Overview
EN ISO 13937-1:2000 - Textiles - Tear properties of fabrics - Part 1: Determination of tear force using ballistic pendulum method (Elmendorf) - describes the Elmendorf (ballistic pendulum) method for measuring the tear force required to propagate a single-rip tear of defined length when a sudden force is applied. The method is primarily intended for woven textile fabrics and may be applied to other fabric types (for example, nonwovens) with the same restrictions noted for woven constructions.
Key Topics
- Test principle: Use of a ballistic pendulum (Elmendorf) to apply a sudden force that propagates a single-rip tear from a pre-cut in the specimen.
- Specimen preparation: Defined cutting of the fabric and preparation of a consistent initial tear length (as specified in the standard).
- Apparatus requirements: Description of the Elmendorf pendulum test equipment, calibration and maintenance essentials.
- Measurement and calculation: Converting the pendulum’s measured energy loss or deflection into tear force values and recording results.
- Applicability and limitations: Main applicability to woven fabrics; conditional applicability to fabrics produced by other techniques (e.g., nonwovens) with restrictions.
- Reporting and documentation: Required test results, conditions and any deviations to ensure reproducibility and comparability.
Applications
EN ISO 13937-1:2000 is used wherever accurate assessment of fabric tear resistance under a sudden loading is required:
- Quality control and factory acceptance testing for apparel, upholstery, home textiles, and technical textiles
- Material selection in product development and R&D to compare tear performance
- Safety and performance evaluation for protective clothing and automotive interiors
- Comparative testing in textile research laboratories and accredited testing facilities
Who uses this standard
- Textile manufacturers and converters performing routine quality assurance
- Independent textile testing laboratories
- Product designers and R&D teams evaluating material durability
- Specifiers and procurement teams setting minimum performance criteria
- Standards bodies and certification organizations referencing tear performance
Related Standards
- ISO/EN standards covering other tear test methods (for example, ISO 13937-2 - trouser test) and complimentary tensile and elongation standards used together to build a full mechanical profile of textile fabrics.
