1.1This guide is intended to standardize the use of an inclined plane testing device to measure the breakaway friction (static) coefficient of mating couples that are of such size and shape that they can be made into a rider (one member of the sliding couple) on a flat surface (the second member of the sliding couple) that can be inclined at an angle to produce motion of the rider. The tangent of the angle at which breakaway motion of the rider occurs on the angled plane is the breakaway or static coefficient of friction for that sliding couple.

1.2Units-The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard.

1.3This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
