BS EN 14482:2010EN 14482:2010 (E) 5 Introduction The
18、 European Union Commission stressed already in its Green paper on postal services in 1992 the need to establish common rules for the development of community postal services and the improvement of quality of service. Furthermore the Commission has acknowledged the need for technical harmonisation to
19、 increase the interoperability of postal networks in the Member States and has given CEN a mandate to define fields where such harmonisation could be useful and suggest priorities and timescales. BS EN 14482:2010EN 14482:2010 (E) 6 1 Scope This European Standard specifies the performance requirement
20、s and testing methods for standard letter mail trays, as specified in the classification below. The trays should be used to facilitate the exchange of international mail. The technical specification of the trays should be such that the performance requirements specified herein are met and tests spec
21、ified herein successfully completed. The technical specifications of trays as such however, are beyond the scope of this standard. This standard covers a one-size universal letter mail tray suitable for carrying C4, C5 and C6 mail: Table 1 Letters (maximum accepted sizes) Height Width C4 353 mm 250
22、mm C5 173 mm 250 mm C6 120 mm 250 mm The trays are suitable for containing C4 mail stacked in a horizontal plane and for stacking C5 and C6 mail vertically. 2 Normative references The following referenced documents are indispensable for the application of this document.

28、closures from each other 3.2 durability ability of a tray and closure to withstand conditions to which it is subjected (when tested) 3.3 friction capacity to prevent sliding on an inclined low friction conveying surface specified as the coefficient of friction 3.4 letter mail category of postal item
29、s classified according to its physical characteristics such as weight and dimensions 3.5 nestability ability of trays and closures to fit together one partially inside the other (measured as the ratio of the number of trays and closures which can be nested in a stack for one tray (tray and closure)
30、height) 3.6 recyclability ability to recover the material of a discarded tray (measured as the content of recycled material in a tray) 3.7 stackability ability to be stacked and fully palletisable when filled with letter mail 3.8 temperature resistance ability to maintain shape (when conditioned) wi
31、thin a pre-defined temperature range 3.9 tray primary container with closure for the carriage of letter mail 3.10 weather resistance ability to remain serviceable (when conditioned) under specific weather conditions 4 Requirements 4.1 General The mail tray shall meet all the requirements stated in C
32、lause 4. 4.2 Tray size requirements Minimum internal tray dimensions shall accommodate mail of the following sizes with ease of handling: BS EN 14482:2010EN 14482:2010 (E) 8 Table 2 Height Width C4 353 mm 250 mm C5 173 mm 250 mm C6 120 mm 250 mm 4.3 Tray performance requirement 4.3.1 Compatibility T
33、rays and closures shall fit well onto each other, nest easily into each other and separate well from each other without the use of undue force. 4.3.2 Compression The trays shall meet a minimum compression strength requirement of 180 kg at a deflection of less than 10 mm before failure. NOTE This rep
34、resents a five high stack of trays each weighing 10 kg and a safety factor of 4,5, as specified in EN ISO 12048. 4.3.3 Durability Trays shall withstand drop, vibration and crushing simulations as per the following: Each tray shall withstand a minimum average of 70 cycles with a standard deviation of
35、 maximum 20 %, as specified in EN ISO 2247, EN 22248, EN ISO 4180. 4.3.4 Closure The closure of the tray is to provide security during transit and handling. The closures shall fit well on the tray to prevent tampering with the content. The closures shall be enclosed tightly to the tray by means of s
36、trapping in both directions, once over the width and once over the length of the tray. 4.3.5 Flammability Trays manufactured from plastic material shall meet requirements as specified in EN 60695-11-20. Trays made from alternative materials shall meet similar requirements when tested with appropriat
37、e flammability tests. 4.3.6 Friction The friction coefficient between tray and conveyor surface as specified in 5.3.6 shall not be lower than 0,31. 4.3.7 Handles/handholds Handles/handholds shall be designed for ergonomically comfortable handling, with no sharp edges and as referenced in EN 1005-2.
38、4.3.8 Nestability Nesting ratio of trays and closures to the one “tray and closure height“ shall be a minimum of 1:5. The better the nesting ratio the lower the transport cost for moving empty trays and closures. BS EN 14482:2010EN 14482:2010 (E) 9 4.3.9 Recyclability Trays should be manufactured fr
39、om a material which is recyclable as specified in EN 13430. 4.3.10 Stackability Trays shall be stackable and inter-stackable. Trays that are stacked shall be placed on a flat, horizontal and level surface and remain stable at up to 1,8 m stacking height. 4.3.11 Tare weight The tray and closure shall
40、 meet the tray dimensions and durability requirements specified with a tare weight remaining as light as possible. Because of the impact of tare weight on transport cost, the tare weight shall not be higher than 10 % of the maximum filled weight of the tray. The mail load capacity of the tray is det
41、ermined by the minimum tray dimensions specified in 4.2. The average tare weight shall not exceed 1 050 g and the standard deviation shall not be higher than 1 % of the average weight. 4.3.12 Temperature resistance Trays shall be capable of being handled at extreme temperatures, as specified in EN I
42、SO 2233: from - 35 C to 70 C there shall be materials stability such that the material shall maintain its essential shape for up to 8 h; at - 35 C the trays shall be resistant to the drop test (perform the drop test on the edge of the loaded tray with 10 kg gross weight from 1 m high). 4.3.13 Weathe
43、r resistance Water spray exposure The tray and closure shall be weather resistant with no more than 3 % ingress of water as specified in EN ISO 2875. 5 Test method 5.1 Test methods introduction The following testing methods were designed to represent simulation of real life usage and handling in an
44、international mail exchange environment. The test methods intend to characterize the functionality, strength and life span of trays used in the exchange of international mail. The tests are laboratory tests. Life span is expressed as number of cycles successfully completed in the durability test (5.
45、3.10), which is meant to reflect the minimum number of trips the tray can make in real life before failure. The life span expressed as number of cycles is not meant to be an indicator for the economic life span, although in general the higher the number of cycles the higher the economic life span. E
46、conomic life span on the one hand is a function of materials / design / manufacture and is defined by the technical specification of the tray, and on the other hand it is a function of the equipment management determining circulation time and number of trays in circulation. These factors are outside
47、 the scope of this standard. The tests can be used as pre-production tests as well as postproduction tests. The test method allows for testing of trays and closures manufactured using different tools and by different manufacturers. BS EN 14482:2010EN 14482:2010 (E) 10 5.2 Test sampling and tray prep
48、aration A minimum of 50 samples, trays and closures, shall be made available to perform the tests. In case of a post-production test, the 50 samples shall be taken at random but in sequence, one from each production tool. The 50 samples shall be picked equally spread over the full production period.
49、 The samples supplied shall be marked with an indicator of the production date, the tool number and the name of the manufacturer. In case trays from more than one manufacturer are to be tested, each manufacturer shall provide 50 tray samples. At arrival on the test site all trays shall be numbered and ten samples shall be separated for the compatibility, nestability and stackabil
