橡胶或塑料涂覆织物.结合剪切挠曲和摩擦抵抗性的测定

[中文适用范围]： 本国际标准规定了两种评估橡胶或塑料涂层织物的抗剪切、弯曲和摩擦联合性能的方法。 摩擦可以通过施加压力脚来强制（方法 A），也可以通过测试件表面之间的简单接触引起（方法 B）。 方法 B（不使用压力脚）在所有情况下都是首选，其中脚会通过研磨作用损坏测试件，但不需要这样做，例如具有粘性表面的材料、粗糙表面上的轻质涂层（例如聚氨酯）。 该测试可以在交付时或经过润湿或加速老化等预处理后的产品上进行。 [外文原描述]： ISO 5981:2007 specifies two methods of evaluating the resistance to combined shear flexing and rubbing of rubber- or plastics-coated fabrics. Rubbing is either forced by application of a pressure foot (method A), or is caused by simple contact between the faces of the test pieces (method B). Method B (without application of the pressure foot) is preferred in all cases where the foot would damage the test piece through an abrasive effect where this is not required, e.g. materials with sticky surfaces, light coatings such as polyurethanes on rough surfaces. The test may be carried out on products as delivered or after pre-treatments such as wetting or accelerated ageing. NOTE The results obtained using method A and method B cannot be compared as there is no correlation between the two methods.
