SCRATCH HARDNESS TESTER 430 P-I
Purpose and Application
The motor-driven SCRATCH HARDNESS TESTER 430 P is a universal testing instrument
designed for carrying out a wide range of tests on varnished and plastic surfaces to determine their
resistance to scratches and cuts. Single cuts, parallel cuts and – by turning the specimen by 90°
– cross-cuts can be applied to test panels of various thicknesses.
The SCRATCH HARDNESS TESTER 430 P is particularly provided for adhesion tests using the
cross hatch cut method (in accordance with all mostly required standards) and for specific
plastics tests according with Opel (scratch resistance and writing effect). For these as well as
for further tests numerous setting possibilites on the basic instrument and a large variety of test
tools are available.
Using the SCRATCH HARDNESS TESTER 430 P, series testing can be conducted with much
greater ease. The results of testing are reproducible and well-defined.
Design and Function
The SCRATCH HARDNESS TESTER 430 P is a benchtop instrument of sound mechanical
construction which provides reliable, well-defined cuts, even under extreme test conditions. The test
procedure is carried out automatically and all parameters (cutting speed, cutting stroke, crosscut
pattern) can be set using the keyboard. Each motion sequence (transport of test panel, cut
positioning and any required pressure adjustment) is driven by a separate step motor.
During the test the specimen is conveyed linearly and at a constant speed under the test tip which
has been set at the required pressure load (max. 40 N). A transmission guide ensures that the test
tip is lowered onto the test panel as defined. The scope of supply includes two control plates for
different cross-cut patterns which can be easily interchanged.
Various test tips are available.
