20、ean 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 incre
21、ase 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.

30、lowing terms and definitions apply. 3.1 compatibility ability for trays and closures to fit well onto each other and ability of easy nesting into each other as well as separating of trays and closures from each other 3.2 durability ability of a tray and closure to withstand conditions to which it is
31、 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 items classified according to its physical characteristics such as weight and dimensions 3.5 nestability ability
32、 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) height) 3.6 recyclability ability to recover the material of a discarded tray (measured as the content of re
33、cycled 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) within a pre-defined temperature range 3.9 tray primary container with closure for the carriage of letter mail
34、 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 Clause 4. 4.2 Tray size requirements Minimum internal tray dimensions shall accommodate mail of the following
35、 sizes with ease of handling: Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 19/09/2011 08:13, Uncontrolled Copy, (c) BSIBS 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 Trays and
36、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 represents a
37、 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 maximum
38、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 strapping
39、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 appropriate flammab
40、ility 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. 4.3.8 Nes
41、tability 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. Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 19/09/2011 08:13, Uncontrolled Copy, (c)

Trays that are stacked shall be placed on a flat, horizontal and level surface and r
43、emain stable at up to 1,8 m stacking height. 4.3.11 Tare weight The tray and closure shall 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 tha
44、n 10 % of the maximum filled weight of the tray. The mail load capacity of the tray is determined 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 resist
45、ance Trays shall be capable of being handled at extreme temperatures, as specified in EN ISO 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
46、 test on the edge of the loaded tray with 10 kg gross weight from 1 m high). 4.3.13 Weather 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 te
47、sting methods were designed to represent simulation of real life usage and handling in an 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. Li
48、fe span is expressed as number of cycles successfully completed in the durability test (5.3.10), 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
49、, although in general the higher the number of cycles the higher the economic life span. Economic 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
