DIN Abrasion Rubber Testing Machine With DIN-53516 / ISO-4649
DIN Abrasion Rubber Testing Machine With DIN-53516 / ISO-4649
Purpose:
DIN Abrasion Tester for flexible materials,rubber,tires,conveyor belts,shoe soles,soft leather,leather. . . Qualitative measure of wear and other materials,with high efficiency,good reproducibility and easy operation characteristics .
Principle:
At a predetermined contact pressure and a given area , the sample and the sandpaper into a certain angle,the measurement sample at a certain level of friction generated on the abrasive wear resistance .
Sandpaper attached to the surface of the roller package,the sample is pressed against the drum with the sandpaper,so that the lateral movement of the drum sample .
Wear the sample in the cylindrical end of the generation,measurement value of the sample mass loss,calculate the volume density of the sample by the amount of wear .
According to the standard:
This instrument reference standard : DIN-53516 , ISO-4649 , GB / T 9867 .
