Tear Resistance Test
The Tear Resistance test measures the force required to tear a sample material such as woven or nonwoven 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 D5587 Standard Test Method for Tearing Strength of Fabrics by Trapezoid procedure. Nelson Labs is an active member of ASTM committees.
Tensile testing measures the force needed to elongate and break a sample. It is used to determine the strength and elasticity of woven or nonwoven fabrics, plastic film or sheeting, gloves, condoms and other materials.
Nelson Labs tests fabrics by the strip method (EN 29073 or ISO 9073) or the grab test (ASTM D5034, D5035). Plastics are tested according to ASTM D882, ASTM D638. Fabrics are tested wet or dry. We are an active member of ASTM committees.
