 Scratch
Hardness Tester 239
|
|
| acc.
to Clemen |
 |
A weight loaded blade or ball shaped carbide tool is applied with a defined
force (0 - 20 N) to the specimen which is moved with constant speed.
The scratch hardness is measured by the force necessary to cut through
the coating to the substrate. Available for manual or motorised drive.

Indentation
Hardness Tester 263 |
|
| acct.
to Buchholz - ISO, BS, DIN, NF, ECCA |
 |
A steel block with circular indented inserts is applied onto the test
surface and produces a pressure mark, the length of which is measured
with a microscope. The impression hardness in accordance with Buchholz
is established from the length of the impression, using the standard
table.

 |
Pencils of increasing hardness are pushed across the surface of the coating
at a defined angle and under a defined load. The film hardness is
established by the two hardness grades between which there is a limiting
effect of surface marking and indentation into the surface.

Pendulum
Hardness Tester 299/300 |
|
| ISO,
ASTM, BS, DIN, NEN, SIS, SNV |
 |
Damping of the oscillations of a pendulum resting on the coating material
in accordance with the standards. Koenig and Persoz pendulum interchangeable.
Dust cover included in the basic unit. Optional accessories: Opto-electronic
counter with acoustic signal at test end with manual or automatic
deflection of pendulum.
