The rules of the CIPM MRA require that the NMIs implement and operate a Quality Management System (QMS) complying with the requirements of the ISO/IEC 17025 standard to support their calibration activities. Peer review will cover QMS in general, as well as calibration capabilities in the field of laboratories with implemented QMS of three partners: INM-MD, IMBiH and UME. Technical experts from UME and IMBiH will carry out on-site peer review of INM-MD and vice versa where applicable, in accordance with the requirements of the CIPM 2007-25 document and EURAMET “Guide for On-site visits by peers in the frame work of CIPM MRA“ (G-TCQ-PRC-006). Peer review is scheduled to start in December 2019. The first results of peer review will be reported to EURAMET TC-Q during annual meeting in 2020. This project is intended to be on-going.
