The Oklahoma Bureau of Standards is an agency of the Oklahoma State Department of Agriculture, Food, and Forestry. The purpose and authority of the Bureau of Standards, as defined in Title 2, Article 14, Section 14-1 through 14-7 of the Oklahoma Statutes, is to provide the highest level of calibration for weighing and measuring standards for the State of Oklahoma. The statute also states that the Bureau will be made available to all state departments, municipal and private corporations, and citizens of this state. Current areas of service include mass (Echelon I, II, and III), length (tapes and rigid rule), and volume (gravimetric and volume transfer).
The Bureau provides accurate traceable standards to both legal and private metrology clientele. Legal metrology customers consist of weights and measures regulatory agencies such as the Department of Agriculture, Food, and Forestry’s Weights and Measures Program along with the Corporation Commission’s Liquid Measuring Device (Motor Fuel) Program. Private enterprise sectors served by the Bureau include aeronautics, aerospace, automotive, biomedical, energy, environmental, healthcare, manufacturing, nuclear, petroleum, and pharmaceutical industry (research & development and quality assurance) together with investigative work when requested.
The metrology laboratory of the Bureau is a certified participant in the Measurement Assurance Program of the National Institute of Standards and Technology (NIST) and all calibrations and tests performed by the Bureau are traceable to NIST. State metrologists attend the annual regional quality assurance program meeting (SWAP) for training and analysis of interlaboratory comparison data. The Bureau meets the criteria in ISO/IEC 17025:2005, ANSI/NCSL Z540-1-1994 Part 1, and is accredited as a calibration laboratory by the National Voluntary Laboratory Accreditation Program (NVLAP Lab Code 200396-0).
