Full title and description

DIN EN ISO 12945-3:2021-04 — Textiles — Determination of fabric propensity to surface pilling, fuzzing or matting — Part 3: Random tumble pilling method. This document specifies a standard laboratory method using a random‑tumble pilling tester to evaluate resistance to pilling, fuzzing and matting for most woven and knitted fabrics (including napped constructions). The DIN designation is the European adoption of ISO 12945-3:2020 and is published in both English and German.

Abstract

This part of ISO 12945 defines the random tumble pilling test procedure for assessing the propensity of textile fabrics to form pills, to fuzz, or to mat on the surface. It describes specimen preparation, apparatus, test conditions, tumbling procedure and the reporting of results; it is intended for fabrics that can tumble freely but is not applicable to constructions that cannot.

Scope

The standard specifies a method using a random tumble pilling tester to determine the resistance of textile fabrics to surface pilling, fuzzing and matting. It applies to most woven and knitted fabrics including napped constructions (e.g., fleeces). It excludes specimens that cannot tumble freely in the tester drum. The procedure covers specimen preparation, conditioning, tumbling parameters, evaluation and test reporting.

Key topics and requirements

• Random‑tumble pilling tester: apparatus description and required calibration/maintenance.
• Specimen preparation and conditioning under defined atmosphere prior to testing.
• Defined tumbling time/rotation cycles and load conditions for repeatable results.
• Assessment requirements: removal of loose debris, use of defined assessment method (visual grading is handled by ISO 12945‑4); reporting the number of observations and test conditions.
• Limits and applicability: suitable for most woven/knitted and napped fabrics; not for materials that cannot tumble freely.
• Requirements for test report content and normative references.

Typical use and users

Used by textile testing laboratories, quality control teams in textile and apparel manufacturers, material specification engineers, R&D groups developing fabrics or surface finishes, certification bodies and standards committees. Typical applications include acceptance testing, comparative evaluation of fabric constructions or finishes, and supporting product claims about pilling and surface appearance.

FAQ

Q: What is this standard?

A: DIN EN ISO 12945-3:2021-04 is the German/European adoption of ISO 12945-3:2020; it defines the random tumble pilling method for assessing a fabric's propensity to pill, fuzz or mat.

Q: What does it cover?

A: It covers apparatus, specimen preparation, conditioning, tumbling procedure, evaluation and reporting for pilling/fuzzing/matting testing using a random‑tumble pilling tester. It is intended for most woven and knitted fabrics (including napped fabrics) but not for constructions that cannot tumble freely.

Q: Who typically uses it?

A: Textile testing laboratories, QC departments, manufacturers, material developers, certification bodies and standards committees use this method for product development, QC/acceptance testing and comparative evaluations.

Q: Is it current or superseded?

A: The ISO source edition is ISO 12945‑3:2020 (Edition 2, published Oct 2020). The DIN/EN adoption was published in 2021 (DIN EN ISO 12945‑3:2021‑04). The 2020/2021 texts superseded the earlier 2014 edition. Users should check national bodies for any later amendments or revisions.

Q: Is it part of a series?

A: Yes — it is Part 3 of the ISO 12945 series on determination of fabric propensity to pilling, fuzzing and matting; other parts include the pilling box method (Part 1), modified Martindale (Part 2) and the visual assessment method (Part 4).

Q: What are the key keywords?

A: pilling, fuzzing, matting, random tumble, textile test method, ISO 12945-3, fabric appearance, specimen conditioning
