After receiving feedback from end-users regarding the implementation of Standard Test Method for Evaluating the Performance of Systems that Measure Static, Six Degrees of Freedom (6DOF), Pose (ASTM E2919-13), it was determined that the description of the use of the F-statistic was in error in Section 9.2.6 and the data collection process could be simplified without impacting the statistical significance of the evaluations. With the assistance of Philip Freeman from Boeing, the data collection process defined in Section 9.2.6 has been revised. Specifically, the requirement for a minimum of four (4) to a maximum of 30 repetitions, with each repetition consisting of 32 random pose measurements, was changed to reduce the total number of random pose measurements from 4x32=128 to only 32 random pose measurements. The user still has the option of performing more than 32 random pose measurements if they so choose. The proposed changes will make the standard simpler and significantly easier to implement. The changes made to Section 9.2.6 impact other sections by making some variables and data collection procedures obsolete so affected sections have been revised accordingly. These changes are reflected in the included redlined draft version of the standard test method. To expedite the revision process, we request that only the changes made to ASTM E2919-13 be balloted, as the test method remains largely unchanged.
