PLC Automatic Abrasion Resistance Teste
. Application The abrasion resistance tester is applied for Scratch testing on solid insulating accessible parts or printed boards used in household appliances and similar products to ensure that the material has sufficient strength not to be pierced by sharp tools. 2. Introduction Abrasion resistance tester is designed according to IEC60950 clause 2.10.8.4 and IEC60335-1 clause 21.2. It is applied to do scratch test for accessible parts of solid insulation of household appliance and printed circuit boards, to ensure the material has sufficient strength to prevent penetration by sharp implements. The scratch resistance test uses a hardened steel pin for scratching. The end of the steel pin should be tapered with a apex angle of 40°. The tip should be rounded with radius of 0.25 mm ± 0.02 mm. When performing the scratch test, the test pin is held at 80-85° to the horizontal, scratches were performed at a speed of 20 mm/s ± 5 mm/s in a plane perpendicular to the edge of the conductor. The steel pin should be properly loaded so that the hardened steel pin can apply a force of 10N ± 0.5N along its axial direction. The scratch interval should be at least 5mm and at least 5mm away from the edge of the sample. This equipment adopts the control system of PLC+ touch screen, and the performance is stable. Rotating the work surface makes it easy to realize the scratch test in both directions. 3. Specification
