Friction Testing

Friction Testing Universal Testing Systems

Friction testing allows quality control professionals to determine the coefficients of starting and sliding friction of materials such as plastic films, sheeting, household items, conveyor belts, and more. ADMET material testing systems will accurately and reliably perform friction testing and automatically calculate properties such as the static coefficient of friction and the dynamic coefficient of friction. We offer universal testing systems equipped with coefficient of friction fixtures featuring a sliding plate and a sled for friction testing. The sliding plate dimensions as well as the sled surface material may be customized based upon your needs.

Common friction testing definitions and keywords include:

• Coefficient of friction: The ratio of the frictional force to the normal force, which are perpendicular to the two surfaces in contact.
• Static friction: The threshold to the resistance against sliding between two surfaces that are in contact with one another.
• Dynamic friction: Persisting friction force during a sliding motion at a given speed.

Below is a list of friction testing standards:

• ASTM D1894 – Standard Test Method for Static and Kinetic Coefficients of Friction of Plastic Film and Sheeting
• ASTM D5458 – Standard Test Method for Peel Cling of Stretch Wrap Film 
• ISO 8295 – Determination of Coefficients of Friction
• ISO 21182 – Light Conveyor Belts – Determination of Coefficient of Friction
