AbolishedElectrical apparatus for use in the presence of combustible dust—Part 3: Classification of areas where combustible dusts are or may be present
可燃性粉尘环境用电气设备 第3部分：存在或可能存在可燃性粉尘的场所分类
Application Summary AI generated
This standard provides the methodology for classifying locations where combustible dusts are present or may be present, based on the frequency and duration of explosive dust atmospheres. It is applied by engineers and safety professionals in industries such as grain handling, chemical processing, and mining to designate zones (e.g., Zone 20, 21, 22) for selecting appropriate electrical equipment. The classification directly informs the design, installation, and maintenance of electrical apparatus to prevent ignition in hazardous dust environments.
