6. OIML Statement (47th CIML, Resolution 23)
The OIML supports the CGPM's intention to revise the SI in order that it will continue to meet the needs of science, technology, and commerce in the 21st century. From the inquiry amongst the OIML Technical Committees TC 2, TC 9, TC 9/SC 3 and TC 11, and the CIML Members, it is concluded that the new SI definitions are considered to have little to no impact on routine measurements of time, length, luminous intensity, electric current, temperature, amount of substance, and related derived SI quantities. A potential impact may be on accurate mass measurements using weights of classes E1 and E2 according to OIML R111.
Update on the new SI

7. OIML Statement (47th CIML, Resolution 23)
Only careful adherence to the 2010 (and 2013) recommendations of the CCM will preserve the continuity, accuracy and traceability of future mass measurements.
The OIML supports the intention of the CGPM to further improve formulations for the definitions of the SI base units so that the new SI remains understandable to all those who need it.

13. Conclusion
The OIML statement and the CECIP position were well recognized by the following important committees:
Consultative Committee for Mass and related quantities
Consultative Committee for Units
International Committee for Weight and Measures
And explicitely mentionned in the CCM recommendation G1 (2013)
These statements positively influenced and supported the establishment of a realistic roadmap to the new SI.
