19、c) BSIEN 15433-6:2007 (E) 4 Introduction This standard was originally prepared by working group NAVp-1.4, Requirements and Testing, of the German Standardization Institute (DIN). It is part of a complete normative concept to acquire and describe the loads acting on goods and influencing them during
20、transport, handling and storage. This standard becomes significant when related to the realisation of the European Directive on Packaging and Packaging Waste (Directive 94/62 EC, 20 December 1994). This directive specifies requirements on the avoidance or reduction of packaging waste, and requires t
21、hat the amount of packaging material is adjusted to the expected transportation load, in order to protect the transportation item adequately. However, this presumes some knowledge of the transportation loads occurring during shipment. At present, basic standards, based on scientifically confirmed va
22、lues, which can adequately describe and characterize the magnitudes of transportation loads, especially in the domain of dynamic mechanical loads do not exist nationally or internationally. Reasons for this are mainly the absence of published data, insufficient description of the measurements or res
23、trictions on the dissemination of this information. This standard will enable the measurement and analysis of dynamic mechanical transportation loads, thus enabling the achievement of standardized and adequately documented load values. This series of standards consists of the following parts: Part 1
24、: General requirements; Part 2: Data acquisition and general requirements for measuring equipment; Part 3: Data validity check and data editing for evaluation; Part 4: Data evaluation; Part 5: Derivation of Test Specifications; Part 6: Automatic recording systems for measuring randomly occurring sho
25、ck during monitoring of transports. This standard defines requirements that should be observed when automatic recording systems are being used for the purpose of a transportation survey. In this, it deviates from the characteristics of the other parts of the series, as in this case the prime concern
26、 is not the need for scientifically based and generally applicable data, which are to be used for standardization purposes, but to assist users “shock recorders“. Such automatic and computer-based recording systems have gone through remarkable developments, particularly in relation to their storage
27、capacity and analysis capability. This, together with falling prices, has meant they are increasingly used for surveying specific transportations, especially inside packing. In general they do not reach the efficiency of a measuring chain such as used for test drives, especially in view of the stora
28、ge capacity needed to measure unfiltered dynamic data during transportation. Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 28/04/2008 04:03, Uncontrolled Copy, (c) BSIEN 15433-6:2007 (E) 5 1 Scope This standard specifies the technical and functional properties of automatic recording equipme
29、nt used to determine randomly appearing shocks during transportation. Such automatic recording equipment can be used to: determine mechanical shock loads on individual transportations; monitor the transportation means to observe the limits of the shock parameters; determine the shock loads on the tr
30、ansported item. This standard defines the sensors to be attached to the device, and specifies the minimum requirements for the parameters to be adjusted. It also defines the minimum requirements for the data analysis, as well as the data presentation. This standard covers the complete recording equi
31、pment, including its accelerometers and the data analysis in an external data processing unit. The accelerometers can be integrated into the device or separately mounted from it (external sensors). This standard also applies to the routine monitoring of individual transportations 2 Normative referen
