This standard specifies methods for the determination of tear force of fabrics. This part of the standard describes a double tear method known as tongue test using a test specimen with a cut 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 applied force. If the tear does not proceed along the direction of the cuts the fabric shall be described as untearable in that direction by this test. The test is mainly applicable to woven textile fabrics. It may be applicable to fabrics produced by other techniques. The method only allows the use of constant rate of extension (CRE) testing machines.
