This standard specifies a procedure to determine thetear forceof nonwoven textile fabrics using the trapezoid method. A rectangular specimen is marked and prepared so that it can be loaded in the grip faces at an angle, allowing a tear to propagate across the specimen.

For this test, it is important to have an increased test data rate to ensure the capture a high number of data points. This is because when individual fibers within the fabric fail, the data rate must be fast enough to catch these peaks.
