Textiles. Tear properties of fabrics - Determination of tear force of tongue-shaped test specimens (double tear test) Ingestion-build-159183 g) Providers of training or1 Scope 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. The test is mainly applicable to woven textile fabrics. It may be applicable to fabrics produced by other
