Stitch Tear – Upper and Lining
This test is used to measure the breaking strength of stitched seams in upper and lining materials. Timberland requirements are currently based upon the standard test specimen as described in SATRA test method TM 180. Results are expressed as the load, both in pounds and kilograms, required to fail the standard test specimen. Therefore, results for specimens whose size differs from that of the standard will need to be adjusted. For instance a specimen that is twice as wide will theoretically have a failure load twice as big.
