GB/T 3917.2-2009Textile -- Tear properties of fabrics -- Part 2: Determination of tear force of trouser-shaped test specimens (Single tear method) (English PDF)

1 Scope

This Part of GB/T 3917 specifies a single-tear method to determine fabric tear force, known as the trouser test, using a test specimen cut to form trouser-shaped legs. The tear force measured is the force required to propagate a previously started single tear when the force is applied parallel to the cut and the fabric tears in the direction of applied force.

This Part is mainly applicable to woven textile fabrics. It may be applicable to fabrics produced by other techniques, e.g. to some nonwovens, etc.

This Part is not applicable to knitted fabrics and woven elastic fabrics. It is not suitable for highly anisotropic fabrics or loose fabrics where tear transfer from one direction to another direction of the fabric during the tear test is likely to occur.

The part only allows the use of constant-rate-of-extension (CRE) testing machines.
