The Tear Resistance test measures the force required to tear a sample material such as woven or non-woven fabrics, and plastic film or sheeting. This test allows manufacturers to determine the strength of the sample.
This test complies with the following standards: ASTM D1004 Standard Test Method for Initial Tear Resistance of Plastic Film and Sheeting, WSP100.2 (INDA/EDANA) Standard Test Method for Tearing Strength of Nonwoven Fabrics by Trapezoid Procedure, and ASTM D 5587 Standard Test Method for Tearing Strength of Fabrics by Trapezoid procedure. Nelson Laboratories is an active member of ASTM committees.

Study OutlineIn the Tear Resistance test, plastic samples are cut using the ASTM D1004 C die and the average of several thickness measurements is reported. The instrument is set up with the crosshead speed to 2 inches per minute and the specimen is inserted into the grips. The maximum load in pound force for the specimen is reported.
Fabric samples are cut to 3 x 6 inches. The instrument is set to 12 inches per minute and the specimen is inserted into the grips. The maximum load in pound force is reported.
