New York, Mar 19, 2014

The International Organization for Standardization (ISO) recently released a document focused on increasing public understanding of the Vienna Agreement, an accord between ISO and the European Committee for Standardization (CEN) that supports the increased alignment between European national standards and ISO International Standards. The Vienna Agreement, which replaced the 1989 Lisbon Agreement, was signed in 1991 and last revised in 2001.

The new document, “The Vienna Agreement – FAQs,” answers 21 frequently asked questions (FAQs) about the agreement, providing readers with insight into its history, goals, provisions, and effects. Among the questions answered by the document are:

  • How is information exchange at the committee level organized between ISO and CEN?
  • How is assignment of lead to the ISO or CEN committee determined?
  • Are ISO standards developed under the Vienna Agreement required to support European legislation?
  • Can publications other than standards be processed under the Vienna Agreement?
  • How can people in non-European ISO member countries get general information concerning the activities of CEN?

The full FAQ document is available online.
