scope:

This standard specifies a method of evaluating the resistance to combined shear flexing and rubbing of rubber or plastics coated fabrics. Rubbing occurs either as a result of contact between the faces of the test pieces or is reinforced by application of a pressure foot. 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 o products as delivered or after pre-treatment such as wetting or accelerated ageing.
