Standard Test Method for Pilling Resistance and Other Related Surface Changes of Textile Fabrics: Brush Pilling Tester

SCOPE
1.1 This test method covers the determination of the propensity of a fabric to form pills from fuzz under test conditions intended to simulate normal wear using the brush pilling tester. This procedure is generally applicable to all types of apparel fabrics including both woven and knitted fabrics.
Note 1—For other test methods for the pilling resistance of textiles, refer to Test Methods D 3512, D 3514, and D 4970.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as the standard. Within the text, the inch-pound units are to be regarded separately as the standard. Within the text, the inch-pound units are shown in parentheses. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
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 and health practices and determine the applicability of regulatory limitations prior to use.
