11、 or networking permitted without license from IHS -,-,- ISO 16818:2008(E) iv ISO 2008 All rights reserved Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is nor
12、mally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in
13、the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepar
14、e 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. Attention is drawn to the possibility that som
15、e of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

NOTE 2 In some cases, the designer can determine the location of the exterior building envelope by the location that they place the insulation. For instance, it is not uncommon for a stairwell to be at the outside edge of the building. If tha
