ENISO2873:2002INTEANRTIONAL TSAADNDR ISO 2:378(0002)E 1 Packaging Complete, filled transport packages and unit loads Low pressure test 1 Scope This International Standard specifies a method for subjecting complete, filled transport packages and un
28、it loads to conditions of low air pressure similar to those encountered in aircraft. This method is applicable to complete, filled transport packages and unit loads which are intended to be transported in pressurized aircraft flying at any altitude and in unpressurized aircraft flying at 3 500 m or
29、less. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to
30、agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain reg
31、isters of currently valid International Standards. ISO 2206, Packaging Complete, filled transport packages Identification of parts when testing. ISO 2233, Packaging Complete, filled transport packages and unit loads Conditioning for testing. 3 Term and definition For the purposes of this Internation
32、al Standard, the following term and definition applies. 3.1 test item a complete filled transport package or unit load 4 Principle The test item is placed in a pressure chamber, and the pressure in the chamber reduced to that corresponding to an altitude of 3 500 m. This pressure is approximately eq
33、ual to that in pressurized aircraft flying at any higher altitude. The pressure is then held for a predetermined period after which it is permitted to return to ambient pressure. NOTE While the pressure is held for the predetermined period, the temperature may also be maintained to that correspondin
34、g to the same altitude (see annex A, Table A.1). ENISO2873:20022 5 Apparatus 5.1 Pressure vessel, of sufficient size to accommodate the test item, with pressure and temperature controls to meet the requirements of the procedure in clause 8. 6 Test item preparation Fill the test item with its intende
35、d contents and ensure that the test item is closed normally, as if ready for distribution. NOTE Simulated or substitute contents may be used on condition that the dimensions and physical properties of such contents are as close as possible to those of the intended contents. However, the closure shou
36、ld be the same as for distribution. 7 Conditioning The test item shall be conditioned in accordance with one of the conditions described in ISO 2233. 8 Procedure 8.1 Place the test item in the pressure vessel (see clause 5) and reduce the pressure at a rate not exceeding 150 mbar/min, until it reach
37、es 650 mbar ( 5 %). Maintain this pressure for the predetermined period. NOTE 1 mbar = 1 hPa = 0,1 kPa 8.2 Restore the pressure by allowing dry air at laboratory temperature to enter at such a rate that the increase in pressure does not exceed 150 mbar/min. NOTE If it is desired to study the effects
38、 of temperature as well as pressure in pressurized aircraft, the atmosphere in the vessel should be maintained at ( 8 1) C during the predetermined period. 9 Test report The test report shall include: a) a reference to this International Standard; b) the name and address of testing laboratory and na
39、me and address of customer; c) the unique identification of the report; d) the date of receipt of the test items and the date(s) of performance of the test; e) the name, title and signature of persons accepting test responsibility for the test report; f) a statement to the effect that the test resul
40、ts relate only to the items tested; g) a statement that the report shall not be reproduced, except in full, without the written approval of the testing laboratory; h) the number of replicate test items tested; ENISO2873:20023 i) a full description, including dimensions, structural and material speci
41、fications of the test item and its fittings, cushioning, blocking, closure and reinforcing arrangements, gross mass of the test item and the mass of the contents in kilograms; j) the description of contents, if simulated or substituted contents were used, full details shall be given; k) the relative
42、 humidity, temperature and time of conditioning; the temperature and relative humidity of the test area at the time of test; whether these values comply with the requirements of ISO 2233; l) the attitudes in which the test item was tested, using the method of identification given in ISO 2206; m) the
43、 temperature and pressure inside the pressure vessel, and the time for which they were maintained; n) any deviation from the test method described in this International Standard; o) a record of the result, including any observations which assist in the correct interpretation of the results. ENISO287
44、3:20024 Annex A (informative) Atmospheric conditions The temperature in the holds of pressurized aircraft rarely falls below 0 C. However the temperature of packages and unit loads on loading into the aircraft will depend on the ambient temperature experienced prior to loading as well as the subsequ
45、ent ambient temperature experienced in the hold prior to take off. These effects will persist for some time during flight. The same ambient temperatures can also affect the temperatures of packages and unit loads in unpressurized aircraft. When these aircraft fly above 3 500 m the pressure will drop
46、 to the values given in Table A.1, and the temperature of the packages and unit loads will be affected to some extent by outside air temperature at these altitudes depending on the length of the flight and the time/altitude profile of the flight.
