Coefficient of Friction Testing of Plastics The coefficient of friction , or COF, is determined by the ease with which two surfaces slide against each other. The dimensionless value of the coefficient of friction is the ratio of the force required to slide the surfaces to the force perpendicular to the surfaces.

It’s even lower than the 0.42 minimum dynamic COF used as a safety criterion in ANSI A137.1 – but that DCOF is measured using the BOT-3000E digital tribometer.

ISO 8295 Coefficient of Friction Plastic Film and Sheeting

2810-005 Coefficient of Friction Fixture How to Perform a Test to ISO 8295 The ISO 8295 test method is used to investigate the static and dynamic frictional properties of film and sheet plastics when sliding against either itself or another material. Coefficient of Friction | Global Floor Safety NetworkCoefficient of Friction (COF) is defined as the friction force opposing sliding motion divided by the force normal to the surface. People walk differently (most people demand a consistent COF of between 0.25 – 0.3 walking normally) Long fast strides demand a higher friction. Although slippery surfaces or steep slopes provide low COF, we often
