Damping of the oscillations of a pendulum resting on the coating material in accordance with the standards. Konig 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.
Pencils of various grades of hardness are moved over the painted surface at an angle of 45° to the horizontal with a force of 5 N, 7.5 N or 10 N (± 0.1 N). The pencil hardness is defined by those two grades of hardness the softer one of which just produces a writing trace while the next harder one leaves a perceptible scratch on the coating.
The motor-driven SCRATCH HARDNESS TESTER 430P 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. 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 to perform DIN EN ISO 2409, ASTM D 3359, JIS K 5600-5-6, SNV 37 111, VDA 621-411, ECCA T6, GME 60280, GMW14688 & many other test methods. Please contact us for further details.
Successful instrument for producing a cross cut pattern in the coating to be tested Besides the universally applicable single blade instrument with folding ruler. 5 special multi-cutter versions available for tests in accordance with the standards listed. ISO 2409, EN ISO 24091), JIS K 5600-5-6, EN 13523-64(formerly ECCA-T6), ASTM D 3359, VDA 621-411, DBL 5416, ISO 2409-1972, BS 3900:E6, NF T 30-038 (all withdrawn)
To establish the limiting extension of coating materials on sheet metal specimens by bending around a conical mandrel (1/8″ – 1 ” or 3 mm – 38 mm dia.). From the diameter of the mandrel at the point where the crack starts, the maximum relative extension of the coating can be calculated. With quick-clamping device for faster operation.
A robust instrument for gauging the degree of fineness-of-grind of liquid dispersions of pigments in the range 0 -15/25/50/100 microns. The substance is filled into the wedge-shaped grooves and drawn down with a blade. Rippling occurs at the point where pigments particles are bigger than the depth of the groove measured in microns.
