Standard Test Method for
Pilling Resistance and Other Related Surface Changes of
Textile Fabrics: Brush Pilling Tester1

This standard is issued under the fixed designation D 3511; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. 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.
