Test sample: Household appliances, printed circuit board.
The surface of the insulation is scratched by means of a hardened steel pin, the end of which has the form of a cone with an angle of 40°. Its tip is rounded with a radius of 0,25 mm ± 0,02 mm. Scratching through five pairs of conductive parts, including its interval, an interval should be subjected to the largest part of the potential gradient during the test. And the pin is held at an angle of 80°~ 85° to the horizontal and loaded so that the force exerted along its axis is 10 N ± 0,5 N. The scratches are made by drawing the pin along the surface of the insulation at a speed of approximately 20mm/s±5mm/s. Two parallel scratches are made. They are spaced sufficiently apart so that they are not affected by each other, their length covering approximately 25 % of the length of the insulation. Two similar scratches are made at 90° to the first pair without crossing them.
The scratches shall be at least 5 mm apart and at least 5 mm from the edge of the specimen.
The device adopts PLC + touch screen control system, stepping motor drive, the scratch distance, scratch times and speeds can be preset, the test pin can rotate 90 ° angle automatically, scratch test in both vertical and horizontal directions can be easily realized.
