SATRA TM31 Martindale Abrasion Tester

Test  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 dry and

half wet. The relative movement between the abradant and specimen is a complex cyclic

pattern (a Lissajous figure) which produces rubbing in all directions. The test is stopped

after a prescribed number of cycles and the damage to the specimen assessed subjectively.

The severity of the test can be changed by varying the total number of abrasion cycles and

the contact pressure between the test specimen and the abradant.

According to the standard

This tester is manufactured according to SATRA TM31 and other standards.
