2017–2018 "Support for GULFMET key comparison of Zener voltage standards" project

Following a discussion at the 35th meeting of the JCRB on the issue of cross membership of Regional Metrology Organizations (RMOs) in the context of providing assistance to the newest RMO, GULFMET, it was agreed to set up a project to provide support for the organization of one of GULFMET's first key comparisons GULFMET.EM.BIPM-K11, a comparison of Zener voltage standards. This assistance will allow GULFMET to advance its status as an RMO. JCRB members affirmed that various RMO activities are open to GULFMET within the resources available to accommodate them, including RMO comparisons, RMO training initiatives, and attendance at RMO plenaries.

  • Status:
    • The comparison is coordinated by the Standards and Calibration Laboratory (SCL), Hong Kong.

      Participants of the comparison:

      • Emirates Metrology Institute (EMI), United Arab Emirates
      • National Measurement and Calibration Center - Saudi Standards, Metrology and Quality Organization (SASO-NMCC), Saudi Arabia
      • Institute of Metrology of Bosnia and Herzegovina (IMBIH), Bosnia and Herzegovina

      Comparison support group:

      • Korea Research Institute of Standards and Science (KRISS), Republic of Korea
      • BIPM

      The BIPM will participate in the measurements to link the results of the GULFMET comparison to those of the BIPM.EM-K11.a and BIPM.EM-K11.b comparisons.
      The comparison coordinator, Dr Steven Yang from SCL (Hong Kong), was on secondment to the BIPM voltage laboratory from 9 January to 13 March 2017 to work and share experience on the calibration of Zener voltage standards using Josephson voltage standards.

  • Dates:
    • The technical protocol has been approved and the measurements are planned for the period from June 2017 to March 2018.
