GB/T 3923.1-2013 in English

《GB/T 3923.1-2013纺织品 织物拉伸性能 第1部分：断裂强力和断裂伸长率的测定（条样法）》由TC209（全国纺织品标准化技术委员会）归口，TC209SC1（全国纺织品标准化技术委员会基础标准分会）执行，主管部门为中国纺织工业联合会。
GB/T3923的本部分规定了采用条样法测定织物断裂强力和断裂伸长率的试验方法。
本部分主要适用于机织物,也适用于其他技术生产的织物,通常不用于弹性织物、土工布、玻璃纤维织物以及碳纤维和聚烯烃扁丝织物。
本部分包括在试验用标准大气中平衡和湿润两种状态的试验。
本部分规定使用等速伸长(CRE)试验仪。

1 Scope

This Part of GB/T 3923 specifies a procedure to determine the maximum force and elongation at maximum force of textile fabrics using a strip method.
The method is mainly applicable to woven textile fabrics. It can be applicable to fabrics producedby other techniques. It is not normally applicable to woven elastic fabrics, geotextiles, nonwovens, coated fabrics, textile-glass woven fabrics and fabrics made from carbon fibres or polyolefin tape yarns.
The method specifies the determination of test specimens in equilibrium with the standard atmosphere for testing, and of test specimens in the wet state.
The method is restricted to the use of constant rate of extension (CRE) testing machines.

3 Terms and Definitions

For the purposes of this document, the following terms and definitions apply.
3.1
Constant-rate-of-extension (CRE) testing machine
Tensile-testing machine provided with one clamp which is stationary and another clamp which moves with a constant speed throughout the test, the entire testing system being virtually free from deflection.
