ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to d

31、mination of the full thickness tensile strength in the longitudinal direction and the elongation at the reference force and breaking point of conveyor belts having a textile carcass. The method can also be used for the determination of full thickness tensile strength in the transverse direction and
32、the elongation at the breaking point, for use when the manufacturer is requested by the purchaser to state values for these properties.This International Standard is not suitable or valid for light conveyor belts as described in ISO 21183-1.2 Normative referencesThe following documents, in whole or

39、il rupture of the test piece occurs.5 Apparatus5.1 Tensile testing machine, of CRE or CRT type, calibrated to Grade 1 according to ISO 7500-1 and capable of extending the test piece at a constant rate, without interruption, of (100 10) mm/min.5.2 Device, such as an extensometer, with a measuring len
40、gth of at least 100 mm and accurate to within 0,1 mm or better, capable of measuring the elongation of the gauge length marked on the test piece. Use of a device that produces a graphical trace throughout the test is preferred.5.3 Grips, the form of which should prevent any slippage of the test piec
41、e during the tensile test. The use of grips with transverse serrations in accordance with Figure 1 is recommended.Dimensions in millimetres3050Figure 1 Grip with transverse serrations5.4 Die cutter or power saw, either of the dies with wall profiles as shown in Figure 2 being suitable for cutting th
42、e test pieces shown in Figure 3, Figure 4, and Figure 5. Other profiles may be used, but the critical feature is that the cut sides of the test piece are perpendicular to the test piece surfaces.DIN EN ISO 283:2016-04 EN ISO 283:2015 (E)6 6 Test pieces6.1 Shape and dimensionsThe shape and dimensions
43、 of the test piece shall be in accordance with Figure 3, Figure 4, Figure 5, or Figure 6.6.2 Method of selection of test piecesTest pieces shall be selected parallel, or at right angles, to the axis of the belt, and at not less than 50 mm from the edge of the belt. If test pieces are selected from a
44、 sample cut from the belt, no test piece shall be cut with its longitudinal edge less than 12 mm from the edge of the sample. In all cases, the cut or sawn sides of the test piece shall be perpendicular to its surface. No test piece shall contain a ply joint.For a test piece of type D, draw the form
45、 of the test piece on the surface of the belt or sample and from each edge of the sample, cut at five places with a power saw up to the drawn lines (see Figure 6).The type D test piece illustrated in Figure 6 should be limited to the testing of conveyor belts having tensile strengths greater than 2
