18、edevr 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 subject for
19、 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 (IEC) on a
20、ll 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 International
21、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. Intern
22、ational Standard ISO 2875 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 third edition cancels and replaces the second edition (ISO 2875:1985) which has
23、 been technically revised.

24、NDADR ISO 5782:(0002)E ISO 0002 All irhgts seredevr 1 Packaging Complete, filled transport packages and unit loads Water-spray test 1 Scope This International Standard specifies a method for testing the resistance of a complete, filled transport package or a unit load to water spray or the protectio
25、n it gives to its contents from water spray. It may also be used to precondition a complete, filled transport package or a unit load prior to another test to investigate reduction in strength caused by exposure to water. The test is performed on the test specimen as prepared for transport and may fo
26、rm part of a test sequence. 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
27、. However, parties to 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 IS
28、O and IEC maintain registers 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 purpos
29、es of this International Standard, the following term and definition applies. 3.1 test specimen a complete, filled transport package or unit load 4P r i n c i p l e The test specimen is placed in a test area and its top surface sprayed with water maintained at a constant temperature at a specified r
30、ate for a specified period. Each area of the surface is sprayed either continuously (method A) or intermittently (method B). ENISO2875:20021ISO 5782:(0002)E 2 ISO 0002 All irhgts seredevr 5 Apparatus and conditions 5.1 Test area conditions, shall be as follows: insulated and heated, when necessary,
31、to allow temperature to be controlled, fitted with a floor grating and an outlet of sufficient capacity to drain off the water as it is sprayed so that the test specimen does not stand in a pool of water. The grating shall not, through lack of rigidity or having too wide a mesh, cause deformation of
32、 the test specimen; height, sufficient to give a distance of at least 2 m between the spray nozzles (5.2) and the nearest point on the test specimen, so that the drops fall vertically. The dimensions of the floor shall be at least 50 % greater than those of the base of the test specimen. 5.2 Sprays,
33、 adjustable in height and fitted with nozzles of a design allowing water to fall vertically at a rate of (100 20) l/m 2 h onto a horizontal area 2 m below the nozzles, sufficiently uniformly to meet the requirements of the calibration test in 7.1, arranged in accordance with method A or method B as
34、follows: method A (continuous spraying): an array of sprays, fixed in position above the test specimen, after adjusting for height; method B (intermittent spraying): a row or rows of sprays across the width of the test specimen, capable of traversing a distance greater than the length of the test sp
35、ecimen at a constant velocity to meet the requirements of 7.1, with the interval between successive sprayings being less than 30 s. 5.3 Water supply system, supplying water at the required temperature (within a range of 5 C and 30 C) and at the rate and pressure required by the spray nozzles (5.2).
36、NOTE Figure 1 shows an example of apparatus configured appropriately for the operation of these tests. 6 Test specimen preparation Fill the test specimen with its intended contents and ensure that the test specimen is closed normally, as if ready for distribution. NOTE 1 Simulated or substitute cont
37、ents 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. The closure should still be as for distribution. NOTE 2 Conditioning, where appropriate, should be carried out in accordance with ISO 2233. ENISO2875

39、2:(0002)E 4 ISO 0002 All irhgts seredevr 7 Procedure 7.1 Calibration 7.1.1 The sprays (5.2) shall be mounted 2 m above the surface of the floor, with nozzles directed vertically downwards. 7.1.2 Sufficient identical open-top containers, of a design having an aperture area between 0,25 m 2 and 0,5 m
40、2 and height between 0,25 m and 0,5 m, shall be placed uniformly on the surface of the floor to cover at least 25 % of its area. 7.1.3 The sprays shall then be turned on and the times taken for the first and last containers to fill to overflowing shall be measured. 7.1.4 The time taken for the first
41、 to overflow shall not exceed that represented by a rate of 120 l/m 2 h; that of the least shall not be less than that represented by 80 l/m 2 h. 7.2 Test 7.2.1 Adjust the height of the sprays (5.2) to give a vertical distance of at least 2 m between the spray nozzles and the nearest point on the te
42、st specimen. Operate the sprays until the entire system has reached equilibrium. Unless otherwise specified, the temperature of the spray water and test area (5.1) shall be between 5 C and 30 C. 7.2.2 Place the test specimen centrally in the test area, in the predetermined position and at the predet
43、ermined temperature so that the water falls vertically on the test specimen. Operate the sprays continuously, as calibrated, for the specified period. 7.2.3 Examine the test specimen and its contents for any reduction in protective properties and/or infiltration of water. 8 Test report The test repo
