Overview

SIST EN ISO 20932-1:2020/A1:2022 is an international amendment to the textile standard for determining the elasticity of fabrics specifically through strip tests. Developed collaboratively by ISO Technical Committee ISO/TC 38 and CEN/TC 248, this amendment refines the original ISO 20932-1:2018 standard to enhance precision and uniformity in textile elasticity measurements. It was officially approved in October 2021 and implemented as a European Standard from 2022.

This standard plays a critical role in providing consistent methods for assessing fabric stretch and recovery properties, essential for quality control, product development, and compliance within the textile and apparel industries.

Key Topics

• Textile Elasticity Testing: The standard focuses on evaluating fabric elasticity using strip tests, measuring how textile specimens extend and recover under specified force or extension cycles.

• Measurement Parameters:

  • Elongation (S): Percentage increase in fabric length under maximum force during test cycles.
  • Permanent Deformation (C): The residual deformation after a recovery period, expressed both as a distance and percentage.
  • Recovered Extension (D): The amount of extension regained after deformation.
  • Elastic Recovery (R): The percentage of the original extension recovered, indicating fabric resilience.

• Test Procedures:

  • Extension and retraction rates aligned proportionally to the specimen’s initial length (e.g., 100% length per minute).
  • Precise definition updates to terms such as recovered elongation, permanent deformation, and elastic recovery enhance clarity.

• Standardization Compliance: Mandates adherence by CEN member states ensuring uniform application in EU countries and beyond.

• Technical Collaboration: This amendment reflects synergy between ISO and European standardization bodies, reinforcing international harmonization of textile physical tests.

Applications

The SIST EN ISO 20932-1:2020/A1:2022 standard is vital for:

• Quality Control in Textile Manufacturing: Ensuring fabric elasticity meets product specifications and withstands wear and deformation.

• Product Development: Supporting designers and engineers in selecting materials with desired stretch and recovery traits for apparel, sportswear, upholstery, and technical textiles.

• Compliance and Certification: Facilitating market access by providing recognized test methods confirming fabric performance characteristics.

• Research and Innovation: Assisting laboratories and R&D teams in improving fabric technologies through reliable elasticity measurement.

• Performance Assessment: Evaluating fabrics used in applications requiring specific stretch properties such as compression garments, medical textiles, and protective clothing.

Related Standards

• ISO 20932 Series: EN ISO 20932-1 is part of a broader series on fabric elasticity, with additional parts covering alternative testing methods and conditions.

• ISO/IEC Directives: Defines the editorial and procedural frameworks for preparing and maintaining international standards including amendments.

• CEN-CENELEC Standards: Coherence with European standards ensures compatibility and legal enforceability within the European market.

• Standards on Textile Conditioning and Physical Tests: Standards that govern test atmospheres and overarching physical textile assessments complement EN ISO 20932-1 requirements.
