This International Standard 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, 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 using method A and method B should not be compared as there is no correlation between the two methods.
