On July 9, 2010, the American National Standards Institute (ANSI) will host a webinar to discuss draft international guidance on the labeling of manufactured nano-objects and products containing manufactured nano-objects. The European Committee for Standardization (CEN) Technical Committee (TC) 352 Nanotechnologies and the International Organization for Standardization (ISO) TC 229 Nanotechnologies are jointly developing a Technical Specification entitled “Guidance on the labeling of manufactured nano-objects and products containing manufactured nano-objects,” under the guidelines of the Vienna Agreement. CEN holds the leadership of this Technical Specification development activity. CEN and ISO/TC 229 were expected to distribute the draft Technical Specification June 18, 2010. Because ANSI expects the document to have broad implications for a number of U.S. industry sectors, including food safety/industry, cosmetics, and chemicals, the ANSI-Accredited U.S. Technical Advisory Group (TAG) to ISO TC 229 Nanotechnologies will host the webinar to review this document and solicit input from potentially affected U.S. stakeholders. The webinar will include an overview of the current draft of this proposed CEN/ISO Technical Specification (including background information to its development) and provide participants with the opportunity to ask questions and provide comments. These comments will be provided to the ANSI-Accredited U.S. TAG for consideration in connection with the development of the U.S. position and vote on this draft document. The webinar is free, but registration is required.
