2024年3月22日 · ATEX 防爆产品的分区（Zone）是根据可能存在爆炸性气体的环境来划分的，以确定相应的防爆要求和设备选型。以下是 Zone 0、Zone 1 和 Zone 2 的区分标准：

2018年10月19日 · 1.区域爆炸性物质分类，主要区分环境内之爆炸性物质. 分类一(Class I)---可燃性气体、蒸发气化或液态物质. 分类二(Class II)---可燃性粉尘. 分类三(Class III)--可燃性纤维或飞扬物. 2.危险区域等级分类，主要依据爆炸性环境内危险物质存在之频率和期间分成以下两类：

2022年5月31日 · Zone 1 is an area in which an explosive atmosphere is likely to occur occasionally in normal operation. It may exist because of repair, maintenance operations, or leakage. Zone 2 is a place in which an explosive atmosphere is not likely to occur in normal operation but, if it does occur, will persist for a short period only.

A Zone 1 hazardous area is classified as a place in which an explosive atmosphere consisting of a mixture with air or flammable substances in the form of gas, vapour or mist is likely to occur in normal operation occasionally.

Zone 1 is an area that is classified ‘as a place in which an explosive atmosphere consisting of a mixture with air or flammable substances in the form of gas, vapours and mists is likely to occur occasionally during normal operation’, whereas Zone 2 is an area that is classified ‘as a place in which an explosive atmosphere consisting of a ...

Zone 1: area in which an explosive gas atmosphere is likely to occur occasionally in normal operation. (between 0,1 and 10% of the time). Zone 2: area in which an explosive gas atmosphere is not likely to occur in normal operation, but, if it does occur, will exist for a short period only (less than 0,1% of the time)

Zone 1 refers to an area where an explosive atmosphere is likely to occur during normal operations, albeit for shorter periods compared to Zone 0. It represents a lower but still significant level of risk, requiring appropriate safety precautions and specialized equipment.

Zones compares to classes and divisions in the Class/Division system. Group define the type of hazardous material and (partly) the location of the surrounding atmosphere. Group is divided in three groups where Group I is reserved for mining locations.

Zone 1 and Zone 2 are terms commonly used to describe different areas or regions, particularly in the context of hazardous or potentially explosive environments. These zones are relevant to industries such as oil and gas, chemical processing, and pharmaceuticals, where the presence of flammable gases, vapors, or dust is a significant safety ...

In North America-Division, Class, and Group Categories: Division I – There is a high probability of an explosive atmosphere in normal operation. This can be for part of the time, up to all the time. Division II – There is a low probability of an explosive atmosphere being present during normal operation. The North American class designations are:
