Significance and Use

5.1 Guide G115 lists a number of ASTM International standards that use the inclined plane test rig to measure the static coefficient of specific tribosystems. This guide applies to any material couple that can be made into test specimens; one being in the form of a rider and the other a plane that can be angled to produce motion of the rider on the plane. Footwear on walkway surfaces is an example of a very important application. Flooring surfaces that are slippery to various types of footwear can produce accidents and testing should be done on candidate flooring surfaces and candidate shoe soles and heels to quantify their relative slip resistance. This guide shows how an inclined plane can be used to make such a comparison.

5.2 The inclined plane method is also very useful in machine design in which parts of components shall slide unassisted down chutes and the like. An inclined plane test can be used to determine the chute angle that is needed to allow motion on all parts that are placed on the chute. The applications are numerous.

Scope

1.1 This guide is intended to standardize the use of an inclined plane testing device to measure the static (breakaway) coefficient of friction between two bodies. One body is in the form of a small “rider” (few centimeters) and the other a rectangular flat plane (50 mm to 75 mm by 400 mm). The rider is placed on the plane and the plane is inclined at an angle to produce motion of the rider. The tangent of the angle at which macroscopic motion of the rider initiates on the angled plane is the breakaway or static coefficient of friction for that sliding couple.

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

1.3 This 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.

1.4 This 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.
