Abrasion Strength Testing Machine Abrasion ResistamceTester -
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.
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.
