7、Part of BS 4826 has been prepared under the direction of the Packaging and Freight Containers Standards Committee. It is identical with ISO8474:1986 “Packaging Complete, filled transport packages Water immersion test”, published by the International Organization for Standardization (ISO). In 1992 th

8、e European Committee for Standardization (CEN) accepted ISO8474:1986 as European Standard EN28474:1992. As a consequence of implementing the European Standard this British Standard is renumbered as BSEN28474 and any reference to BS4826-13 should be read as a reference to BSEN28474. Terminology and c

9、onventions. 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. Wherever the word

10、s “International Standard” appear, referring to this standard, they should be read as “Part of BS4826”. Cross-reference. The Technical Committee has reviewed the provisions of ISO2233, to which reference is made in the text, and has decided that they are acceptable for use in conjunction with this s

11、tandard. A related British Standard is BS4826 “Complete, filled transport packages” Part 2:1986 “Method of conditioning for testing”. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. C

12、ompliance with a British Standard does not of itself confer immunity from legal obligations.

It may be used to pre-cond

23、ition a package prior to other tests, to investigate reduction in strength caused by exposure to water or to investigate the protection the package gives to its contents from water immersion. The test is principally intended for packages which are waterproof or which are intended to provide some deg

24、ree of “waterproofness”. The test is performed on the package as prepared for transport and may form part of a test sequence. 2 Reference ISO 2233, Packaging Complete, filled transport packages Conditioning for testing. 3 Principle Conditioning of the package, followed by complete immersion in water

25、, removal and draining and drying in the conditioning atmosphere. The time of immersion, time of draining and drying and the atmospheric conditions are predetermined. 4 Apparatus 4.1 Test area, conditioned in such a manner that evaporation from the wet package and the surface of the water in the wat

26、er tank(4.2) do not significantly change the atmospheric conditions. 4.2 Water tank, sufficiently large for the test package to be immersed completely under water with the water level at least100mm above the package. The tank shall be designed so that it can be easily filled with water and emptied a

27、nd the water maintained at the temperature specified in7.1. 4.3 Immersion equipment to contain the test package loosely. It shall be capable of being lowered and lifted. A cage of appropriate dimensions is suitable for this purpose. NOTESome means of hoisting, for example an electric or manual hoist

28、, may be fitted over the water tank to lower and raise the test package conveniently. 4.4 Rigid grill, capable of supporting the wet test package without deformation and positioned so that air is able to flow freely beneath it. The rods or bars from which it is made shall not occupy more than10% of

29、the surface area. 5 Package preparation The test package shall normally be filled with its intended contents. However, under certain circumstances, simulated or dummy contents may be used, on condition that the dimensions and physical properties of the such contents shall be as close as possible to

30、those of the intended contents. Ensure that the test package is closed, and labelled or marked normally, as if ready for distribution. If simulated or dummy contents are used, ensure that the normal methods of closure, and labelling or marking are still employed. 6 Conditioning The package shall be

31、conditioned in accordance with one of the conditions specified in ISO2233. 7 Procedure 7.1 Fill the tank(4.2) to an appropriate depth with water and ensure that the water temperature is within 2 C of the temperature selected from a range from 5to40 C. 7.2 The test shall be begun within5min of removi

32、ng the package from the atmospheric conditions selected for clause6. 7.3 Using the immersion equipment (4.3), lower the package into the water at a rate not greater than300mm/min. Alternatively the package may be placed in the empty water tank which is then filled to the required level. The immersio

33、n process shall be considered to be complete when the water level is at least100mm above the top of the package. Keep the package immersed for a period which shall be selected from 5, 15 or 30 min, or from 1, 2 or 4h. 7.4 After the predetermined immersion period, raise the package completely out of

34、the water at a rate not exceeding300mm/min. Place the package on the grill(4.4) positioned so that all surfaces of the package are exposed to the atmospheric conditions specified in clause6. Allow the package to be exposed for a period which shall be selected from 4, 8, 16, 24, 48 or 72 h or from 1,

35、 2, 3 or 4 weeks.EN28474:1992 4 BSI 10-1999 7.5 Note any obvious damage sustained by the package and its contents as a result of immersion in water and subsequent draining and drying, and any other difference in appearance, including labels and markings. 8 Test report The test report shall include t

36、he following information: a) reference to this International Standard; b) the number of replicate packages tested; c) a full description of the package, including dimensions, structural and material specifications of the package and its fittings, cushioning, blocking or reinforcing arrangements; d)

37、a description of contents if simulated or dummy contents were used, full details shall be given; e) the gross mass of the package and the mass of the contents, in kilograms; f) the relative humidity, temperature and time of conditioning; a statement whether these values comply with the requirements

38、of ISO2233; g) the temperature of the test area and of the water at the time of immersion; h) the orientation of package relative to the floor during immersion and draining, etc.; i) the duration of immersion in water; j) the duration of the draining and drying method; k) any deviations from the tes

39、t method specified in this International Standard; l) a record of the result, with any observations which may assist in correct interpretation; m) the date of the test; n) the signature of the person responsible for the test.BSEN28474:1993 BSI 10-1999 Publication referred to See national foreword.BS
