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.
