GB/T 12476.9-2010
AbolishedElectrical apparatus for use in the presence of combustible dust - Part 9: Test methods - Method for determining the electrical resistivity of dust in layers
可燃性粉尘环境用电气设备 第9部分：试验方法 粉尘层电阻率的测定方法
Application Summary AI generated
This standard specifies the test method for determining the electrical resistivity of a layer of combustible dust. It is applied in the design, testing, and certification of electrical apparatus intended for use in hazardous areas where combustible dust layers may form, such as in grain processing, chemical plants, and mining facilities. The resistivity measurement helps assess the risk of electrostatic discharge ignition from dust accumulations on equipment surfaces.
