8、rt of BS 4826 has been prepared under the direction of the Packaging and Freight Containers Standards Committee. It is identical with ISO8768:1986 “Packaging Complete, filled transport packages Toppling test” published by the International Organization for Standardization (ISO). In 1992 the European

9、 Committee for Standardization (CEN) accepted ISO8768:1986 as European Standard EN 28768:1992. As a consequence of implementing the European Standard this British Standard is renumbered as BSEN 28768 and any reference to BS 4826-14 should be read as a reference to BSEN28768. Terminology and conventi

10、ons. The text of the International Standard has been approved as suitable for publication as a British Standard without deviation. Some terminology and certain conventions are not identical with those used in British Standards; attention is drawn especially to the following. The comma has been used

11、as a decimal marker. In British Standards it is current practice to use a full point on the baseline as the decimal marker. Wherever the words “International Standard” appear, referring to this standard, they should be read as “Part of BS4826”. The Technical Committee has reviewed the provisions of

12、ISO 2233, to which reference is made in the text, and has decided that they are acceptable for use in conjunction with this standard. A related British Standard is BS 4826“Complete, filled transport packages” Part 2:1986 “Method of conditioning for testing”. A British Standard does not purport to in

13、clude all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Cross-references International Standard Corresponding British Standard ISO 2206:19

Following the positive result of the CEN/CS Proposal ISO 8768:1986 was submitted to the Formal Vote. The result of

23、 the Formal Vote was positive. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 1993, and conflicting national standards shall be withdrawn at the latest by May 1993.

25、pe and field of application This International Standard specifies a method for carrying out a toppling test on a complete, filled transport package which may be exposed to the danger of toppling during storage, transport and handling. The test may be used to assess the performance of a package in te

26、rms of its strength or the protection that it offers to its contents when it is subject to toppling. It may be performed either as a single test to investigate the effects of toppling or as part of a sequence of tests designed to measure the ability of the package to withstand a distribution system

27、that includes a toppling hazard. The test, which is complementary to the tests described in ISO 2244, ISO2248 and ISO 2876, may be used to investigate the performance of packages which are tall in relation to their base dimensions. It is also applicable to packages the height of which is small by co

28、mparison with base dimensions but which may be stored or transported resting on a side face in order to conserve storage/transport space (seeFigure 1 andFigure 2). The test is recommended for packages where the ratio of the longest to the shortest sides is of the order of 3 : 1 or greater. 2 Referen

30、ulum test). ISO 2248, Packaging Complete, filled transport packages Vertical impact test by dropping. ISO 2876, Packaging Complete, filled transport packages Rolling test. 3 Principle In simple testing, placing of the test package on a flat, horizontal surface and subjection of the package to an inc

31、reasing horizontal force applied at a position above its centre of gravity until it topples freely about a lower edge. The atmospheric conditions and package attitude are predetermined. 4 Apparatus 4.1 Impact surface, horizontal and flat, massive enough to be immovable and rigid enough to be non-def

32、ormable under test conditions. In normal circumstances, the impact surface provided shall be flat, so that no two points on its surface differ in level by more than 2mm; rigid, so that it will not be deformed by more than 0,1mm when an area of 100mm 2is loaded statically with10kg anywhere on the sur

33、face; sufficiently large to ensure the test package falls entirely upon the surface. It shall have a mass at least50times that of the heaviest package to be tested. NOTEA concrete floor at least 150mm thick is suitable provided it complies with the above requirements. 4.2 Means of loading, capable o

34、f applying a horizontal force to the vertical faces of the test package at a particular height above the centre of gravity and of sufficient force to cause toppling without causing the package to slide on the horizontal surface. 5 Package preparation The test package shall normally be filled with it

35、s intended contents. However, under certain circumstances, simulated or dummy contents may be used on condition that the dimensions and physical properties of such contents shall be as close as possible to those of the intended contents. Ensure that the test package is closed normally, as if ready f

36、or distribution. If simulated or dummy contents are used, ensure that the normal method of closure is still employed. 6 Conditioning The package shall be conditioned in accordance with one of the conditions described inISO2233. 7 Procedure Whenever possible the test shall be carried out in the same

37、atmospheric conditions as used for conditioning, where this is critical to the materials or application of the package. In other circumstances, the test shall be carried out in atmospheric conditions which are as near as practicable to those used for conditioning. 7.1 Place the test package in the p

38、redetermined attitude (i.e. standing on one of its smaller faces) on the impact surface (4.1).EN 28768:1993 4 BSI 08-1999 7.2 Using the means of loading provided (4.2), apply increasing force to a vertical face above the centre of gravity (or at an upper edge) so that the test package rotates about

39、the opposite lower edge until a point of balance is reached. Then permit it to overbalance without thrust so that it falls freely onto the face opposite the face to which the force is applied. NOTEFor smaller packages, which can be handled manually, the toppling force may be applied by hand. For lar

40、ger packages, a mechanical means of loading may be necessary, i.e. a hydraulic ram or a cable or winch. 7.3 Examine the package and record any external signs of damage. 7.4 Repeat the test with the package standing on, or impacting onto, other appropriate faces. In the case of tall packages, the rep

41、eat tests shall be carried out with the package standing on its normal base and toppling onto each side face in turn (seeFigure 1). In the case of flat packages (or tall packages where the normal base is not defined), the tests shall be carried out with the package standing on each smaller face in t

42、urn and impacting onto each of the largest faces (seeFigure 2). Table 1 andTable 2 give appropriate sequences for tall packages and flat packages, respectively. For the designation of the faces referred to in the tables, see ISO2206. 7.5 On completion of the test sequence, the test package and conte

43、nts shall be examined for damage. 8 Test report The test report shall include the following particulars: a) reference to this International Standard; b) number of replicate packages tested; c) full description of the package, including dimensions, structural and material specification of the package

44、 and its fittings, cushioning, blocking, closure or reinforcing arrangements; d) description of contents if simulated or dummy contents were used, full details shall be given; e) gross mass of the package and mass of contents, in kilograms; f) relative humidity, temperature and time of conditioning;

45、 temperature and relative humidity of test area at time of test; whether these values comply with the requirements of ISO2233; g) the sequence of attitudes in which the package was tested, using the method of identification given in ISO 2206; h) type of loading apparatus used and, if known, the heig
