Test Method: SATRA TM95
Abrasion and snagging resistance - drum method
March 2020
SCOPE
This method is intended to determine the resistance of a material or a thread in a stitched seam to abrasion and snagging. It is applicable to all types of finished leather and coated fabric but can be used with any similar material. It is also applicable to all types of thread.
PRINCIPLE
Method 1 – Materials: A rectangular test specimen is bonded with an adhesive to the convex surface of a rigid stainless-steel cylindrical bar. The test specimen assembly is tumbled for a set time inside a hollow drum with standard granite chippings. The damage to the specimen is visually assessed by comparison with a standard damage scale and by making a general assessment of the loss of surface finish. If required, individual damage sites can be counted.
Method 2 – Threads: The test specimen thread is used to produce a lockstitch seam in a rectangular piece of corrected grain leather. The piece of leather is tested as in Clause 2.1 and after set intervals the damage to the seam is assessed by counting the number of broken stitches.
