Underwater Sound Reference Division (USRD) Annual Report: 2019
Abstract
The Underwater Sound Reference Division (USRD) at the Naval Undersea Warfare Center Division, Newport is the institute designated by the National Institute of Standards and Technology (NIST) to hold national measurement standards for sound in water, to disseminate those standards in the United States, and to provide traceability to the International System of Units. Thus, the USRD resides at the top of the U.S. national metrology system within the limited scope of its designation the acoustic pascal in water. National measurement standards delegated to the USRD are disseminated through the laboratory's calibration services to industry, government, and academic institutions in the United States and internationally. As a NIST designated institute, the USRD must conform to the requirements of ISO/IEC 17025 and maintain its accreditation through periodic assessment of the laboratory by the National Voluntary Laboratory Accreditation Program. The laboratory engages in activities required by its quality management system and claimed measurement capabilities, including internal audits, operator training, proficiency testing, and other activities intended to ensure the consistent delivery of calibration services with known measurement uncertainties. This report summarizes the activities of the USRD related to its quality system and measurement capabilities throughout 2019, followed by a summary of activities planned for 2020.
