18、technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matter

24、All rights reservedBS EN ISO 3037:2013ISO 3037:2013(E)IntroductionA variety of methods for the determination of edgewise crush resistance are in use in different parts of the world. These can be classified into three groups as follows:a) Those in which a carefully cut rectangular test piece is teste

25、d without any special treatment or modification (e.g. ISO 3037).b) Those in which the edges of the test piece to which the force is applied are waxed, to prevent the test result being influenced by “edge effects“ (e.g. ISO 13821, Corrugated fibreboard Determination of edgewise crush resistance Waxed

26、 edge method).c) Those in which the test piece edges are not waxed but the shape of the test piece is such that the length is substantially reduced at a point midway between the loaded edges, in order to induce the failure to occur away from those edges (e.g. JIS Z 0403-2).The dimensions of the test

27、 piece vary from one group to the other and, in group c), the methods vary in the shape and method of reducing the length, and in whether or not the test piece is held in a clamp during crushing.The methods may not give the same numerical results, but it can be shown that most of them can be used to

28、 predict the top-to-bottom compression strength which will be achieved when the board is properly converted into a transport package.This International Standard describes a method from group a). It is intended as a method for quality measurement and quality specification purposes and is selected bec

29、ause it correlates with the top-to-bottom compression strength of the final transport package and because it is the simplest and most operationally convenient method, an important factor when large numbers of tests need to be conducted. However, it does not measure the actual intrinsic compressive s

30、trength of the corrugated fibreboard, giving lower results than most of the methods in groups b) and c). This systematic difference is due to edge effects.Other methods may be used for other purposes, particularly when the object of the test is to study fundamental structural characteristics of the

31、package.There are methods available for calculating the edgewise crush resistance from the compression strength of the component papers.

35、 crush resistancemaximum force per unit length that a test piece of corrugated fibreboard can support until the onset of failure when a compressive force is applied with the flute structure perpendicular to the loading surfaces4 PrincipleA rectangular test piece of corrugated fibreboard, placed betw

36、een the platens of a compression tester with the flutes perpendicular to the surfaces of the platens, is subjected to an increasing compressive force until failure occurs. The maximum force sustained by the test piece is measured.5 Apparatus5.1 Fixed-platen compression testing machine as described i

37、n ISO 13820. It is preferable to avoid the use of emery paper on the platens.While it is safer to avoid the use of emery paper on the platens, because it is a requirement of other test methods, the platens may be faced with very fine emery paper of a grade not coarser than 00. Where this is done, du

38、e regard should be paid to maintaining the flatness and parallelism requirements specified for the faces.NOTE A flexible beam compression tester per ISO 13820 is not recommended for this test method as there are significant questions regarding its ability to be maintained with sufficient parallelism

40、 described in 8.3 and 8.4.5.3 Guide blocks, two rectangular, smooth-finished, blocks of dimensions approximately 20 mm x 20 mm x 100 mm, to support the test piece and keep it perpendicular to the platen surfaces. It is advisable to fit each guide block with a probe, to enable each block to be moved

41、safely during the test.6 SamplingIf the average quality of a lot of corrugated fibreboard is to be determined, sampling shall be carried out in accordance with ISO 186. If another type of sample is to be tested, make sure that the test pieces taken are representative of the sample received.7 Conditi

42、oningThe sample shall be conditioned in accordance with ISO 187.8 Preparation of test pieces8.1 Prepare the test pieces in the same atmospheric conditions as used to condition the sample.8.2 Using a sharp blade and a procedure that ensures the cuts are parallel, cut, from the sample, specimens with

43、the following dimensions: 100,0 mm 0,5 mm in the direction perpendicular to the flutes and 70 mm to 300 mm in the direction parallel to the flutes, such that test pieces can be obtained from an undamaged area of the sample.8.3 From undamaged areas of the specimens (8.2), using an appropriate cutting

44、 device (5.2), cut sufficient test pieces 25,0 mm 0,5 mm in the direction parallel to the flutes, so that 10 valid tests are obtained. Each test piece will then measure 25,0 mm 0,5 mm in height (the direction of the flutes) and 100,0 mm 0,5 mm in length (the direction perpendicular to the flutes).If

45、 a Billerud-type cutter (5.2) is used, insert the uncut strip until it almost contacts the end stop, and ensure that a sufficient length of strip extends on the other side of the blades and that the edge is in contact with the squareness guide.Irrespective of the method of cutting, the edges subject

46、ed to load shall be cleanly cut, straight, parallel and perpendicular to the board surfaces (8.4).8.4 Test piece quality. Each test piece shall be examined for quality.The width of the test piece shall not vary by more than 0,1 mm along its length.Cleanness of cut is judged by inspection of the test

47、 pieces. Flutes shall show no discernible distortion, and the cut edges shall not be furry or have loose fibres visible when inspected under normal laboratory conditions, i.e. under room lighting with no magnification.Straightness, parallelism and perpendicularity may be judged by the following proc

48、edure.Stand two test pieces on their cut edges on a plane surface with two of their faces almost touching. With perfectly flat board, the two adjacent faces should appear flat and parallel to each other over their whole surface. If the board is warped, this may not be so, but the test pieces are acc

49、eptable if they stand vertically on their bottom edges, if the top cut surfaces appear flat and parallel to each other and at right angles to the liner surfaces close to the cut, and if the cut ends of the test pieces appear to be in the same plane. It should not be possible to see light under the cut edge of either test piece, when a load of about 1 N (equivalent to light finger pressure) is applied to the top edge.2 ISO 2013 All rights reservedBS EN ISO 3037:2013ISO 3037:2013(E)Rotate one test piece end-for-end (rotate 180 about its ve
