It supersedes BS4826-4:1972 which is withdrawn. In1992 the European Committee for Standa
9、rdization (CEN) accepted ISO2248-1985 as European Standard EN22248:1992. As a consequence of implementing the European Standard this British Standard is renumbered as BSEN22248 and any reference to BS4826-4 should be read as a reference to BSEN22248. Terminology and conventions. The text of the inte
10、rnational 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 as a decimal marker. In B
11、ritish 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 “British Standard”. The Technical Committee has reviewed the provisions of ISO2233, a new edition
12、of which is currently in preparation and 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 BS4826 “Complete, filled transport packages” Part2:1986 “Method of conditioning for testing”. A British S
13、tandard does not purport to include 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-reference International standard Corresponding

24、nd, United Kingdom.BS4826-4:1986 BSI 01-1999 3 1 Scope and field of application This International Standard specifies a method for carrying out a vertical impact test on a complete, filled transport package by dropping. It may be performed either as a single test to investigate the effects of vertic
25、al impact or as part of a sequence of tests designed to measure the ability of a package to withstand a distribution system that includes a vertical impact hazard. 2 References ISO2206, Packaging Complete, filled transport packages Identification of parts when testing.

26、illed transport packages Conditioning for testing. 3 Principle Raising of the test package above a rigid plane surface and releasing it to strike this surface (the“impact surface”) after a free fall 1) . The atmospheric conditions, the height of drop and the attitude of the package are predetermined
27、. 4 Apparatus 4.1 Lifting arrangement, which will not damage the test package during either lifting or release. 4.2 Means of holding the test package prior to release in its predetermined attitude. 2) 4.3 Release mechanism, to release the test package in such a way that its fall is not obstructed by
28、 any part of the apparatus before striking the impact surface (4.4). 4.4 Impact surface, horizontal and flat, massive enough to be immovable and rigid enough to be non-deformable under test conditions. NOTEIn normal circumstances, the impact surface provided shall be integral with a mass at least50
29、times that of the heaviest package to be tested; flat, such that no two points on its surface differ in level by more than2mm; rigid, such that it will not be deformed by more than0,1mm when an area of100mm 2is loaded statically with10 kg anywhere on the surface; sufficiently large to ensure that th
30、e test package falls entirely upon the surface. In addition, the apparatus shall meet the requirements and tolerances of clause7. 5 Package preparation The test package shall normally be filled with its intended contents. However, simulated or dummy contents may be used, on condition that the dimens
31、ions 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 for distribution. If simulated or dummy contents are used, ensure that the normal method of closure is still employed. 6 Conditi
32、oning The package shall be conditioned in accordance with one of the conditions described in ISO2233. 7 Procedure Whenever possible the test shall be carried out in the same atmospheric conditions as used for conditioning, where this is critical to the materials or application of the package. In oth
33、er circumstances, the test shall be carried out in atmospheric conditions which are as near as practicable to those used for conditioning. 7.1 Lift the test package and hold it in the predetermined attitude (see annex) at a height within 2% of the predetermined drop height as defined by the distance
34、 between the lowest point on the package at the time of release and the nearest point on the impact surface (4.4). 7.2 Release the test package from its predetermined attitude within the following tolerances: for face or edge drops:2 maximum angle between the impacting face, or edge, and the horizon
35、tal surface; for edge or corner drops: the angle between a prescribed surface of the package and the horizontal surface 5 or 10% of the angle, whichever is the greater. The velocity at impact shall be within 1% of that which would be achieved by a free fall. 1) In some circumstances, a completely fr
36、ee fall may not be possible; in such circumstances, the impact velocity shall be within1% of that which is achieved by a free fall. 2) The difference in behaviour of a sack, for example, suspended from the top or supported below in an end drop, could be significant. In such instances, the method of
37、holding the package before dropping shall be described in the test report.BS4826-4:1986 4 BSI 01-1999 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, includ
38、ing dimensions, structural and material specifications of the package 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 package and mass of contents, in kilog
39、rams; f) relative humidity, temperature and time of conditioning, temperature and relative humidity of test area at time of test; whether these values comply with the requirements of ISO2233; g) the attitude in which the package was tested, stated in one of the ways given in the annex; h) drop heigh
40、t, in millimetres; j) type of apparatus; k) any deviations from the test method described in this International Standard; m) a record of the result, with any observations which may assist in correct interpretation; n) date of the test; p) signature of tester.BS4826-4:1986 BSI 01-1999 5 Annex The pre
41、determined attitude of the test package shall be expressed in one of the following ways, using the method of identification given inISO2206. NOTEWhere bungs, enclosures or fittings are present, the attitude at impact may be related to their position. A.1 Parallelepipedal packages A.1.1 Impact on a f
42、ace State face1,2,3, etc. A.1.2 Impact on an edge State edge12,23,34, etc. and the angle between one of two surfaces forming the edge and the plane of the impact surface; or state the edge, and that the centre of gravity of the test package tested shall be vertically above the point of impact; or st
43、ate the edge, and that the two parallel edges of the test package nearest to the impact edge shall lie in a horizontal plane. A.1.3 Impact on a corner State corner125,346, etc. and the angles between two of the faces forming the corner and the plane of the impact surface; or state the corner, and th
44、at the centre of gravity of the test package shall be vertically above the point of impact. A.2 Cylindrical packages of circular cross-section In all instances, the centre of gravity of the test package shall be vertically above the point, line or plane of impact with the impact surface. A.2.1 Impac
45、t on top or bottom faces. A.2.2 Impact at any of the points 1,2,3 etc., on either the edge or rim. A.2.3 Impact on any of the lines12, 34, etc., parallel to the axis of the cylinder. A.3 Sacks and bags The centre of gravity of the sack shall be vertically above the face, end or side involved in the
46、impact. A.3.1 Impact on a face State face1 or3. A.3.2 Impact on an end State end5 or6. A.3.3 Impact on a side State side2 or4. A.4 Miscellaneous packages The attitude of the test package shall be based on the most appropriate attitudes given in clausesA.1, A.2 andA.3.6 blankBS4826-4:1986 BSI 01-1999
