18、hgts seredevr iii Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a sub
19、ject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (I
20、EC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an Intern
21、ational Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights
22、. International Standard ISO 2233 was prepared by Technical Committee ISO/TC 122, Packaging, Subcommittee SC 3, Performance requirements and tests for means of packaging, packages and unit loads (as required by ISO/TC 122). This fourth edition cancels and replaces the third edition (ISO 2233:1994),
23、which has been technically revised. Annex A forms a normative part of this International Standard. ENISO2233:2001 ISO 3322:(0002)E iv ISO 0002 All irhgts seredevr Introduction It is the responsibility of the user of this International Standard to establish appropriate health and safety practice in a

25、lled, transport packages and unit loads. 2 Term and definition For the purposes of this International Standard, the following term and definition applies. 2.1 test specimen a complete, filled transport package or unit load 3P r i n c i p l e The test specimen is exposed to predetermined atmospheric
26、conditions for a predetermined period of time. 4 Atmospheric conditions One or more of the conditions given in Table 1 shall be selected.

28、ifference of ten measurements distributed about the nominal value over at least 1 h shall be 3 C. For all other conditions the maximum permissible difference shall be 2 C. 5.1.2 Tolerance on the mean For all conditions, the tolerance on the mean in relation to the nominal value shall be 2C. NOTE 1 W
29、hen using condition 4, care should be taken to ensure that the dew point is not reached. NOTE 2 Temperature tolerances quoted are not necessarily those required to maintain the required tolerances on relative humidity; closer temperature tolerances may therefore be necessary in order to comply with
30、the tolerances required for relative humidity. 5.2 Relative humidity 5.2.1 Tolerance on peak values For all conditions with a humidity requirement, the maximum permissible relative humidity difference of ten measurements distributed about the nominal value over at least 1 h shall be 5%RH. 5.2.2 Tole
31、rance on the mean For all conditions, the tolerance on the mean in relation to the nominal value shall be 2 % RH. NOTE 1 The mean value of relative humidity may be obtained by taking the average of a minimum of ten measurements over a period of 1 h, or may be derived from a continuous instrument tra
32、ce. NOTE 2 The tolerance of 5 % RH is quoted as this represents the maximum variation to be expected in conditioning chambers. Modern, well designed, conditioning chambers are capable of maintaining 2 % RH. The response of most test specimens to changes in atmospheric moisture is relatively slow com
33、pared with the fluctuations of relative humidity within the chamber and, provided that the relative humidity within the working space, taken over any 1 h period during the duration of the test, lies within 5 % of the specified relative humidity, it may be assumed that the wider fluctuations, such as
34、 may occur on opening the door, have had little effect on the moisture content of the package. 6 Apparatus 6.1 Conditioning chamber, having a working space the temperature and humidity of which is continuously recorded and which can be maintained at the specified conditions within the control tolera
35、nces given in clause 5. The working space is that part of a conditioning chamber within which the specified controlled conditions are maintained. The boundaries of this space shall be specified for each chamber. 6.2 Drying chamber, if necessary, to reduce the moisture content of certain test specime
36、ns to below that which will be attained by conditioning. 6.3 Measuring and recording apparatus, sufficiently sensitive and stable to allow measurement of temperature to an accuracy of 0,1 C and relative humidity to 1 %. For the purposes of this International Standard, the record is deemed continuous
37、 if the period between individual readings is not greater than 5 min. ENISO2233:2001 ISO 3322:(0002)E ISO 0002 All irhgts seredevr 3 The recording equipment shall have sufficient speed of response to record accurately, to the precision stated above, changes in temperature of 4 C per minute and chang
38、es in relative humidity of 5 % per minute. 7 Procedure 7.1 Select the temperature and relative humidity conditions most appropriate to the transport and storage of the test specimen to be tested. Place the test specimen within the working space of the conditioning chamber (6.1) and expose it to the
39、specified conditions for a minimum period which shall be selected from 4 h, 8 h, 16 h, 24 h, 48 h or 72 h or from 1 week, 2 weeks, 3 weeks or 4 weeks. 7.2 Support the test specimen in such a way that the conditioning atmosphere has free access to the top, sides and at least 75 % of the base. The con
40、ditioning period is deemed to start 1 h after the specified conditions have been regained. 7.3 When the test specimen is constructed of materials, such as fibreboard, that are known to show a hysteresis effect in their characteristics, it may be necessary to pre-dry before conditioning. This shall b
41、e done by placing the test specimen for a minimum period of 24 h in the drying chamber (6.2) in conditions such that, when transferred to the test conditions, it will approach equilibrium by taking up moisture. This is not necessary when the specified relative humidity is 40 % or below. 8 Test repor
42、t The test report of tests on conditioned, complete, filled transport packages and unit loads, such as impact tests, stacking test and vibration tests, shall include the following information: a) a reference to this International Standard; b) the details of any pre-drying; c) the conditions (see Tab
43、le 1) and time used for conditioning; d) the temperature and relative humidity of the test area at the time of test; e) any deviation from this International Standard.

44、ture and relative humidity A continuous record of temperature or relative humidity will show a cyclic variation. It is therefore necessary to determine precise values which define both the level and variation of these properties. Consider the typical record given in Figure A.1. Key 1 Nominal value 2
