Co efficient of friction tester designed to find both ‘static’ and ‘dynamic’ co-efficient of friction through a metal platform system. The platform is allowed to move at the specified speed through a drive mechanism, driven with the help of a screw driven by a geared fractional HP electric motor. A steel sled of specified size, weight and covered with a micro cellular rubber sheet is also provided. The smaller specimen is wrapped around the sled and the higher specimen is clamped to the top of platform. A load cell type dynamometer is provided for measuring force for moving the sled. Most suitable for checking the co-efficient of friction of rubber sheet, fabrics, leather, rexine, paper, thin films etc
