17、tandardization Institute (DIN). It is part of a complete normative concept to acquire and describe the loads acting on goods and influencing them during transport, handling and storage. This standard becomes significant when related to the realisation of the European Directive on Packaging and Packa

18、ging Waste (Directive 94/62 EC, 20 December 1994). This directive specifies requirements on the avoidance or reduction of packaging waste, and requires that the amount of packaging material is adjusted to the expected transportation load, in order to protect the transportation item adequately. Howev

19、er, this presumes some knowledge of the transportation loads occurring during shipment. At present, basic standards, based on scientifically confirmed values, which can adequately describe and characterize the magnitudes of transportation loads, especially in the domain of dynamic mechanical loads d

20、o not exist nationally or internationally. Reasons for this are mainly the absence of published data, insufficient description of the measurements or restrictions on the dissemination of this information. This standard will enable the measurement and evaluation of dynamic mechanical transportation l

21、oads, thus enabling the achievement of standardized and adequately documented load values. This series of standards consists of the following parts: Part 1: General requirements; Part 2: Data acquisition and general requirements for measuring equipment; Part 3: Data validity check and data editing f

22、or evaluation; Part 4: Data evaluation; Part 5: Derivation of Test Specifications; Part 6: Automatic recording systems for measuring randomly occurring shock during monitoring of transports.

23、:2007 (E) 5 1 Scope This standard gives guidelines for the derivation of test specifications from data acquired according to EN 15433-2, EN 15433-3 and EN 15433-4. NOTE To simulate transportation loads, it is helpful to work with standardized load assumptions that are based on the actual loads acqui

24、red according to EN 15433-2 up to EN 15433-4. The derivation of test specifications is based fundamentally on considerations concerning the reproduction of damage, whereby time compressed fatigue simulation in particular has to be considered for the determination of the test intensity. 2 Normative r

25、eferences The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. Not applicable 3 Derivation of test con

26、ditions The ideal way to simulate transportation loads is to use actual measured transportation loads. These are usually represented as acceleration-time functions and contain the overall dynamic mechanical load profile of the transport process. The duration of the simulation corresponds with the du

27、ration of the actual transportation. NOTE In practice, however, tests have to be performed by test laboratories, which do not have measured values for that particular case available. In such cases, a standard load should be used. If transport processes are to be time-compressed because the actual tr

28、ansport duration is too long, then the assumption concerning the time compression should comply with the state of the art. The time compression factor should be mentioned in the test report. 4 Parameters for the derivation of test conditions For each derivation of a test condition, the following par

29、ameters can have an influence on the derived result: transportation means; transportation route; duration of transportation; transportation conditions; viewed aspect of damage; dynamic mechanical particularities; other boundary conditions. NOTE For more details reference should be made to EN 24178:1

30、992 Complete, filled transport packages - Distribution trials - Information to be recorded For each derivation, the parameters that have been taken into consideration should be recorded, along with the cases for which they are valid. The derivation procedure chosen should also be recorded. Licensed

These procedures should be based on the s

32、tate of the art. NOTE 1 It is assumed that these procedures will continue to develop following publication of this standard. Clause 6 shows an example procedure that aims to break down the material through forced or fatigue rupture. NOTE 2 Any expert can perform the derivation of a test spectrum. De

33、rivations of test spectra should comply with the corresponding state of the art. In order to derive relevant test spectra, the measured acceleration-time signals should be analysed and evaluated according to EN 15433-2, EN 15433-3 and EN 15433-4. 6 Derivation of test spectra for failure mechanisms 6

34、.1 General Transportation damage due to material failure is usually based on forced or fatigue rupture. Standardised load profiles should be made available for such situations. In most cases, the acquired data are not suitable for testing purposes, since they represent only the momentary value of th

35、e load as it appears at any time during transport. Furthermore, due to cost reasons, the test duration has to be much shorter than the actual transportation duration. The guidelines given in this standard should therefore be used to derive a test specification. Before deriving a test specification f

36、rom analysed data, it should be ascertained that all power spectral density (PSD) plots are analysed according to EN 15433-4 and originate from that particular location of the load platform on the transportation means, producing at any time the severest load on the transported item. The longitudinal

37、 and lateral loads acting on the transported item should also be considered. In general, the spectra for the foreseen test specifications should be of no other transportation means, but those used to transport that particular item. This is because larger or smaller vehicles can show marked differenc

38、es compared to the one used for the actual transport. If a transportation route is unknown, and if the transported item is to be transported as a single item on different transportation means, then the spectra of the transportation means creating the most severe load should be used to simulate the t

39、ransportation load. If large quantities of a specific product have to be transported over long distances, it is essential to know the transportation route, the transportation means, the transportation speed, and the load factor (as a percentage of the maximum permissible payload). From these paramet

40、ers the load spectrum can be derived, which will result in a suitable transportation test and therefore also result in suitable transportation packing. An optimal simulation of the transportation load can be achieved if, besides the transportation means, the road sections are also considered. This m

41、eans that for a specific road transportation, the load spectra of a particular vehicle on different road categories, the driving duration on these same road categories, and the load factor of that particular vehicle are known. If sea transportation is performed, then the ship size and category, as w

42、ell as load factor, and the state of the sea and the time spent under those conditions, should be known. Hence it can be shown that a complete simulation is to be split proportionally into part simulations. Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 28/04/2008 03:47, Uncontrolled Copy, (

47、an essential influence on the transport load. Unsuitable test results can be caused by averaging the various transport loads over a complete transportation route on which the transport has passed. To prevent this, the transportation route should be split into different road categories, as shown in F

48、igure 1. For testing purposes, the intensity as well as the duration at which such intensity occurs on that particular road category, are relevant. NOTE Current road maps give sufficient information concerning the road categories that have to be travelled on, from the producer to the end-user of the

49、 transported item. From this information, the driving speed and duration of the transport, as well as the expected load on the transported item, can be estimated. Sites of roadworks and the additional loads resulting from these are not shown on these maps. However, since these road sections commonly are very short compared to the total driving distance, the resulting additional loads can be neglected. If for testing purposes a testing spectrum is used that is derived from the site of the roadworks, then either the transported equipment should
