Test Method: SATRA TM31

Abrasion resistance - Martindale method

November 2021

SCOPE

This method is intended to determine the resistance of a material to dry and wet abrasion. The method is mainly applicable to fabrics, coated fabrics and leathers but it can be used with any flexible sheet material.

PRINCIPLE

A number of circular test specimens are rubbed against pieces of a standard fabric abradant under a constant contact force, with half the number of abradant pieces being tested dry and half after wetting (some specifications may only require only dry or only wet testing). The relative movement between the abradant and specimen is a complex cyclic pattern (a Lissajous figure with only one cycle comprising sixteen revolutions) which produces rubbing in all directions. The test is stopped after a prescribed number of revolutions and the damage to the specimen assessed subjectively. The severity of the test can be changed by varying the total number of abrasion revolutions and the contact pressure between the test specimen and the abradant.
