Introduction to the metrology program
As part of the Measurement Standards Division, the Oregon State Metrology Laboratory maintains the primary and "working" standards of mass, volume, and length for the State of Oregon. These standards are directly traceable to the national standards maintained by the US Department of Commerce, National Institute of Standards and Technology (NIST).

The national standards of mass are traceable to the international 1 kg standard in Sevres, France. Utilizing precision equipment and test procedures in conjunction with these standards, the Metrology Laboratory provides calibration services to businesses, consumers, agencies, and institutions.

The Oregon Department of Agriculture, Measurement Standard Division's Metrology Laboratory just scored very high marks on an extensive "quality system" and "management requirements" audit performed by National Voluntary Laboratory Accreditation Program (NVLAP). This audit addressed accreditation and compliance requirements prescribed by the American National Standards Institute (ANSI), the National Conference of Standards Laboratories (NCSL), the International Organization for Standardization (ISO), the International Electrotechnical Commission (IEC), and the National Institute of Standards and Technology - Handbook 150 (NIST). This high level of accreditation ensures that the MSD Metrology Laboratory will be able to perform the high level precision weights and measures calibration required in today's high technology business sector.
