31、 EN 824:2013-05 EN 824:2013 (E) 5 1 Scope This European Standard specifies the equipment and procedure 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 product

32、s with straight edges. For products of other shape, e.g. profiled edges, the method can be adapted accordingly. 2 Normative references This European Standard contains no normative references. 3 Terms and definitions For the purposes of this document, the following term and definition applies. 3.1 de

33、viation from squareness distance from one limb of a perfect square to the edge of the product at a given distance from a corner Note 1 to entry: See Figures 1 to 3. 4 Principle Apply a metal square to the product edges and measure the deviation between one limb of the metal square and the products e

34、dge (see Figure 1). 5 Apparatus 5.1 Flat surface. 5.2 Metal rule or metal tape, graduated in millimetres and permitting reading to 0,5 mm; 5.3 Metal square, with limbs at least 500 mm long with a deviation from squareness of not more than 0,1 mm when measured at 500 mm from the corner. Any test equi

35、pment which provides the same result with at least the same accuracy may be used. 6 Test specimens 6.1 Dimensions of test specimens The test specimens shall be the full-size product. 6.2 Number of test specimens The number of test specimens shall be as specified in the relevant product standard. In

36、the absence of a product standard, the number of test specimens may be agreed between parties. 6.3 Conditioning of test specimens The test specimens should be stored for a least 6 h at (23 5) C. In case of dispute they shall be stored at (23 2) C and (50 5) % relative humidity for the time specified

37、 in the relevant product standard.

In case of dispute it shall be carried out at (23 2) C and (50 5) % relative humidit

38、y. 7.1.2 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 sides of the test specimen with the right angle of the square aligned against the adjoining edge as in Figure 2; b) mea

39、sure the distance abbetween 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 test specimens with a side of less than 500 mm, c is the maximum width or length of the specimen; 2) for the test specimen with a side

40、 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 corner of the test specimen having angles smaller 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 re

41、ported as the maximum deviation from linearity amax. expressed in millimetres (see Figure 4). 7.2 Determination of the squareness of the thickness edge 7.2.1 Test conditions The test should be carried out at (23 5) C. In case of dispute it shall be carried out at (23 2) C and (50 5) % relative humid

42、ity. 7.2.2 Test procedure Lay the test specimen on a flat surface and measure the deviation from squareness of the thickness as follows: a) place the metal square on the flat surface against one edge of the test specimen as in Figure 3; b) measure the distance adto the nearest 0,5 mm between the edg

43、e of the test specimen and the edge of the square at the point of the greatest deviation along the side; c) repeat for all sides; d) turn the test specimen over and repeat items a) to c); e) report the largest figure as the deviation from squareness of the thickness edge.
