1. Laboratory Standard Testing (Based on National/Industry Standards)

This type of testing requires professional equipment, and the results are accurate and authoritative. Common standards include GB 12014-2019 "Anti-static Clothing" and GB/T 23316-2009 "Textiles - Evaluation of electrostatic properties - Part 2: Surface charge density", etc.

Surface Resistivity Test

Core Indicator: The surface resistivity of anti-static fabrics is generally required to be between 

10 6 Ω∼10 11 Ω

.Test Method: Use a high-resistance meter. Take a 20cm×20cm fabric sample, place electrodes of specified dimensions (such as parallel electrodes or ring electrodes) on the surface of the sample, apply a DC voltage, and measure the resistance value between the electrodes.

Environmental Requirements: Temperature 

20±2 ∘ C, relative humidity 30±5% (a dry environment can better reflect the anti-static performance).
