Understanding the Inclined Plane Coefficient of Friction Tester

Friction testing is essential for industries that rely on precise material handling, such as packaging, paper, and textiles. The Inclined Plane Coefficient of Friction Tester provides accurate static COF measurements, ensuring materials perform as expected under real-world conditions.

This tester determines the angle at which a material begins to slide against another inclined surface as the incline increases at a controlled rate. The static COF value is numerically equivalent to the tangent of that angle, ensuring a precise and repeatable evaluation of material properties.

Testing Standard

To ensure accuracy and compliance with international quality standards, dynamic coefficient of friction testing is performed according to ASTM D202 and TAPPI T815. While static COF determines the initial resistance to motion, dynamic coefficient of friction testing evaluates a material’s performance during movement. These standards ensure repeatable, standardized testing for friction analysis in industries such as flexible packaging and paper production.
