GB/T 3836.27-2019Explosive atmospheres -- Part 27: Electrostatic hazards -- Test (English PDF)

1 Scope

This section of the Explosive Environment specifies tests to avoid the danger of electrostatic ignition and electric shock caused by equipment, products and processes method.

This section applies to the assessment of electrostatic hazards, or used to develop electrical or non-electrical equipment standards or special product standards.

The standard test methods provided in this section are used to control static electricity, such as surface resistance, leakage resistance to ground, powder resistivity, liquid conductivity,

Capacitance, and evaluation of the ignitability of the triggered discharge. This section is used together with GB/T 3836 series standards.

Note. This section does not replace specific product standards and industrial application standards.

The latest technologies available in this section may deviate slightly from the requirements of other standards, especially in terms of testing climatic conditions. When this

When some of the requirements conflict with the requirements of GB 3836.1, in order to avoid that the previously certified equipment may need to be retested, the GB 3836.1

The requirements apply only to equipment specified in GB 3836.1. For other cases, the requirements of this section apply.
