The work of preparing Int
9、ernational 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, governmental and non-governmental, in liaison w
10、ith 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/IEC Directives, Part 2. The main task of techni
11、cal committees is to prepare 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
12、to the possibility that some 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.

It is applicable to thermal insulating products. 2 Terms and definitions For the pu
25、rposes of this document, the following term and definition apply. 2.1 thickness d linear dimension measured perpendicularly to the length and width plane 3 Principle The distance is measured between a hard, flat reference surface on which the test specimen rests and a pressure plate resting freely o
26、n the top face of the specimen. 4 Apparatus 4.1 Measuring device, comprised of a) a dial gauge, capable of measuring to an accuracy of at least 0,5 mm and mounted on a rigid frame fastened to a flat rigid base plate that is at least as large as the test specimen; and b) a square pressure plate, 200
27、mm square, which exerts a total pressure on the test specimen of either (50 1,5) Pa or (250 5) Pa (including the force exerted by the dial gauge). NOTE If a higher accuracy is required, it is specified in the relevant product standard or agreed between parties. An example of a suitable apparatus is
28、given in Figure 1. The pressure shall be as given in the relevant product standard. Any test equipment that provides the same result with at least the same accuracy may be used.

29、lat rigid baseplate Figure 1 Example of an apparatus suitable for determining the thickness 5 Test specimens 5.1 Dimensions of test specimens The test specimen shall be the full-size product, but it can be necessary to cut the product into pieces of appropriate size. 5.2 Number of test specimens The
30、 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 upon. 5.3 Conditioning of test specimens The test specimens shall be stored for at least 6 h at (23 5) C. In cases of dispute, they shall
31、 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, the conditions shall be 27 C and 65 % RH and be stated clearly in the test report. 5.4 Pr
32、eparation of test specimens Any facings or coatings shall be retained. For compressed products, the preparation of test specimens shall be in accordance with Annex A. ISO 29466:2008(E) ISO 2008 All rights reserved 3 6 Procedure 6.1 Test conditions The test shall be carried out at (23 5) C. In case o
33、f dispute, it shall be carried out at (23 2) C and (50 5) % relative humidity. In tropical countries, different conditioning and testing 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 specim
34、en carefully on the baseplate, ensuring that the measuring area is in contact with the baseplate. Test specimens faced or coated on one side shall be placed with the facing or coating against the baseplate. Place the pressure plate on the specimen, exerting a total pressure of either (50 1,5) Pa or
35、(250 5) Pa at a designated position with the dial gauge centrally located. Take two measurements for test specimens of lengths less than or equal to 600 mm, four measurements for test specimens greater than 600 mm and less than or equal to 1 500 mm in length, and one additional measurement for each
36、additional 500 mm exceeding 1 500 mm in length. Take the measurements d 1 , d 2 , . and d nat positions on the surface, as shown in Figure 2. Measure to an accuracy in accordance with 4.1.

37、 Calculation and expression of results The thickness of the test specimen shall be expressed in millimetres, to the nearest millimetre, as the mean value of the measurements made at all the points for the test specimen (see Figure 2). NOTE If a higher accuracy is required, it is specified in the rel
38、evant product standard or agreed between parties. ISO 29466:2008(E) ISO 2008 All rights reserved 5 8 Accuracy of measurement NOTE It has not been possible to include a statement of the accuracy of the method in this edition of this International Standard, but it is intended to include such a stateme
