Georgia L. Harris, J C. Gust


This document has been developed for the NIST Technology Services, Weights and Measures Division (WMD) in order to establish and implement a quality system for the planning, implementation, analysis, and reporting of Proficiency Tests (PT) and Interlaboratory Comparisons (ILC) conducted within the WMD Measurement Assurance Program (MAP). This document provides the quality system to ensure that all Proficiency Testing and Interlaboratory Comparison activities within WMD are compliant with International Laboratory Accreditation Cooperation, ILAC G13:2000, Guidelines for the Requirements for the Competence of Providers of Proficiency Testing Schemes, ISO/IEC Guide 43-1:1997, Proficiency Testing by Interlaboratory Comparisons Part 1, Development and Operation of Proficiency Testing Schemes. This document specifies requirements to ensure that NIST WMD and associated delegates are technically competent to provide specific types of proficiency testing schemes as required by NISTIR 7082, Proficiency Test Policy and Plan (for State Weights and Measures Laboratories), 2004.
