Scope of application group meaning
Division of hazardous areas of explosive gas environment
Different Countries and regions classify explosion hazard areas according to their respective standards. Our country divides explosive gas environments into zones and zones based on the frequency and duration of the occurrence of explosive gas mixtures. In accordance with the International Electrotechnical Commission
Area 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 in which 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.
Explosion-proof 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 II electrical equipment, according to its applicable The maximum test safety gap or minimum ignition current ratio of explosive gas mixtures is divided into three categories: II, IIB 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 R, see table.

Properties: Under the specified test conditions, the ratio of the minimum ignition current of the gas vapor explosive mixture to the minimum ignition current of the methane explosive mixture . China stipulates that gas and vapor hazardous substances are classified into Class II [forbidden words], Class IIB and Class II based on the minimum ignition current ratio. The minimum ignition current ratio is Class II, and Class IIB is Class II. For example, ethane, vinyl, and acetylene are classified as Class II [banned words], Class IIB, and Class II hazardous substances respectively.
