2017 - CBKT Project: Support to GULFMET on Zener key comparison (CBKT-EM-GULFMET)

Overview

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.

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

Participants of the comparison:

• EMI, United Arab Emirates
• SASO-NMCC, Saudi Arabia
• IMBIH, Bosnia and Herzegovina

Comparison support group:

• KRISS, Republic of Korea
• BIPM

The BIPM participated 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 BIPM also determined the temperature and pressure correction coefficients of the transfer standards to compare with those determined by the coordinating laboratory.

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.
