Foreword3DIN EN ISO 3037:2013-12EN ISO 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 c
24、arefully cut rectangular test piece is tested 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 Dete
25、rmination of edgewise crush resistance Waxed 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
26、.g. JIS Z 0403-2).The dimensions of the test 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 c
27、an be shown that most of them can be used to 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 qualit
28、y specification purposes and is selected because 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 no
29、t measure the actual intrinsic compressive strength 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 fu
30、ndamental structural characteristics of the package.There are methods available for calculating the edgewise crush resistance from the compression strength of the component papers.4DIN EN ISO 3037:2013-12EN ISO 3037:2013 (E) 1 ScopeThis International Standard specifies an unwaxed edge method for the
31、 determination of the edgewise crush resistance of corrugated fibreboard. It is applicable to all corrugated fibreboard grades.2 Normative referencesThe following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For un
32、dated references, the latest edition of the referenced document (including any amendments) applies.ISO 186, Paper and board Sampling to determine average qualityISO 187, Paper, board and pulps Standard atmosphere for conditioning and testing and procedure for monitoring the atmosphere and conditioni
33、ng of samplesISO 13820, Paper, board and corrugated fibreboard Description and calibration of compression-testing equipment3 Terms and definitionsFor the purposes of this document, the following terms and definitions apply.3.1edgewise crush resistancemaximum force per unit length that a test piece o
34、f 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 between the platens of a compression tester with the flutes perpendicu
35、lar 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 in ISO 13820. It is preferable to avoid the use of emery paper on t
36、he 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, due regard should be paid to maintaining the flatness and parallelis
37、m 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 to provide accurate test values for these specimens.5DIN EN ISO 3
38、037:2013-12EN ISO 3037:2013 (E)5.2 Cutting device, such as a high-speed table saw or Billerud-type cutter (see Annex A), capable of cutting test pieces to the quality of cut described in 8.3 and 8.4.5.3 Guide blocks, two rectangular, smooth-finished, blocks of dimensions approximately 20 mm x 20 mm
39、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 safely during the test.6 SamplingIf the average quality of a lot of corrugated fibreboard is to be determined, sampling shall b
40、e 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 ConditioningThe sample shall be conditioned in accordance with ISO 187.8 Preparation of test pieces8.1 Prepare the test pieces in the
41、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 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 par
42、allel 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 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 ob
43、tained. 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 a Billerud-type cutter (5.2) is used, insert the uncut strip until it almost contacts the end stop, and ensure that a sufficie
44、nt 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 subjected to load shall be cleanly cut, straight, parallel and perpendicular to the board surfaces (8.4).8.4 Test piece quality. Each
45、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 pieces. Flutes shall show no discernible distortion, and the cut edges shall not be furry or have loose fibres visible when in
46、spected under normal laboratory conditions, i.e. under room lighting with no magnification.Straightness, parallelism and perpendicularity may be judged by the following procedure.Stand two test pieces on their cut edges on a plane surface with two of their faces almost touching. With perfectly flat
47、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 acceptable if they stand vertically on their bottom edges, if the top cut surfaces appear flat and parallel to each other and at r
48、ight 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.6DIN EN
49、 ISO 3037:2013-12EN ISO 3037:2013 (E) Rotate one test piece end-for-end (rotate 180 about its vertical axis) and invert it (rotate 180 about its horizontal axis), then invert the other test piece. In each configuration, the criteria of the preceding paragraph shall apply.Test other pairs of test pieces in the same way.With cutters of the high-speed saw and Billerud type (Annex A) and any other type of cutter, where relevant, these checks should be done when t
