8、ional 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 technical committee has bee

9、n 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 of electrotechnical stand

10、ardization. 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 to the member bodies for

11、 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 for identifying any or all

24、dure for determining the deviation from squareness for length, width and/or thickness of full-size products. It is applicable to thermal insulating products. The method is normally applicable to products with straight edges. For products of other shape, e.g. profiled edges, the method can be adapted

25、 accordingly. 2 Terms and definitions For the purposes of this document, the following term and definition apply. 2.1 deviation from squareness distance from one limb of a perfect square (see Figures 1, 2 and 3) to the edge of the product at a given distance from a corner Figure 1 Example of the mea

30、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. 5.3 Conditioning of test specimens The test specimens should be stored for at least 6 h at (23 5) C. In case of dispu

31、te, 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, the conditions shall be 27 C and 65 % RH and be stated clearly in the test

In this case, the conditions shall be 27 C and 65 % RH and be stated clearly in the test report. 6.1.2 Test procedure Lay the test specimen on a flat surface and measure the deviation from squareness of length and width as follows. a) Place the metal square along one of the

34、 sides of the test specimen with the right angle of the square aligned against the adjoining edge as shown in Figure 2. b) Measure the distance, a b , between the edge of the test specimen and the edge of the metal square, at a distance, c, from the corner, to the nearest 0,5 mm, where 1) for the te

35、st specimens with a side of less than 500 mm, c is the maximum width or length of the specimen, 2) for the test specimens with a side equal to or greater than 500 mm, c is the length of the inner side of the square (see Figure 2). c) Repeat for all corners of the test specimen having angles smaller

36、than or equal to 90. d) If there is any significant deviation from linearity of the edges in the length or the width, this shall be reported as the maximum deviation from linearity, a max , expressed in millimetres (see Figure 4).
