ISO 13935-2:2014规定了垂直于接缝施加力时,测定缝接缝最大力的方法。ISO 13935-2:2014描述了称为抓取试验的方法。
该方法主要适用于机织纺织物,包括表现出弹性纤维、机械或化学处理赋予的拉伸特性的织物。它可能适用于其他工艺生产的织物。它通常不适用于土工布、非织造布、涂层织物、玻璃纤维织物以及由碳纤维或聚烯烃带纱制成的织物。
缝制的织物可以从之前缝制的物品中获得,也可以根据对结果感兴趣的各方的约定从织物样品中制备。
该方法仅适用于直线焊缝,不适用于曲线焊缝。
该方法仅限于使用恒定延伸率(CRE)试验机。
ISO 13935-2:2014 specifies methods for the determination of seam maximum force of sewn seams when the force is applied perpendicularly to the seam. ISO 13935-2:2014 describes the method known as the grab test.
The method is mainly applicable to woven textile fabrics, including fabrics which exhibit stretch characteristics imparted by the presence of an elastomeric fibre, mechanical or chemical treatment. It may be applicable to fabrics produced by other techniques. It is not normally applicable to geotextiles, nonwovens, coated fabrics, textile-glass woven fabrics and fabrics made from carbon fibres or polyolefin tape yarns.
The sewn fabrics may be obtained from previously sewn articles or may be prepared from fabric samples, as agreed by the parties interested in the results.
This method is applicable to straight seams only and not to curved seams.
The method is restricted to the use of constant rate of extension (CRE) testing machines.
