosive electrical equipment is divided into two categories
Category I electrical equipment for underground coal mines
Category II electrical equipment used in places other than mines
Category electrical equipment is suitable for explosive The maximum test safety gap or minimum ignition current ratio of gas mixtures is divided into three categories: II, II and II and is divided into six groups according to their maximum surface temperature.
Explosive gas mixtures are grouped according to ignition temperature, see table.
Explosive gas mixtures are classified according to their maximum test safety gap or minimum ignition current ratio, see table.

Properties Under specified test conditions, the ratio of the minimum ignition current of explosive mixtures of gas and steam to the minimum ignition current of explosive mixtures of methane. China stipulates that gas and vapor hazardous substances are divided into II [forbidden words], Level II and Level II based on the minimum ignition current ratio. The minimum ignition current ratio is Level II [forbidden word], and the minimum ignition current ratio is Level II. For example, ethane, ethylene, and acetylene are Class II [banned words], Class II, and Class II hazardous substances respectively.
