Scratch-tester Millennium
In accord width Standars ISO/EN 1071-3,
ASTM c1624, ASTM G171 and JIS R 3255
Scratch test instrument for adherence charaterization
and scratch resistance
for thin coatings and bulk materials.
The scratch-test method consists of scratching
on the surface with a diamond tip on which is applied a constant
or progressive load.
As
the scratching is done the sample move under the video system,
to examine the different finds of damage done by the tip and correlate
it with load applied.
This
standard method allows for comparison of different coatings, substrates,
thickness of coatings, preparations of surface before coating
and scratch resistance of bulk materials.
