Each member body interested in a subject for which a technical committee has been International Standards are drafted in accordance with the rules given in the ISO/lEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

ISO 12579 was prepared by Technical Committee ISO/TC 165, Timber structures. ional Organization for Standardization @ISo2007-Allrightsreserved ISO 12579:2007(E) Introduction This International Standard was developed by TC 165 5 as a production quality-control test to be used for structural glulam. It is meant to be used in conjunction with IsO 12578 and to be applied to each production batch. The frequency of testing and the pass/fail criteria are detailed in ISO 12578. There is nothing, in principle, that would prevent the test method from being applied to non-structural glulam.
