Overview
EN ISO 12945-3:2020 - “Textiles - Determination of fabric propensity to surface pilling, fuzzing or matting - Part 3: Random tumble pilling method” (CEN adoption of ISO 12945-3:2020) defines a laboratory method to evaluate a fabric’s resistance to pilling, fuzzing, and matting using a random-tumble pilling tester. The method applies to most woven and knitted fabrics, including napped textiles (e.g., fleeces, inlay fabrics), but excludes fabrics that cannot tumble freely.
Key topics and technical requirements
- Test principle: Specimens are tumbled under defined conditions in a lined cylindrical test chamber to simulate abrasive wear; surface changes are assessed visually after specified tumbling intervals.
- Apparatus: Use of a random tumble pilling tester with lined chambers (polychloroprene liners) and maintenance/verification procedures for apparatus performance. Annex A provides apparatus checking and liner preparation guidance.
- Specimen preparation: Requirements for sampling, specimen edge fixation, number of specimens, marking and pre-treatment of laboratory samples.
- Conditioning and atmosphere: Tests are conducted in controlled atmosphere per ISO 139 (standard conditioning for textiles).
- Assessment: Visual evaluation of pilling, fuzzing and matting is performed following the assessment principles (see ISO 12945-4 for visual analysis procedures referenced in Clause 10).
- Terminology and scope limits: Clear definitions for pill, pilling, fuzzing, matting and jamming (entanglement) are provided to ensure consistent interpretation.
- Documentation: Test report content and result reporting requirements are specified to support reproducibility and traceability.
- Annexes: Annex C gives rationale (notably for napped fabrics) and Annex B outlines an alternative procedure.
Applications
- Quality control of garments, home textiles and technical textiles to measure fabric propensity to pilling, fuzzing, and matting.
- Comparative performance testing during product development, material selection and supplier evaluation.
- Supporting specifications for retail product acceptance, performance claims and warranty assessments.
- Research and R&D labs studying fibre, yarn and fabric interactions that influence surface wear.
Who should use this standard
- Textile manufacturers and mills performing in-house QC
- Independent testing laboratories and certification bodies
- R&D teams and textile engineers developing pill-resistant fabrics
- Retailers and brand quality assurance for product specification and compliance
