For tests in accordance with all salt spray standards. Corrosion resisting test chamber with circular dome or rectangular chamber, of plastic construction. Special dimensions upon request. Operator friendly controls for up to 2 test chambers with volumes of 400 l and/or 1000 l.
Corrosion test apparatus for standardized tests in condensation water climate with or without SO2 addition. The functions “heating”, “gas dosing”, “draining” and “venting” are controlled by a programmable timer.
Inexpensive apparatus for testing the corrosion resistance of specimens in condensation water climate with or without SO2 addition in accordance with different standards. Robust 300 l plastic chamber with front door loading. A larger version with 1000 l test chamber volume can be supplied in special design.
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.
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
For tests on coatings for crack formation, breaking off, adhesion and elasticity. A bulge is formed in the sheet metal by a falling weight with a hemispherical end. The coating can be on the outside or on the inside of the bulge. The energy of blow can be varied either by using different heights of fall or different dropping weights.
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)
Lever-type instrument for testing the flexibility and the adhesive properties of coatings when these are subjected to bending stresses. With 14 easy exchangeable mandrels (diameter 2 – 32 mm). Testing with the cylindrical mandrel bending tester determines the greatest cylinder diameter at which a coating will show cracking or flaking subsequent to bending. Model 266 S allows the testing of samples up to a width of 100 mm.
