This standard specifies methods for the determination of tear force of fabrics. This part of the standard describes a single tear method known as wing test using a test specimen cut to form two wings for clamping inclined at defined angle to the thread direction. The tear force measured is the force required to propagate a previously started tear. If the tear does not proceed along the direction of the cut 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. Due to the clamping of the specimen wings inclined to the threads to be thorn the test can be used for most types of fabrics without causing a transfer of tear and it is less susceptible to withdrawel of treads than other tear tests. The method only allows the use of constant rate of extension (CRE) testing machines.
