Interested parties are requested to review and submit comments on the 24 OIML Recommendations and Documents on legal measuring instruments that will be presented for ratification by the Conference. Comments may also be submitted on other issues relevant to the Conference.
The International Organization of Legal Metrology (OIML) is an intergovernmental treaty organization in which the United States and 56 other nations are members. Its principal purpose is to harmonize national laws and regulations pertaining to testing and verifying the performance of legal measuring instruments used for equity in commerce, for public and worker health and safety, and for monitoring and protecting the environment. The harmonized results promote the international trade of measuring instruments and products affected by measurement.
The U.S. Department of State has delegated technical participation in OIML to the National Institute of Standards and Technology. NIST coordinates participation of U.S. manufacturers, users of weighing and measuring instruments, legal metrology officials and other U.S. stakeholders in the technical work of OIML by circulating draft voluntary standards
All parties with an interest in the work of the OIML are requested to review and submit comments on any or all of the 24 Recommendations and Documents that will be presented for ratification by the Conference. All submitted comments will be reviewed and considered by NIST staff in the development of U.S. positions that will be put forward at the 14th Conference of OIML. Within two weeks of the comment submission deadline established in the
Each of the 24 Recommendations and Documents that will be presented for ratification by the Conference has already gone through a multi-year development and review-process involving technical experts and legal metrology experts from the United States and around the world. Ratification by the Conference is the final step in this process. The Recommendations and Documents have been divided into two categories—Category 1: those already approved by the International Committee of Legal Metrology (CIML) between 2009 and 2011, and Category 2: those that are expected to be submitted directly to the Conference for ratification. Because the Recommendations and Documents in Category 2 have not yet received CIML approval, comments received on these Recommendations and Documents are of additional importance to NIST staff. The 24 Recommendations and Documents and the OIML-member nations holding the secretariat responsible for their development are listed below:
• R14, “Polarimetric saccharimeters graduated in accordance with the ICUMSA International Sugar Scale” (Russian Federation);
• R35, “Material Measures of Length for General Use” (United Kingdom);
• R48, “Tungsten ribbon lamps for the calibration of radiation thermometers” (Russian Federation);
