ABRASION TESTER

(DIN 53516)

A cylindrical test specimen of prescribed dimensions is drawn across a test emery paper with corundum of 60 grades at a constant force of application of 10 N and at a constant speed of 0.32 m/s, the abrasion distance being 40 m or in special cases 20m. An abrasive powering the range from 170mg to 220mg is allowable. The loss of mass of the test specimen in mg is determined to within 1mg by weighing and its volume loss calculated on the basis of the density determined according to DIN 53 479. The test procedure according to standard DIN 53516, provides a measuring method for assessing the resistance of elastomers to wear by rubbing. The determination of the volume loss by rubbing with a test emery of defined abrasive power by this method is suitable for comparative testing, for checking the uniformity of specified products and for specifications; however, the results of this test gives only limited information on the wearing behavior of elastomers in practice
