    1. Scope

    1.1 This test method covers the determination of the resistance to the formation of pills and other related surface changes on textile fabrics using the Martindale tester. The procedure generally is applicable to all types of fabrics, being particularly suitable for woven fabrics.

    Note 1—For other methods, if testing the pilling resistance of textiles, refer to Test Methods D 3511, D 3512, and D 3514.

    1.2 This test method is not suitable for fabrics thicker than 3 mm (0.125 in.) because such fabrics cannot be mounted in the specimen holder.

    1.3 The fabric may be laundered or dry cleaned before testing.

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

    1.5 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 and health practices and determine the applicability of regulatory limitations prior to use.
