42、ncipleA circular specimen, mounted in a specimen holder and subjected to a defined load, is rubbed against an abrasive medium (standard fabric) in a translational movement tracing a Lissajous figure, the specimen holder being additionally freely rotatable around its own axis perpendicular to the pla

43、ne of the specimen. The evaluation of the abrasion resistance of the textile fabric is determined from the inspection interval to breakdown of the specimens.The specimens are mounted in specimen holders with foam backing. Specimens with a mass per unit area 500 g/m2are mounted in specimen holders wi

44、thout foam. Pile fabrics which are tested without foam backing are subjected to a specified preparatory treatment (see 7.5.2).Two abrasion load parameters are specified. The total effective mass of the abrasion load (i.e. the mass of the specimen holder assembly and the appropriate loading piece) ar

46、sting is continued up to breakdown (see Clause 8) of the test specimen.The inspection interval is determined by the specimen breakdown. The number of rubs is recorded at which specimen breakdown is not yet observed (this number of rubs is the upper limit of the time elapsed before specimen breakdown

47、 and, at the same time, the lower limit of the abrasion interval at which specimen breakdown occurs).5 Apparatus and materials5.1 Test apparatus and auxiliary materials, as specified in ISO 12947-1.5.2 Template.A mask made of a rigid transparent material with a hole of diameter (2,5 0,1) mm through
