It is applicable to thermal insulating products. This European Standard can be used to determine whether the product has sufficient str
34、ength to withstand stresses during transportation and application. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references,

37、method 3 Terms and definitions For the purposes of this document, the following term and definition applies. 3.1 tensile strength parallel to faces t maximum recorded tensile force parallel to the product faces during the pulling operation, divided by the cross-sectional testing area of the test spe
38、cimen 4 Principle A test specimen is attached to two clamps which are fastened in a tensile testing machine and pulled apart at a given speed. The maximum tensile force is recorded and the tensile strength of the test specimen is calculated. 5 Apparatus 5.1 Tensile testing machine, appropriate for t
39、he range of force and displacement involved, capable of having a constant crosshead speed adjusted to (10 1) mm/min and capable of measuring the force to an accuracy of 1 %. 5.2 Two clamps, designed so as to avoid failure of the test specimen in the area of the clamps. The clamps shall be positioned
40、 so that the tensile stress is uniformly distributed during the test. DIN EN 1608:2013-05 EN 1608:2013 (E) 6 An example of suitable equipment is shown in Figure 1. Any test equipment or method which provides the same result with at least the same accuracy may be used. 6 Test specimens 6.1 Dimensions
41、 of test specimens The thickness of the test specimens shall be the original product thickness including any skins, facings, and/or coatings. The test specimens shall be cut with the shape and with the dimensions shown in Figure 2. For small products or because of equipment limitations, the test spe
42、cimen length and width shall be adjusted proportionally, but with a minimum length of 500 mm. Other specimen shapes which provide the same result to at least the same accuracy may be used. 6.2 Number of test specimens The number of test specimens shall be as specified in the relevant product standar
43、d. If the number is not specified, then at least three test specimens shall be used. In the absence of a product standard or any other European Technical Specification, the number of test specimens may be agreed between parties. Figure 1 Example of suitable clamps 6.3 Preparation of test specimens T
44、he test specimens shall be cut from the full size product so that the length direction corresponds to the direction in which the tensile force is applied to the product in its application. DIN EN 1608:2013-05 EN 1608:2013 (E) 7 Test specimens shall be prepared by methods that do not change the origi
45、nal structure of the product. Special methods of preparation, when needed, are given in the relevant product standard or any other European Technical Specification. 6.4 Conditioning of test specimens The test specimens shall be conditioned for at least 6 h at (23 5) C. In case of dispute, they shall
46、 be conditioned at (23 2) C and (50 5) % relative humidity for the time stated in the relevant product standard. 7 Procedure 7.1 Test conditions Testing 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. 7.2 Test procedure Measur
47、e the thickness of the testing area, d, to the nearest millimetre, in accordance with EN 823. Measure the length of the test specimen, l, and the width of the testing area, b, to the nearest millimetre, in accordance with EN 12085. Attach the test specimen centrally between two clamps to distribute
48、the stress uniformly. Place it carefully in the tensile testing machine and increase the tensile force with a constant speed of the crosshead (see 5.1) until failure occurs. Record the maximum tensile force, in kilonewtons. Note the way in which the product failed. Discard any test specimens that fa
49、iled outside the testing area (see Figure 2).
