ASTM D202 Coefficient Of Friction Tester – Precise COF Measurement for Material Testing

Introduction to ASTM D202 Coefficient Of Friction Tester

The ASTM D202 Coefficient Of Friction Tester is a high-precision testing instrument designed to evaluate the static coefficient of friction (COF) of various materials, including plastic films, rubber, paper, paperboard, PP woven bags, fabrics, metal-plastic composite belts, conveyor belts, wood, coatings, brake pads, windshield wipers, shoe materials, and tires. By adhering to the ASTM D202 standard, this Inclined Plane COF Tester ensures reliable and repeatable friction testing for quality control, research, and product development across multiple industries such as packaging, food, pharmaceuticals, automotive, and materials manufacturing.

Working Principle of the ASTM D202 Coefficient Of Friction Tester

The ASTM D202 Coefficient Of Friction Tester operates using an inclined plane method, where a test specimen is placed on an adjustable inclined surface. The incline is increased at a controlled rate of 1.5 ± 0.5° per second using an electric motor until the test specimen begins to slide. The system automatically locks the inclined plane at the precise angle of movement initiation, allowing users to accurately measure and calculate the COF. The coefficient of friction is determined by the tangent of the slide angle, which is displayed in real-time on the digital control interface.

This method is widely utilized for determining the frictional properties of coatings, flexible packaging films, and industrial materials, ensuring optimal product performance and regulatory compliance.
