It is identical with ISO 10456:1999. The UK participation in its preparation was entrusted by Technical Committee
5、B/540, Energy performance of materials, components and buildings, to Subcommittee B/540/1, European Standards for thermal insulation, which has the responsibility to: aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpretation
6、, or proposals for change, and keep the UK interests informed; monitor related international and European developments and promulgate them in the UK. A list of organizations represented on this subcommittee can be obtained on request to its secretary. Cross-references Attention is drawn to the fact
7、that CEN and CENELEC Standards normally include an annex which lists normative references to international publications with their corresponding European publications. The British Standards which implement these international or European publications may be found in the BSI Standards Catalogue under
8、 the section entitled International Standards Correspondence Index, or by using the Find facility of the BSI Standards Electronic Catalogue. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct applica
9、tion. Compliance with a British Standard does not of itself confer immunity from legal obligations.

16、 (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 which a technical committee has been established has the right to be represented on that committee. International organizations,
17、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 matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/
18、IEC Directives, Part 3. 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. International Standard ISO 10456 was prepared by
19、Technical Committee ISO/TC 163, Thermal insulation, Subcom- mittee SC 2, Calculation methods. This second edition cancels and replaces the first edition (ISO 10456:1997), of which it constitutes a minor revision.

21、es 1 Scope This International Standard specifies methods for the determination of declared and design thermal values for thermally 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
22、. These procedures are valid for design ambient temperatures between 30 C and +60 C. Conversion coefficients for temperature, 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 a
23、geing or other effects like convection or settlement. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these
24、 publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred
25、 to applies. Members of ISO and IEC maintain registers of currently valid International Standards.

32、sured values from the following methods, or equivalent national methods, shall be used: guarded hot plate in accordance with ISO 8302; heat flow meter in accordance with ISO 8301; hot box in accordance with ISO 8990. To avoid conversions, it is recommended that measurements be conducted under condit
33、ions corresponding to the selected set of conditions given in Table 2. The mean test temperature should be chosen so that the application of the temperature coefficients does not introduce a change of more than 2 % from the measured value. The following testing conditions are required: measured thic

The declared value shall be determined either at a thickness large enough to
37、 neglect the thickness effect, or the declared values for smaller thicknesses shall be based on measurements at those thicknesses. The data used shall be either directly measured values according to the test methods given in clause 4, or obtained indirectly by making use of an established correlatio
38、n with a related property such as density. When all data have not been measured under the same set of conditions, they shall first be brought to one set of conditions (see clause 7). Then a statistical single value estimate shall be calculated. Annex C refers to International Standards on statistics
39、 that may be used. During calculations no value shall be rounded to less than three significant figures. The declared value is the estimated value of the statistical single value, rounded according to the following rules: a) for thermal conductivity given in watts per metre kelvin W/(m K): 100 0,032
