Test method of anti-static chair

Anti-static chair has the characteristics of comfortable texture, breathable heat dissipation, impact resistance, corrosion resistance, wear resistance and fission resistance. It is widely used in laboratories, electronic production workshops and dust-free workshops. It is an indispensable tool for working in static sensitive areas , Today I will introduce the test method of anti-static chair.

The anti-static chair is mainly composed of three parts, namely the backrest, the ESD cushion and the metal accessories. It not only has a very good electrostatic discharge performance, but also can effectively discharge static electricity to the ground. In order to ensure that the dust-free studio meets the standard requirements, strict dust generation and ion pollution tests must be carried out on the anti-static chair materials. The test standards for anti-static chairs are conducted with reference to the anti-static test specifications for the application of electronic products and manufacturing systems. The test methods are as follows:
1. The test position between the backrest and the chair surface must be correct, and the point-to-point resistance test method must meet the corresponding specifications. To
2. The system resistance test between the caster and the chair surface should also meet the corresponding requirements. When testing the anti-static chair, a conductive plate of a certain size should be placed under the caster, and the contact should be good; An electrode makes contact with the conductive plate.
3. Point-to-point resistance and system resistance test. The electrode material used must be copper or stainless steel, the electrode structure used must meet the size requirements, and the hardness, thickness and volume of the electrode contact end materials must meet the requirements.

When testing the point-to-point resistance of the anti-static chair, the material should be placed on the actual use state or on an insulated table. The volume resistance and surface resistance of the mesa must meet the requirements, and the distance between the electrodes must also meet the requirements.

The test method of the anti-static chair is introduced here. If the anti-static chair meets the requirements of the standard after the test, it can be used. If after the test, it does not meet the relevant regulations In the event of an accident, the product that does not meet the requirements must be remade.
