Standard Outfit: 1 steel stylus as scratch tool, hardened, lower end tapered with a bevel angle of 40°and a radius of 0,25±0,02mm at its tip, 1 linear sliding carriage, with free-moving guideway for the steel stylus in a vertical plane with an angle of 80°~85° between the longitudinal axis of the steel stylus and the horizontal, 1 weight piece to weight the steel stylus so that the force in the direction of the steel stylus axis is 10N±0,5N, 1 drive for moving the sliding carriage by its full travel of approx 140mm at speed of 20±5mm/s, the scratches shall be at least 5 mm apart and at least 5 mm from the edge of the specimen. 1 specimen support for specimens with max, dimensions: length approx.200mm,width approx.200mm, height approx. 6mm, 1 operation manner: touch screen controllerSpecial outfit: pressure test device, for after scratch test, the hardened steel pin is then applied perpendicularly with a force of 30N±0,5N to an unscratched part of the surface. The insulation shall then withstand the electric strength test of IEC60335-1 clause 16.3 with the pin still applied and used as one of the electrodes. Power supply: 220V50Hz other voltages request.
