The work of preparing International Standards is normally
8、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 the wo
9、rk. 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 3. Draft International Standards adopted by the technical c
10、ommittees 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. International Standard ISO 10456 was prepared by Technical Committee ISO/TC 163, Thermal insulation, Subcom- mittee SC 2, Calcula

14、rmally homogeneous building materials and products. It also gives procedures to convert values obtained under one set of conditions to those valid for another set of conditions. These procedures are valid for design ambient temperatures between 30 C and +60 C. Conversion coefficients for temperature
15、, valid for mean temperatures between 0 C and 30 C, and moisture are given in annex A. This International Standard does not give any conversion coefficients for the effect of ageing or other effects like convection or settlement. 2 Normative references The following normative documents contain provi
16、sions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigat
