Precision instrument for measuring bendability in accordance with standards for flexible materials (metal and plastic foils, cardboard, paper etc.; max. thickness 3 mm). Outstanding good measuring accuracy (up to 0.1 %) achieved with motorized measuring process. Analogue and digital versions available, with accessories covering a total measuring range of 0.01 – 10.000 Stiffness Units.
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.
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.
