Basic Information
Scope
This document presents the dynamic data obtained during the transportation of electronic equipment by rail vehicles, with the aim of generating an environmental description from all available data and comparing it with IEC 60721. For each identified data source, the data quality has been evaluated and its consistency checked. The data quality check and classification of various data sources were performed in accordance with the provisions of IEC/TR 62131-1. This document primarily involves data extracted from multiple different sources, the quality and validity of which have a certain degree of credibility. Some data whose quality and validity cannot be verified in practice are also presented in this document to facilitate the verification of data from other sources. Such data are clearly marked when used in subsequent chapters. This document involves vibration and impact data from three different measurement tasks: one concerning the UK railway system, and two concerning the US railway system. Although one of them involves a multimodal transportation system that is less widely used worldwide, the data from this system were still included to verify the data from other sources. The vast majority of the railway measurement data presented come from the US, with the remainder from Western Europe. Some data sources indicate that they contain data from certain older vehicles, and it is not possible to trace the sources of railway data that were referenced during the formulation of the IEC 60721 severity rating.
