The Dutch Standardisation Institute (NEN) is the repository of all official standards for products and services in the Netherlands. Standards are developed for specific sectors by NEN’s standards committees, whose members include representatives of the various interested parties, such as companies and consumers. NEN manages some 30,000 international (ISO), European (EN) and national (NEN) standards.
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 430 P-Smart 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 430P-Smart 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 possibilities 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. Using the SCRATCH HARDNESS TESTER 430 P-Smart, series testing can be conducted with much greater ease. The results of testing are reproducible and well-defined. Optionally with manually actuated/motor-driven loading force and manually actuated/automatic test panel turn. Operation, documentation and data management via ERICHSEN-App
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)
Available option is the CrossScan 295/XVI Automatic Cross Hatch Cut Rating System ; evaluation software; consists of a handy dome for placing on the crosshatch pattern to be evaluated; equipped with camera, LED lighting and potentiometer for intensity control of lighting (5% – 100%). The evaluation takes place via the included software (PC not included).
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.
