🚀 𝗡𝗲𝘄 𝗢𝗜𝗠𝗟 𝗽𝘂𝗯𝗹𝗶𝗰𝗮𝘁𝗶𝗼𝗻 𝗿𝗲𝗹𝗲𝗮𝘀𝗲𝗱!

𝗢𝗜𝗠𝗟 𝗗 𝟭𝟭:𝟮𝟬𝟮𝟲 𝘎𝘦𝘯𝘦𝘳𝘢𝘭 𝘳𝘦𝘲𝘶𝘪𝘳𝘦𝘮𝘦𝘯𝘵𝘴 𝘧𝘰𝘳 𝘮𝘦𝘢𝘴𝘶𝘳𝘪𝘯𝘨 𝘪𝘯𝘴𝘵𝘳𝘶𝘮𝘦𝘯𝘵𝘴 – 𝘌𝘯𝘷𝘪𝘳𝘰𝘯𝘮𝘦𝘯𝘵𝘢𝘭 𝘤𝘰𝘯𝘥𝘪𝘵𝘪𝘰𝘯𝘴 is now available:
https://www.oiml.org/en/publications/documents

This new edition supersedes D 11:2013, and has been approved by the CIML using the 𝗗𝗶𝗿𝗲𝗰𝘁 𝗢𝗻𝗹𝗶𝗻𝗲 𝗔𝗽𝗽𝗿𝗼𝘃𝗮𝗹 procedure – a faster alternative to the traditional multi-step approval process (Preliminary Online Ballot followed by formal voting at the CIML meeting).

This is only the second time the fast-track mechanism has been used in recent years, and successfully demonstrates its value in enabling timely updates to widely used OIML documents.

OIML D 11 is a cornerstone document in legal metrology, widely referenced for assessing the influence of environmental conditions on measuring instruments. The 2026 revision ensures continued alignment with current technologies and practices, supporting the reliability and performance of measuring instruments worldwide.

Our sincere thanks go to all the experts, Technical Committee members, and CIML members who contributed to this revision.
