The Joint BIPM, OIML, ILAC and ISO Declaration on Metrological Traceability was updated and re-signed on 13 November 2018 during the 26th meeting of the CGPM, held in Versailles.
The Joint Declaration available from here highlights the importance of metrological traceability and encourages the members of the four organizations – as well as others for whom metrological traceability is important – to adopt its recommendations. It is also referenced in the ISO/IEC 17025:2017 General requirements for the competence of testing.
This 2018 version was signed by Martin Milton (for the BIPM), Stephen Patoray (for OIML), Merih Malmqvist Nilsson (for ILAC), and Sergio Mujica (for ISO) and reaffirms the original Joint Declaration signed on 9 November 2011.
