ASTM D 3511/D3511M : 2016 : REDLINE

1.1This test method covers the determination of the propensity of a fabric to form pills and other related surface changes on textiles using the brush pilling tester. This procedure is generally intended to be used for upholstery, automotive, luggage and heavy duty uniform fabrics because it is highly abrasive. This does not, however, preclude it from being used for other types of fabrics. If unsure, comparison testing should be performed to ensure that this test method replicates pilling on the final product.

1.2The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.3This 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.
