National Voluntary Laboratory Accreditation Program (NVLAP) Accreditation to ISO/IEC

The ORNL Metrology Laboratory maintains a quality assurance program based on the International Standards Organization’s (ISO) standard ISO/IEC 17025.  ISO 17025 is a comprehensive standard that addresses the quality aspects of the operation of calibration and testing laboratories and is recognized internationally by both industrial and research organizations.  A properly implemented ISO 17025 quality program ensures the quality of calibration services by addressing the entire calibration process including organization of the management system of the laboratory, the training of the technical personnel, traceability and maintenance of standards, control of the laboratory environment, generation, technical requirements for a calibration, and maintenance of documents and handling of non-conformances.

Additionally, the ORNL Metrology Laboratory achieved accreditation to the requirements of the ISO 17025 standard, thus verifying the standard is wholly integrated into the daily operations of the laboratory.  The ORNL Metrology Laboratory chose the National Institute of Standards and Technology’s (NIST) National Voluntary Laboratory Accreditation Program (NVLAP) as its accrediting organization and program.  The ORNL Metrology Laboratory is accredited by NVLAP in multiple calibration disciplines after an extensive evaluation including: on-site assessments, technical evaluations, and participation in proficiency tests.  Those accredited disciplines are clearly identified in the ORNL Laboratory’s NVLAP Scope of Accreditation and Certificate. The ORNL Metrology Laboratory is ever expanding its accredited scope.

In addition to NVLAP-Accredited calibrations, the ORNL Metrology Laboratory also provides calibrations in several non-accredited areas.  For those areas, the same quality system is utilized; however, the area has not been formally assessed by NVLAP for accreditation.  All calibrations are performed using NIST-traceable standards and will be provided with estimates of uncertainties.

When requesting a quote for calibration from the ORNL Metrology Laboratory, please specify whether or not a NVLAP-accredited calibration is required.

Any reference to “accredited” or “accreditation” refers to the National Voluntary Laboratory Accreditation Program (NVLAP) and applies to calibration services only as performed by the Oak Ridge National Laboratory’s (ORNL) Metrology Laboratory (Lab Code 200159-0). Refer to the ORNL NVLAP scope of accreditation for details.”
