9、he fabric.The degree to which the forcecauses yarns to shift distorting the original symmetry of theweave is taken as a measure of ease of yarn distortion in thefabric.The degree of distortion is reported in terms of thewidest opening,measured in hundredths of an inch.5.Significance and Use5.1 This
10、test method is considered satisfactory for accep-tance testing of commercial shipments because current esti-mates of between-laboratory precision are acceptable and themethod has been used extensively in the trade for acceptancetesting.5.2 In cases of dispute,the statistical bias,if any,betweenthe l
11、aboratory of the purchaser and the laboratory of the sellershould be determined,with each comparison being based ontesting randomized specimens from one sample of fabric.5.3 This test method is used as an indication of the propen-sity of yarns to shift or distort in a fabric.Such distortions areobje
12、ctionable due to the resulting changes in appearance.These appearance changes are sometimes referred to as“fingermarks”or“shift marks.”1This test method is under the jurisdiction ofASTM Committee D13 on Textilesand is the direct responsibility of Subcommittee D13.59 on Fabric Test Methods,General.Cu
