This practice describes the procedure for operating and verifying the calibration of an inertial profiling system. This practice is meant to be performed as a Quality Control/Quality Assurance (QC/QA) test for use with the appropriate smoothness specification for paving operations. It is not meant to be required as a QA procedure to monitor daily paving operations; however, this method is recommended when inertial profiling systems are used for QC testing and for network level data collection.

This standard was formerly designated as provisional standard PP 50.
