9、d iii 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 normally carried out through ISO technical committees. Each member body interested in a subject for whi
10、ch 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 the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all m
11、atters 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 prepare International Standards. Draft International Standards adopted by the technical committees are cir
12、culated 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 some of the elements of this document may be the subject of patent rights. ISO shall not be held respon
13、sible for identifying any or all such patent rights. ISO 15758 was prepared by the European Committee for Standardization (CEN) (as EN 14114:2002) and was adopted, under a special “fast-track procedure”, by Technical Committee ISO/TC 163, Thermal performance and energy use in the built environment,

18、 of buildings and building components“, the secretariat of which is held by SIS. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by September 2002, and conflicting national standards shall be withdra
19、wn at the latest by September 2002. The enquiry version was designated prEN ISO 15758. However, as a result of the enquiry, ISO decided to decouple from the Vienna Agreement; CEN and ISO will proceed to publication on their own. This standard is one of a series of standards which specify calculation
20、 methods for the design and evaluation of the thermal and moisture related performance properties of buildings and building components. The Annexes A and B are informative. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to
21、 implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.
