10、 field of application This International Standard specifies two methods for testing complete, filled transport packages for compression resistance. The test may be used to assess the performance of a package in terms of its strength or of the protection it offers to its contents when it is subjected
11、 to compressive forces. It may be per- formed either as a single test to investigate the effects (defor- mation, collapse or failure) of compression or as part of a se- quence of tests designed to measure the ability of a package to withstand a distribution system that includes a compression hazard.
12、 NOTE - A test method using a compression tester to determine the stacking resistance of a package is given in IS0 2874. 2 References IS0 2206, Packaging - Complete, filled transport packages - Identification of parts when testing. IS0 2233, Packaging - Complete, filled transport packages - Conditio
13、ning for testing. IS0 2874, Packaging - Complete, filled transport packages - Stacking test using compression tester. 3 Principle Placing of the test package between the platens of a compres- sion tester, and compression, the load and platen displacement being recorded until failure occurs or predet
14、ermined values for load or displacement are reached. 4 Apparatus 4.1 Compression tester, motor-driven, mechanical or hydraulic, platen-type, capable of applying load through uniform movement of one or both platens at a relative speed of 10 f 3 mm/min. The platens shall be - flat, so that when placed
15、 horizontally the difference in height between the lowest and highest points does not ex- ceed 1 mm; - dimensioned so as to extend over the whole area of the panels with which they are in contact; - rigid, so as not to deform by more than 1 mm at any point when the tester applies a load of 75 % of i
16、ts maximum rating, either to a centrally placed 100 mm x 100 mm x 100 mm block having sufficient strength to accept this 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 two parts per 1 o00 a
17、t all times during the test. The other platen shall be either 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 platens suitable for testin
18、g packages with a length or width or diameter greater than 1 o00 mm may be locally recessed for fixing bolts, etc. 4.2 Recording device or other means of measurement, with a percentage of error for loads not exceeding f 2 % of the load and an accuracy of platen displacement of f 1 mm. 5 -Package pre
19、paration The test package shall normally be filled with its intended con- tents. 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 in- tended contents. Ensure that the test package
20、 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 Conditioning The package shall be conditioned in accordance with one of the conditions described in IS0 2233. 7 Procedure Whenever possible the te
21、st shall be carried out in the same at- mospheric 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 con- ditions which are as near as practicable to those used for con- diti
22、oning. CEN EN*E!2872 92 m 3404589 0040329 43T = Page 4 EN 22872 : 1992 7.1 Method 1 7.1.1 Place the test package centrally on the lower platen of the test machine (4.11, in the predetermined attitude. 7.1.2 Apply the load by relative movement of the platens at 10 f 3 rnm/min until the predetermined
23、value is reached or until premature collapse. In measuring deformation, the datum zero point shall be taken as the reading corresponding to a load of 220 N. 7.2 Method 2 Where it is desired to measure the ability of a complete, filled transport package to resist external compressive loads applied to
24、 opposite edges or corners of the package, the procedure is the same as in Method 1, but it is essential to use a tester in which the platens are not free to tilt. 8 Test report The test report shall include the following particulars : a) reference to this International Standard; b number of replica
25、te packages tested; c) full description of the package, including dimensions, structural and material specifications of the package and its fittings, cushioning, blocking, closure or reinforcing ar- rangements; d) description of contents - if simulated or dummy con- tents were used, full details sha
26、ll be given; e) gross mass of the package and mass of contents, in kilograms; 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 IS0 2233; g) the attitude in which the packag
27、e was tested, using the method of identification given in IS0 2206; h) load imposed, in newtons, and the duration of time of the package under load; j) location of points on packages and stage of test at which measurements were made; k) type of apparatus used, including whether the tester was mechan
28、ically or hydraulically operated and whether or not both platens were rigidly mounted; m) any deviations from the test methods described in this International Standard; n) a record of the result, including load/platen displace- ment recording, with any observations which may assist in correct interpretation: p) date of the test; q) signature of tester.
