Summary:
This Inclined Surface Coefficient of Friction Tester is a accurate instrument for determining the static friction coefficient of flat surfaces. It is professional applicable to the determination of static coefficients of friction of paper, paper board, plastic films, sheets, convey belts and other materials. By testing the frictional properties of materials, the open performance of packages, packing speed of packers and other indexes could be controlled to meet requirements for production.
The COF is measured on an inclined plane of approximately 0 to 85°. This incline is increased at a rate of 1.5±0.5° per second by an electric motor until the sample bearing block begins to slide. At this point, the inclined plane is locked and the angle can be read. The tangent of this angle is the coefficient of friction (COF)
Standards:
TAPPI T 815: Coefficient of static friction (slide angle) of packaging and packaging materials (including shipping sack papers, corrugated and solid fiberboard) (inclined plane method)
ASTM D 202: Standard Test Methods for Sampling and Testing Untreated Paper Used for Electrical Insulation
ASTM D4918: Standard Test Method for Coefficient of Static Friction of Uncoated Writing and Printing Paper by Use of the Inclined Plane Method
ETC..
