ASTM E2883-13(2019)

1.1 This guide describes the evaluation and calibration of friction measurement systems which are known as Continuous Friction Measuring Equipment (CFMEs). The evaluation and calibration processes, using the specialized equipment, instruments, pavement surfaces, trained personnel, and approved facilities, are performed using the procedures described below.

1.2 This guide is offered as a process to identify and quantify the variables that affect system performance, to minimize the effect of these variables, and to provide a means to relate CFMEs to reference skid measurement systems.

1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.4 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.

1.5 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.
