Abstract

This paper describes how the Process Measurement Assurance Program (PMAP) is used in the United States State metrology laboratories (weights and measures laboratories) to provide uniformity among the laboratories in measurement control, uncertainty evaluation, control charting, and assurance of standards accuracy and traceabiltiy. The program provides a method for electronic submission (via e-mail or diskette) of control charts and standards data in a standardized format for NIST, Office of Weights and Measures (OWM) evaluation. The methodology of PMAP and how it applies to a comprehensive quality management program for State metrologists can be applied to other metrology laboratories and systems.
