COF friction tester measures the static and kinetic COF of plastic films, sheets, rubber, paper and paper board, PP woven bags, fabrics, metal-plastic composite belts for communication cables, convey belts, wood, coatings, brake pads, windshield wipers, shoe materials and tires. It follows ASTM D1894 and ISO 8295 standard
.
.
The two samples are placed together. A long strip sample is fixed on the flat surface and another squared sample is applied force by a sled. The friction force is measured when they slip against each other.
