1.1 本指南旨在使倾斜平面测试装置的使用标准化，以测量两个物体之间的静态（分离）摩擦系数。一个身体是一个小的“骑手”（几厘米），另一个是一个矩形平面（50 毫米至75毫米乘400 mm）。骑车人被放置在平面上，并且平面以一定角度倾斜以产生骑车人的运动。骑车人在成角度平面上开始宏观运动的角度的切线是该滑动副的分离或静态摩擦系数。 1.2 单位-- 以国际单位制表示的数值应视为标准。 本标准不包括其他计量单位。 1.3 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 5.1 指导 G115 列出了一些使用倾斜平面试验台测量特定摩擦系统静态系数的ASTM国际标准。本指南适用于可制成试样的任何材料偶；一个是骑车人的形式，另一个是可以倾斜以产生骑车人在平面上的运动的平面。人行道表面的鞋类就是一个非常重要的应用实例。对于各种类型的鞋子来说，地板表面很滑可能会导致事故，应在候选地板表面以及候选鞋底和鞋跟上进行测试，以量化其相对防滑性。 本指南展示了如何使用倾斜平面进行此类比较。 5.2 斜面法在机器设计中也非常有用，其中部件的部件应在没有辅助的情况下滑下滑槽等。斜面试验可用于确定斜槽角度，该角度是允许放置在斜槽上的所有零件运动所需的角度。应用程序很多。

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. ====== 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.
