Taber Shear / Scratch Tester

Taber Shear / Scratch Tester

Tester to evaluate resistance to shearing, scratching, gouging, marring, scraping and engraving on a variety of flat, rigid specimens

Taber Shear / Scratch Tester is a motorised instrument for testing the resistance to scratching of materials. A sample plate rotates while a conical diamond point is pressed on the sample plate. The relation between the depth of the scratch and the applied (pre-set) pressure indicates the hardness.

Complies with virtually all relevant international standards such as Normen:
ASTM C217 / C217M • DIN 53 799 • DIN 66 861-4 • EN 438-2 • EN 13310 • EN 14323 • EN 14565 • EN 14688 • 0096Z-SEC-A000 (Honda) • 7710Z-SCC-9000 (Honda) • ISO 4586-2 • ISO 15695 • JIS K 6902 • Terrazzo 90322-9E-1 • TSL 2105G (Toyota) • TSL 3610G (Toyota) • UNI 9428
