    Significance and Use

    5.1 This test method is considered satisfactory for acceptance testing of commercial shipments because current estimates of between-laboratory precision are acceptable and the method has been used extensively in the trade for acceptance testing.

    5.2 In cases of dispute, the statistical bias, if any, between the laboratory of the purchaser and the laboratory of the seller should be determined, with each comparison being based on testing randomized specimens from one sample of fabric.

    5.3 This test method is used as an indication of the propensity of yarns to shift or distort in a fabric. Such distortions are objectionable due to the resulting changes in appearance. These appearance changes are sometimes referred to as “finger marks” or “shift marks.”

    5.4 It is recommended that fabrics be tested in their original condition and also after laundering or drycleaning, or both, depending upon the intended use of the material.

    1. Scope

    1.1 This test method covers the measurement of yarn distortion of one set of yarns over the other in woven cloth following the application of surface friction. This test method especially is applicable to open-weave fabrics, such as nettings, marquisettes, gauzes, chiffons, and heavier fabrics made from slippery surface yarns.

    Note 1: For the determination of yarn slippage in woven fabrics, refer to Test Method D434.

    1.2 The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are provided for information only.

    1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

    1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
