Overview
EN ISO 13937-3:2000 - Textiles - Tear properties of fabrics - Part 3: Determination of tear force of wing-shaped test specimens (Single tear method) - is a CEN-adopted ISO standard that defines the wing test (single tear method) for measuring the force required to propagate an already-started tear in a fabric. The procedure uses a specially cut, wing-shaped test specimen clamped so the wings are inclined at a defined angle to the thread direction. This Part is principally intended for woven textile fabrics and provides a repeatable way to quantify tear propagation resistance.
Key Topics
- Scope and applicability: Specifies the single tear (wing) method for assessing tear propagation in fabrics, primarily woven materials.
- Specimen geometry: Describes the use of a wing-shaped specimen cut to form two wings for clamping at a defined angle relative to thread direction.
- Measured value: The tear force recorded is the force required to continue propagation of a pre-initiated tear.
- Test intent: Designed to give consistent, comparable measurements that reflect fabric behavior during tear propagation rather than initial tear initiation.
- Standardization context: Part of the ISO 13937 series addressing tear properties of fabrics; adopted by CEN and published as a national standard in member countries.
Applications
- Quality control for apparel and home textiles where tear propagation affects product durability and consumer safety.
- Performance testing for technical and industrial textiles (e.g., tarpaulins, upholstery, protective fabrics) where continued tearing is a failure mode.
- Comparative evaluation during material selection and R&D to compare weave constructions, yarn types, or finishing treatments regarding their resistance to tear propagation.
- Laboratory testing in textile testing houses, third-party certification bodies, and in-house QC departments that require standardized, reproducible tear-force data.
- Useful input for designers, engineers, and compliance teams concerned with lifecycle performance, warranty claims, and regulatory requirements.
Related Standards
- EN ISO 13937-3:2000 is one part of the broader ISO 13937 series on tear properties of fabrics; other parts address alternative tear test methods and specimen types. For a complete assessment of tear performance, consult the related ISO 13937 parts and relevant national/adopted CEN documents.
