Main purpose
It is applicable to the determination of antistatic properties of Antistatic Fabrics.
Test principle
The standard cloth is wound on the friction rod and rubs with the sample to electrify the sample. After the friction rod rubs the sample three times at the friction speed of 2S each time, the friction rod lifts away from the sample, and the potential value and peak potential value when the sample decays for 0.5s are detected by the detection device, so as to evaluate the anti-static performance of the sample.
Applicable standards
