ISO 5981:2007规定了两种评估橡胶或塑料涂层织物抗剪切弯曲和摩擦性能的方法。摩擦要么通过施加压力脚(方法a)进行,要么通过试样表面之间的简单接触(方法B)进行。
方法B(不使用压脚)适用于所有情况,即压脚会通过不需要的研磨作用损坏试样,例如表面有粘性的材料、粗糙表面上的聚氨酯等轻涂层。
该试验可在交付的产品上进行,或在湿润或加速老化等预处理后进行。
注:无法比较使用方法A和方法B获得的结果,因为这两种方法之间没有相关性。
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.
