Introduction and Scope of the Transition Policy and Plan

The International Organization for Standardization (ISO) has published ISO 17034:2016 on the general requirements for the competence of reference material producers (RMPs) on  November 1st 2016. Previously, these requirements were addressed in ISO Guide 34:2009 originally developed by the ISO Committee on Reference Materials (ISO/REMCO). 

On the other hand, on  November 30th 2017 the Standard ISO/IEC 17025:2017 “General requirements for the competence of testing and calibration laboratories” has been published by ISO, replacing the previous version ISO/IEC 17025:2005.

These standards form the basis for expert assessments of quality management systems (QMS) of national metrological organizations (NMI/DI) in regional metrological organizations, in particular in COOMET.

This document defines responsibilities and obligations, actions with respective timelines for NMIs /DIs of COOMET that intend to achieve international recognition of their QMS through peer review from COOMET Technical Committee of Quality Forum (TC QF) on one hand and of COOMET QF itself, on another.

This document is developed by COOMET TC QF based on the assumption that 3 year transition period is worldwide accepted for both standards, which will be November 2019 for ISO 17034:2016 and respectively November 2020 for ISO/IEC 17025:2017.

This document will be applied to all NMIs /DIs of COOMET, which intend to achieve international recognition of their QMS through COOMET and request recognition of their Quality Management System (QMS) through the TC QF.

This policy applies to international editions of the above standards, not to publications adopted at the national level. Taking into account the fact that COOMET has two official languages, it is important to ensure the identity of the texts of standards for all NMI/DI within COOMET.


COOMET  NMIs /DIs are required to comply with the requirements of this document to maintain results of peer reviews from COOMET TC QF.  The responsibilities/obligation, actions and respective timelines for transition to ISO 17034:2016 and ISO/IEC 17025:2017 are provided below:
