IEC 60335-1 Clause 21.2 Insulation Surface Scratch Resistance Test Apparatus
Product Information:
The Insulation Surface Scratch Resistance Test Apparatus is designed and manufactured according to the standard requirements of IEC60335-1 clause 21.2 IEC60950 and clause 2.10.8.4 and etc. It is used to test the abrasion strength of printed circuit boards or the insulating accessible parts of the household appliances. The test sample including the solid insulated parts that have been touched, coated with printed boards or coated component of household and similar appliances.
The surface of the insulation is then scratched by means of a hardened steel pin, the end of which has the form of a cone with an angle of 40o. Its tip is rounded with a radius of 0,25 mm ± 0,02 mm. The pin is held at an angle of 80o to 85o 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 20 mm/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 90o to the first pair without crossing them.
