EN 825:2013 (E) DIN EN 825:2013-055 1 Scope This European Standar
29、d specifies the equipment and procedures for determining the deviation from flatness for full-size products. It is applicable to thermal insulating products. 2 Normative references This European Standard contains no normative references. 3 Terms and definitions For the purposes of this document, the
30、 following term and definition applies. 3.1 deviation from flatness maximum distance between the product placed on a flat surface with the convex side uppermost and the flat surface 4 Principle The maximum distance between the product placed on a flat surface and the flat surface is measured. 5 Appa
31、ratus 5.1 Flat surface. 5.2 Metal rule or metal tape, graduated in millimetres and permitting reading to 0,5 mm. 5.3 Rigid frame with a movable measuring device consisting of a disc with a diameter of 30 mm, fixed to a graduated pin or a dial gauge (graduated to at least 0,5 mm) applying a load of (
32、2,0 0,1) N. Any test equipment 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 specimen shall be the full-size product. 6.2 Number of test specimens The number of test specimens shall be as specified in the releva
33、nt product standard. In 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 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 humid
34、ity for the time specified in the relevant product standard. EN 825:2013 (E) DIN EN 825:2013-056 7 Procedure 7.1 Test conditions The test shall be carried out at (23 5) C. In cases of dispute, it shall be carried out at (23 2) C and (50 5) % relative humidity. 7.2 Test procedure 7.2.1 Lay the test s
35、pecimen with the convex face, if any, uppermost on a flat surface. If there is a visible deviation from flatness only along the length or only along the width, make the measurement in accordance with 7.2.2 (see Figures 1a and 1b). If there is a deviation from flatness along both the length and width
36、 (warped products), make the measurement in accordance with 7.2.3 (see Figure 2). 7.2.2 Using the metal tape or rule, measure the maximum distance between the bottom edge of the specimen and the flat surface, Smax, to the nearest 0,5 mm. 7.2.3 Locate the maximum and minimum distances from the flat s
37、urface using the measuring device (see 5.3) as shown in Figure 2. At these positions read the distances Ymaxand Ymin,to the nearest 0,5 mm. If the test specimen only rests on three points, the possibility of alternative flatness measurements exists and all shall be measured. a) Measurement of deviat
38、ion from flatness in length b) Measurement of deviation from flatness in width Figure 1 Measurement of deviation from flatness EN 825:2013 (E) DIN EN 825:2013-057 Figure 2 Location of maximum and minimum distances 8 Calculation and expression of results For test specimens with deviation from flatnes
39、s in one direction only, report the deviation as the maximum value measured in millimetres. For warped products, calculate the deviation from flatness, Smax, in millimetres, using the following formula: Smax= Ymax Ymin (1) 9 Accuracy of measurement NOTE It has not been possible to include a statemen
40、t of the accuracy of the method in this edition of the standard, but it is intended to include such a statement when the standard is next revised. 10 Test report The test report shall include the following information: a) reference to this European Standard; b) product identification: 1) product nam
41、e, factory, manufacturer or supplier; 2) production code number; 3) type of product; 4) packaging; 5) the form in which the product arrived at the laboratory; 6) other information as appropriate, e.g. nominal thickness, nominal density; EN 825:2013 (E) DIN EN 825:2013-058 2) conditioning; 3) deviati
42、on from Clauses 6 and 7, if any; 4) date of test; 5) general information relating to the test; 6) any occurrences which may have affected the results. Information about the apparatus and identity of the technician should be available in the laboratory but it need not be recorded in the report; d) results: all individual values and the maximum value of the deviation from flatness and the position where it occurred. c) test procedure: 1) pre-test history and sampling (e.g. who sampled and place of sampling ); EN 825:2013 (E) DIN EN 825:2013-05
