4 Test Station SATRA TM31 Martindale Abrasion Tester with 44mm Abrasion Heads

4 Test Station SATRA TM31 Martindale Abrasion Tester with 44mm Abrasion Heads

I.Introduction

1. Application:

This machine is suitable for testing footwear materials, fabric and coated fabrics. It can determine the resistance of a material to wet and dry abrasion.

2. 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.

3. According to the standard:

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

II. Features

Samples are rubbed against known abradent at low pressures, its degree of abrasion and can be compared with standard parameter evaluation.

The instruments used movable fastening components of the sample, you can always check out a sample of friction without affecting the other specimen

The tester is equipped with electronic preset batch counter, timer and pooled sample clips and load device (compatible with international testing standards) Provides 4, 6, head of the model.
