IEC 62368-1 Clause 5.4.1.5.3 Insulation Surface Scratch Resistance Test Apparatus

Production Information:

This Insulation Surface Scratch Resistance Test Apparatus meets the requirements of IEC 62368-1 clause 5.4.1.5.3, IEC 60335-2-78:31; IEC 60335-2-95:31; IEC 60335-2-97:31; IEC 60335-2-103:31; IEC 60335-1:21.2; IEC 60335-2-40:31, etc.

It is used to test the solid insulated parts that have been touched, coated with printed boards or coated component of household and similar appliances

Working Principle:

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 40^o. Its tip is rounded with a radius of 0,25 mm ± 0,02 mm. The pin is held at an angle of 80^o to 85^o 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 90^o to the first pair without crossing them.
