GB/T 12703.5-2020Textiles. Test methods for electrostatic propensity - Part 5: Test method using rotary mechanical friction (English PDF)

1 Scope

This document specifies the method for determining the frictional charging voltage of fabrics using the rotating mechanical friction method:

This document applies to fabrics of various compositions and structures that can withstand frictional charging operations:

This document is not applicable to the evaluation of clothing and clothing materials related to personal safety and protection of electrostatic discharge sensitive devices:

Note: Some fabrics, such as low-strength or loose structure fabrics, may not be able to withstand the mechanical friction in this test method, or may produce erroneous results, in this case

In this case, the method specified in GB/T 12703:1 can be used for testing:

3 Terms and definitions

The following terms and definitions apply to this document:

3:1

Antistatic

The material has the ability to reduce the tendency to obtain electrostatic charge or to make the electrostatic charge quickly dissipate:

3:2

Friction-chargedelectrostaticpotential

The voltage generated by friction between one material and another or the same material:

3:3

Conductive

It has sufficiently high conductivity that the potential difference of any part of the material or object is not enough to have a practical effect:

Note: In general, the resistance of conductive materials is lower than 105ohm, but different standards may have different definitions of the resistance range of conductive materials: […]
