ESD Vinyl Flooring Testing

The ESD anti-static conductive polyvinyl chloride (PVC) Flooring ground detection instrument should comply with the requirements of “Common Detection Instruments” in this specification.

Test environment: The temperature should be between 15-30 ℃; The relative temperature should be less than 70%.

The surface resistance and system resistance values of anti-static polyvinyl chloride (PVC) flooring should be measured using the following methods:

1. Measurement of surface resistance: The entire anti-static ground should be divided into 2-4m2, and a measurement area of 30% -50% should be randomly selected. The two electrodes should be placed on the surface of the veneer with a spacing of 900mm, and the contact between the electrodes and the veneer should be good. 4-8 values should be measured and recorded within the same 2-4 m2 area.

Measurement of system resistance: Several points should be randomly selected in the area closest to each grounding terminal. One electrode should be in good contact with the surface of the panel, and the other electrode should be connected to the grounding terminal. The system resistance value should be measured and recorded.

The quality assessment method should be carried out in accordance with the provisions of “Sampling Procedures and Tables for Batch Inspection by Attribute”.

The electrical performance indicators should meet the following requirements:

1. Static conductive type is required, with surface resistance and system resistance values lower than 1 × 106Ω。

2. It is required to have electrostatic dissipation type, with surface resistance and system resistance values between 1 × 106-1 × Between 109 Ω.

The grounding resistance value of the 3 system should meet the design requirements.

The appearance performance should meet the following requirements:

1. There should be no hollowing, layering, or cracking;

2. No obvious unevenness;

3. No obvious scratches;

4. No obvious color difference.

The unit undertaking anti-static polyvinyl chloride (PVC) ground testing should be an authoritative institution authorized by the state with corresponding testing report qualifications.
