Naval Undersea Warfare Center Division Newport United States
The Underwater Sound Reference Division USRD at the Naval Undersea Warfare Center Division Newport NUWCDIVNPT provides underwater acoustic measurement and calibration services to a diverse client base including other government laboratories, nongovernmental organizations, industry, and academia. Services provided by the laboratory are accredited per ISO 170252005 for the competence of testing and calibration laboratories. In addition, the National Institute for Standards and Technology NIST is coordinating with the USRD to appoint it as the U.S. designated institute DI for sound in water. Once designated, the USRD will provide traceability to the International System of Units SI through its measurement and calibration services for underwater acoustic measurements. Among its responsibilities as an accredited laboratory and prospective U.S. DI for sound in water, the USRD engages in a variety of activities related to its quality management system QMS and claimed measurement capabilities. Among these are internal audits, operator training, proficiency testing and other activities intended to maintain the laboratorys competence and to consistently deliver measurement and calibration services with known measurement uncertainties. This document is a report summarizing activities of the USRD related to its quality system and measurement capabilities throughout 2018 followed by a summary of activities planned for 2019.
