8、oreword 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 which a te
9、chnical 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 matters
10、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 circulated
11、 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 responsible f

ISO 29465 was prepared by Technical Committee ISO/TC 163, Thermal performance and energy use in the built environment, Subcommittee SC 1, Test and measurement methods.

24、ecifies the equipment and procedures for determining the length and width of full-size products. It is applicable to thermal insulating products. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 length l longer linear dimension of the major su
25、rface of the test specimen 2.2 width b shorter linear dimension of the major surface of the test specimen, measured at right angles to the length 3 Principle A specimen is placed on a flat surface and direct linear measurement is made with a metal rule or a metal tape. 4 Apparatus 4.1 Flat surface.
26、4.2 Metal rule or metal tape, graduated in millimetres and permitting reading to an accuracy of 0,5 mm. Any test equipment that provides the same result with at least the same accuracy may be used. 5 Test specimens 5.1 Dimensions of test specimens The test specimen shall be the full-size product. 5.
27、2 Number of test specimens The number of test specimens shall be as specified in the relevant product standard. In the absence of a product standard, the number of test specimens may be agreed between parties. ISO 29465:2008(E) 2 ISO 2008 All rights reserved5.3 Conditioning of test specimens The tes
28、t specimens shall be stored for at least 6 h at (23 5) C. In cases of dispute, they shall be stored at (23 2) C and (50 5) % relative humidity for the time specified in the relevant product standard. In tropical countries, different conditioning and testing conditions can be relevant. In this case,
29、the conditions shall be 27 C and 65 % RH, and be stated clearly in the test report. 6 Procedure 6.1 Test conditions The test shall be carried out at (23 5) C. In case of dispute, it shall be carried out at (23 2) C and (50 5) % relative humidity. In tropical countries, different conditioning and tes
30、ting conditions can be relevant. In this case, the conditions shall be 27 C and 65 % RH, and be stated clearly in the test report. 6.2 Test procedure Lay the test specimen carefully on a flat surface. For test specimens with both dimensions less than or equal to 1,5 m, take one measurement of length
31、, l, and one measurement of width, b, at the positions shown in Figure 1. For test specimens greater than 1,5 m long, make one additional width measurement for each extra metre of length, up to a maximum of five measurements, with the measurements equally spaced as shown in Figure 2. In this case, b
32、 is the mean value of all measured values of the width. For test specimens greater than 1,5 m wide, make one additional length measurement for each extra 1 m of width, with the measurements equally spaced. All lengths and widths shall be read to the nearest millimetre. Figure 1 Positions for measuri

34、 of results The length and width shall be expressed in millimetres, to the nearest millimetre, as the mean value for each specimen. For products 3 m long or greater, the mean length value shall be reported to the nearest 5 mm. 8 Accuracy of measurement NOTE It has not been possible to include a stat
35、ement of the accuracy of the method in this edition of this International Standard, but it is intended to include such a statement when this International Standard is next revised. 9 Test report The test report shall include the following information: a) reference to this International Standard; b)
36、product identification: 1) product name, factory, manufacturer or supplier, 2) production code number, 3) type of product, 4) packaging, 5) form in which the product arrived at the laboratory, 6) other information as appropriate, e.g. nominal thickness, nominal density; ISO 29465:2008(E) 4 ISO 2008
