NIST Office of Weights and Measures – National Voluntary Laboratory Accreditation Program Partnership: New Faces and New Opportunities

The NIST Office of Weights and Measures (OWM) has long coordinated the accreditation of the State legal metrology laboratories through the OWM Recognition Program (NIST Handbook 143) in partnership with NIST’s National Voluntary Laboratory Accreditation Program (NVLAP). 


NVLAP Staff Changes



As many of you may know, Kari Harper was responsible for coordinating NVLAP’s support and accreditation of State legal metrology laboratory programs.  After over 30 years with NVLAP and NIST, Kari Harper has retired from Federal service effective December 31, 2022.  We thank Kari for her many years of expert services to NIST and the laboratory metrology community and wish her well in her new season of life. 



NVLAP welcomes Robert Knake as the new NVLAP coordinator to the Recognition Program.  Robert Knake was president of NCSLI from 2021 to 2022 and brings a rich background in serving as Calibration Program Accreditation Manager.  We congratulate Robert on his new role and look forward to future communications regarding the accreditation program and his engagement at the Regional Measurement Assurance Program (RMAP) meetings.     


OWM Coordination with NVLAP and State Laboratories


OWM’s coordination with NVLAP has been its contribution to the legal metrology community to achieve national uniformity in measurement practices across the states with review and acknowledgement at the highest level.  The OWM Recognition program operates similar to the NVLAP accreditation program by annually assessing participating laboratories in accordance with ISO/IEC 17025.  But unlike the NVLAP accreditation program, the OWM Recognition program ..
