iec60950 scratch abrasion resistance test apparatus 

Appliance :

This device complies with the standards of IEC 60335-1: 21.2, GB4706.1: 21.2, IEC60950: 2.10.8.4, GB4943-2001: 2.10.6.6. Is used to detect the solid insulation of household and similar electrical appliances to prevent sharp tool piercing strength test.

Technical performance:

Coating scratch resistance test using hardened steel needle to be scratched, the end of the needle should be a cone, the vertex angle of 40 °, the tip should be rounded, round radius of 0.25mm ± 0.02mm.Scratches through the five pairs of conductive parts, including the middle interval, the interval should be tested to withstand the maximum potential gradient of the site.

In the case of a scratch test, scratches were carried out at a speed of 20 mm / s ± 5 mm / s in a plane perpendicular to the edge of the conductor. The needle should be fitted with an appropriate load so that the needle can exert a 10N ± 0.5N force along its axis. The scoring interval should be at least 5 mm and at least 5 mm from the sample edge.

The machine uses PLC + touch screen control system, stable performance; rotating work surface, easy to achieve vertical and horizontal scoring test in both directions.
