As at national level, international standards work begins with a "new work item proposal". A simple majority of national standards organizations with an interest in the subject matter is required for the proposal to be approved. In addition, a sufficient number of these must also agree to participate in the work. Within two months a "committee draft" is circulated among the members of the responsible Technical Committee for voting. A draft is drawn up taking any comments received into consideration.

The draft standard is then made available to all ISO or IEC members, who have three months to submit their national position and comments. Within a two-month period, anyone may comment on this draft for example via DIN's German-language draft standards online portal. The national mirror committee discusses all comments received and submits the consolidated national viewpoint to ISO. If the criteria for approval are fulfilled during the voting procedure, the draft is then published as an International Standard.

If they are not fulfilled, or if the responsible working group so decides, a Final Draft is published. No comments are submitted during this voting period. Acceptance of the Final Draft requires a two-thirds majority of all active members participating, and not more than a quarter of all votes may be negative. Ratification of an International Standard takes place following positive voting.

In addition, a standard that has been developed at European level can be simultaneously adopted as an International Standard by means of parallel voting procedures in accordance with the Vienna Agreement. Such standards are to be automatically adopted by the national standards organizations. DIN's Statutes lay down the principles and goals of German standardization. The German Standardization Strategy sets out the goals of German industry, politics, research and standardization.

Standardization is a key strategic instrument for companies of all sizes. Standardization is a transparent process - that anyone can take part in! Standards and other technical rules from Germany and around the world can be purchased from Beuth Verlag, DIN's publishing house. Required Functional Personalization Show details.
