Hardness Tester HGiB Shore A
The pocket testers are used predominantly for quick, mobile hardness testing to Shore A on elastomers, natural rubber products, cast resins, polyesters, plasticised PVC, neoprenes, leather and similar materials etc.
With this hardness testing method, a needle in the form of a blunt cone is pressed into the material to be tested. The size of the penetration resistance is displayed on a scale. The methods are standardised to DIN 53505, ASTM D 2240 Part 20 and BS 903.
The tester contains a test needle on which the spring force acts whose load increases for Shore A from 55 to 806.5 cN and for Shore D from 0 to 4450 cN when the needle which is initially protruding by 2.54 mm is pressed back by this distance.
During the test process, the tester is pressed jerk-free with the prescribed contact force against the material to be tested until the surface is flush. The hardness can be read off after approx. 3 seconds of contact between the tester and the material to be tested.
