This Part of EN ISO 13937 describes a double-tear method known as the tongue test, using a test specimen with cuts shaped to form a tongue. The tear force measured is the force required to propagate the previously started double tears when the force is applied parallel to the cuts and the fabric tears in the direction of the applied force.

Overview

SIST EN ISO 13937-4:2000 is an important international standard that specifies a test method for determining the tear force of textile fabrics using tongue-shaped test specimens, commonly referred to as the double tear test. Published by the Slovenian Institute for Standardization (SIST) and aligned with ISO 13937-4:2000, this standard provides a consistent procedure for assessing the tear properties of woven and non-woven fabrics. Understanding and measuring the tear strength of textiles is essential for evaluating their durability and performance, particularly for applications where fabric integrity is critical.

Key Topics

Tongue Test Method: The standard describes a method where a tongue-shaped specimen is cut from the fabric. A force is applied parallel to the pre-cut lines, and the force needed to continue tearing the specimen is measured.

Double Tear Test: This method evaluates the force required to propagate two tears simultaneously, offering a reliable measure of fabric resistance to tearing.

Test Consistency: By standardizing procedures, the test ensures comparability of results across different materials, laboratories, and applications.

Measurement of Tear Propagation: The focus is on the force required to propagate an initiated tear, which is often more relevant for end-use performance than the force required to initiate a tear.

Applications

The guidelines and methods outlined in SIST EN ISO 13937-4:2000 are widely applied in the textile industry and research settings. The double tear test is particularly useful for:

Quality Control: Ensuring textile fabrics used in garments, upholstery, technical textiles, and industrial applications meet durability requirements.

Product Development: Evaluating and comparing the tear resistance of new fabric constructions and finishes.

Compliance and Certification: Demonstrating compliance with international safety and durability standards for textiles.

Performance Assessment: Supporting decision-making for the selection of fabrics in sectors where resistance to tearing is essential, such as outdoor equipment, uniforms, and workwear.

This standard is intended for laboratory use and can be applied to most textile fabrics, regardless of their construction or fiber type.

Related Standards

Several standards are closely linked to SIST EN ISO 13937-4:2000 and provide a broader framework for textile tear strength testing:

EN ISO 13937-1: Textiles - Tear properties of fabrics - Part 1: Determination of tear force using the Elmendorf method.

EN ISO 13937-2: Textiles - Tear properties of fabrics - Part 2: Determination of tear force of trouser-shaped test specimens.

EN ISO 13937-3: Textiles - Tear properties of fabrics - Part 3: Determination of tear force of trapezoid-shaped test specimens.

ISO 9073-4: Textiles - Test methods for nonwovens - Part 4: Determination of tear resistance.

General textile testing standards: These offer additional methodologies for assessing other mechanical and physical properties of fabrics.

Summary

SIST EN ISO 13937-4:2000 provides a robust, internationally accepted method for measuring the tear force of textiles using a tongue-shaped specimen in a double tear test. This standard is essential for ensuring fabric performance, aiding in product development, and supporting compliance with quality and safety standards in the global textile industry. Adhering to this method helps manufacturers, laboratories, and researchers ensure that textile products are fit for purpose and meet market expectations for durability and reliability.
