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:
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:
The grounding resistance value of the 3 system should meet the design requirements.
The appearance performance should meet the following requirements:
The unit undertaking anti-static polyvinyl chloride (PVC) ground testing should be an authoritative institution authorized by the state with corresponding testing report qualifications.
