The OWM Laboratory Metrology Program manages a Laboratory Recognition service that originally began as a congressionally mandated "New State Standards Program" in 1965 as part of its continuing support to the states. This service is designed to provide recognition of state metrology laboratory programs according to the technical specifications in NIST Handbook 143 and ISO/IEC 17025. The recognition service also includes technical and administrative guidance and training, proficiency testing, and assistance to state legal metrology laboratories to ensure accurate and traceable measurements from NIST standards, measurement services, and metrology training to the local jurisdictions.
A series of documentation resources (listed in the table below) are primarily developed for state weights and measures programs and state metrology laboratory staff. The technical criteria that are applicable for all state weights and measures laboratories as referenced as specific sections in the current version of NIST Handbook 143 and ISO/IEC 17025.
