20mm/s Abrasion Strength Tester Household Appliance Test Equipment

Household Appliance Test Equipment Abrasion Strength Tester With 20 mm/s Speed

Standard:

IEC 60335-1 ‘Household and similar electrical appliances – Safety – Part 1: General requirements’ clause 21.2

Application:

The device is used to check abrasion strength of printed circuit boards or the insulating accessible parts of the household appliances. Household Appliance Test Equipment.

Used to test whether the accessible parts of solid insulation have sufficient strength to prevent penetration by sharp implements.

Feature:

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°. Its tip is rounded with a radius of 0.25 mm ± 0.02 mm. The pin is held at any angle from 80° to 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 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° to the first pair without crossing them.
