Abrasion Strength Resistance Testing Machine IEC60335-1 clause 21.2
Product information:
The device is used to check abrasion strength of printed circuit boards or the insulating accessible parts of the household appliances.
It conforms to the standard requirement of IEC60950 clause 2.10.8.4 and IEC60335-1 clause 21.2.
Technical parameters:
| Input voltage | 230V/50Hz |
| control system | PLC + touch screen |
| Drive mode | stepper motor-driven |
| Scratching speed | 0-25mm/s adjustable |
| Testing times | 0-9999times,it can be preset |
| Scratching distance | Adjustable |
| Working table | 360° rotatable |
| Scratching pressure | 10N±0.5N, it can be equipped with the weight of 20N to reach the scratching pressure of 30N±0.5N |
| Radius of Steel Pin | 0.25±0.02mm |
This device adopts a hardened steel pin for scratching.
The end of the pin is form of a cone having a tip angle of 40°, its tip being rounded and polished, with a radius of 0,25 mm ± 0,02 mm. Scratches are made by drawing the pin along the surface in a plane perpendicular to the conductor edges at a speed of 20 mm/s ± 5 mm/s. The pin is so loaded that the force exerted along its axis is 10 N ± 0,5 N.
The scratches shall be at least 5 mm apart and at least 5 mm from the edge of the specimen.
Scratches are made across five pairs of conducting parts and the intervening separations at points where the separations will be subject to the maximum potential gradient during the tests.
