33、uct faces during the pulling operation, divided by the cross-sectional area of the test specimen 4 Principle A test specimen is attached between two rigid plates or blocks, fastened in a tensile testing machine and pulled apart at a given speed. The maximum tensile force is recorded and the tensile

34、strength of the test specimen is calculated. 5 Apparatus 5.1 Tensile testing machine, appropriate for the 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 Rigid plates or blo

35、cks, with self-aligning attachment to avoid uneven distribution of tensile stress during the test. Examples of suitable arrangement to bond the test specimen are shown in Figure 1. 5.3 Adhesive, used to bond the test specimen between the rigid plates or blocks: The adhesive shall not reinforce or da

36、mage the surface layers of the product. Hot adhesives shall be avoided if they damage the product. Any solvent used shall be compatible with the product. Any test equipment which provides the same result with at least the same accuracy may be used. BS EN 1607:2013EN 1607:2013 (E) 6 6 Test specimens

37、6.1 Dimensions of test specimens The thickness of test specimens shall be equal to the original product thickness including any skins, facings and/or coatings. The test specimens shall be prisms of square cross section having sides of the following recommended dimensions: 50 mm 50 mm or 100 mm 100 m

38、m or 150 mm 150 mm or 200 mm 200 mm or 300 mm 300 mm. Dimensions used shall be as specified in the relevant product standard. In the absence of a product standard or any other European technical specification, the dimensions of test specimens may be agreed between parties. The linear dimensions shal

39、l be determined in accordance with EN 12085 to an accuracy of 0,5 %.

40、ecimen BS EN 1607:2013EN 1607:2013 (E) 8 6.2 Number of test specimens The number of test specimens shall be as specified in the relevant product standard. If the number is not specified, then at least five test specimens shall be used. In the absence of a product standard or any other European techn

41、ical specification, the number of test specimens may be agreed between parties. 6.3 Preparation of test specimens The test specimens shall be cut from the product so that the test specimen base is normal to the direction of the tensile force applied to the product in use. Test specimens shall be pre

42、pared by methods that do not change the original structure of the product. Any skins, facings and/or coatings shall be retained. The test specimens shall be representative of the product and preferably not taken closer than 15 mm from the edges of the product to avoid the influence of any handling d

43、amage. For products with non-plane or non-parallel faces, or which have skins, facings and/or coatings, preparation of test specimens shall be as specified in the relevant product standard. The tolerance on parallelism and flatness between the two faces of a test specimen shall be not more than 0,5

44、% of the test specimen side length, with a maximum of 0,5 mm. Before conditioning, the test specimens shall be attached to the two rigid plates or blocks using a suitable adhesive. 6.4 Conditioning of test specimens The test specimens (including the two rigid plates or blocks) shall be conditioned f

45、or at least 6 h at (23 5) C. In cases of dispute, they shall be conditioned at (23 2) C and (50 5) % relative humidity for the time specified in the relevant product standard. Other conditions may be used, provided that they give the same results. 7 Procedure 7.1 Test conditions Testing shall be car

46、ried out at (23 5) C. In cases of dispute, testing shall be carried out at (23 2) C and (50 5) % relative humidity. 7.2 Test procedure Determine the cross-sectional area of the test specimens in accordance with EN 12085. NOTE Carry out this determination preferably before the test specimen is attach

47、ed to the two rigid plates or blocks. Attach the test specimen in the tensile testing machine by means of the plate/block fixings and increase the tensile force with a constant speed of the crosshead (see 5.1) until failure occurs. Record the maximum force, in kN. Note the way in which the material

48、or the skin, facing and/ or coating failed. Discard any test specimen showing total or partial failure in the adhesive layer between the test specimen and the rigid plates or blocks.
