Test Method: SATRA TM5
This test method is intended to determine the ability of a material to hold stitches or clenched fastenings. The method is applicable to rigid and semi-rigid sheet materials, to rubbers and plastics, and to welts used in footwear manufacture.
A pair of holes is drilled through the material and a loop of wire of specified dimensions is threaded through them. The material is then fitted in a special clamp on a tensile testing machine and the force required to pull the wire through the material is measured. This force is then divided by the thickness of the material to give the stitch-tear strength of the material.
