Coefficient of Friction Fixture


The G1086 COF fixture is an integral part of a COF measurement system, typically including a motorized test stand and COF gauge. The G1086 can be used for a wide range of materials, ideal for conformance to ASTM D1894 and other relevant standards. Static and kinetic coefficients can be measured using the M5-2-COF gauge.

The fixture includes a large work table with sample clamp, level, 200 g sled, cable, and low-friction pulley. The fixture is compatible with most Mark-10 motorized force test stands and frames (some models require an adapter; see Ordering Information).
