General Information
Relations
Overview
EN ISO 20932-3:2020/A1:2025 is a CEN-endorsed amendment to ISO 20932-3 (Part 3: Narrow fabrics) that updates definitions, test procedures and calculation methods for determining the elasticity of narrow textile fabrics. Approved by CEN in 2025 and intended for national adoption across CEN members, this amendment clarifies key terms and adds precise calculation procedures for reporting elongation, force decay, permanent deformation and elastic recovery.
Key topics and technical requirements
- Scope: Test methods for measuring elasticity and recovery behaviour of narrow fabrics (for example webbings, braids, elastic tapes and narrow trim).
- Updated definitions: Revised definition of recovered extension/recovered elongation (expressed as a percentage and complement to permanent deformation).
- Test speed requirement: The extension/retraction rate is specified at 300% of the initial length per minute (e.g., 100 mm initial length → 300 mm/min).
- Measurement and calculation procedures: Amendment supplies explicit formulae and calculation steps for:
- Elongation (S) at maximum force on the fifth cycle (or at specified cycle),
- Force decay due to time (A) and due to exercising (B),
- Permanent deformation (C) (distance and percentage),
- Recovered extension/elongation (D) (distance and percentage),
- Elastic recovery (R) (distance and percentage).
- Reporting: Test reports must indicate the method used (A or B) - now clarified to read A (including agreed number of cycles) or B - plus all measurement conditions (initial length/pretension, cycle count, holding periods).
- Pretension option: Procedures account for tests performed with or without pretension, defining how clamp distance and reference marks are used in calculations.
Applications and users
This amendment is directly relevant for:
- Textile manufacturers and converters producing narrow elastic components (webbing, straps, elastics, ribbons).
- Quality control and independent testing laboratories that certify mechanical/elastic performance.
- Product designers and R&D teams assessing elastic recovery, durability and deformation under repeated loading.
- Procurement, compliance and standards officers specifying performance requirements in product specifications and supplier contracts.
Practical uses include ensuring consistent elasticity metrics for garment components, safety straps, medical elastic bands and technical narrow fabrics used in automotive, medical and consumer products.
Related standards and context
- Part of the ISO 20932 series on determination of fabric elasticity; this amendment aligns ISO 20932-3:2018 with ISO/EN requirements.
- Issued under the Vienna Agreement collaboration between ISO/TC 38 (Textiles) and CEN/TC 248.
- CEN adoption: EN ISO 20932-3:2020/A1:2025 - national standards bodies are required to implement or endorse this amendment.
Keywords: EN ISO 20932-3:2020/A1:2025, textiles elasticity test, narrow fabrics elasticity, elastic recovery, permanent deformation, force decay, textile testing standard.
