It supersedes BS IS0 12W1994 which is withdrawn. The UK participation in its preparation was entrusted by Technical Co

5、urs. Apparatus 4.1 Compression tester, motor-driven, platen-type, capable of applying load through uniform movement of one or both platens at a relative speed of 10 mm/min 2 3 mm/min. NOTES 1 The comparison between results obtained from apparatus operated at other speeds (for example 12,5 mdmin I 2,
6、5 mdmin) and results obtained at 10 mdmin 2 3 mmlmin is not recommended. 2 For certain packagings, such as metal drums or wooden crates, lower speeds may be required to prevent load peaks in excess of the predetermined value. 4.1.1 Platens Each platen shall be - flat: a) with a tolerance of 1 part i
7、n 1 O00 for surface areas 1 m2, such that when placed horizontally the difference in height between the lowest and highest points of the platen does not exceed 1 mm; - dimensioned so as to extend over the whole area of that side of the test package or interposed devices with which it is in contact;

(Revision of IS0 2233:1986) 1 STD.BSI BS EN IS0 L204B-ENGL 2001 3b24bb9 0892206 591 EN IS0 12048:2000 - rigid, so as not to deform by more than 1 mm at any point when the tester applies a load of 75 % of its maximum rating, either to a centrally placed 100 mm X 100 mm X 100 mm bl
9、ock having suf- ficient strength to accept the load without failure, or to four similar blocks placed at the four corners, in the case of swivel-mounted platens. One platen shall remain horizontal, within a tolerance of two parts per 1000, at all times during the test. The other platen shall be eith
10、er rigidly mounted so as to remain horizontal within two parts per 1 O00 at all times during the test, or be held by a universal joint at its centre and so be free to tilt in any direction. The working surfaces of the platens may be locally recessed for fixing bolts etc. 4.1.2 Means of applying a pr
11、edetermined load for a predetermined time, with a fluctuation not exceeding +- 4 % of the predetermined load and with no more relative movement of the platens than is necessary to maintain this load during any vertical displacement of the upper platen. 4.2 Recording device or other means of indicati
12、ng applied load and platen displacement, with a percentage of error not exceeding 2 % of the load and an accuracy for recording platen displacement of 2 1 mm. 4.3 Means of measuring package dimensions with an accuracy of I 1 mm. 5 Package preparation The test package shall normally be filled with it
13、s intended contents. However, 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 for distribution. If simulate
14、d 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 sets of conditions given in IS0 2233. 7 Procedure Wherever possible the test shall be carried out in the same atmospheric conditions
15、 as used for condition- ing, 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. When possible, carry out the test on five replicate pac
16、kages. 7.1 Compression test 7.1.1 Weigh the package and its contents separately, fill the package and measure the external dimensions of the filled package. 7.1.2 Place the test package centrally on the lower platen of the test machine (4.11, in the predetermined attitude. When the compression load
17、is not to be applied over the whole surface of the package which is being tested, appropriate devices should be suitably interposed between the package and platen of the compression tester in order to simulate the conditions met in distribution systems when applying these compression loads. 7.1.3 Ap
18、ply the load by relative movement of the platens at the appropriate speed, in such a way that peaks in excess of the predetermined load do not occur, until the predetermined value is reached or until collapse occurs, whichever is first. If collapse occurs first, record the value of the load reached.
19、 In measuring deformation, the initial reading (the datum point), unless otherwise specified, shall be taken at an initial load which is a function of the expected average compression load according to table 1. Table 1 - Datum points Average compression load N 101 -200 201 - 1 O00 1 O01 -2 O00 2 O01

If collapse occurs first, record the value of the time elapsed. 7.1.5 Remove the load by

NOTE4 Where it is desired to measure the ability of a complete, filled transport package to resist external cornpressive loads applied during stacki

NOTES 5 At any time during the test it may be necessary to measure dimensions (see annex A
26、). 6 Appropriate profiles representative of particular loading conditions may be inserted between platens and package as required. 8 Testreport The test report shall include the following information: f) gross mass of the package and mass of contents, in kilograms; g) relative humidity, temperature
27、and time of conditioning; temperature and relative humidity of test area at time of test; whether these values comply with the requirements of IS0 2233; hl the attitude in which the package was tested, using the method of identification given in IS0 2206; i) type of test apparatus used, including wh
