https://www.chinesestandard.net, 18. apr. 2016 - 15 sider
This Part of GB/T 3923 specifies a procedure for the determination of maximum force of textile fabrics known as the grab test. The method is mainly applicable to woven textile fabrics. It may be applicable to fabrics produced by other techniques. It is normally not applicable to woven elastic fabrics, geotextiles, nonwovens, coated fabrics, textile-glass woven fabrics and fabrics made from carbon fibres or polyolefin tape yarn.
