1.1 This practice covers the testing of the James Machine for reprocucibility and repeatability of static coefficient of friction, relative to a standard reference interface consisting of the working surfaces of Borco board and standard leather shoe sole material. The practice provides basis data on the stability of the James Machine to ensure accurate static coefficient of friction determinations over time and repeated use and for determining if the James Machine is mechanically calibrated and properly aligned.
1.2 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 and health practices and determine the applicability of regulatory limitations prior to use.
