What is PD IEC/TR 62131-3 - Vibration and shock in rail vehicles about?
PD IEC/TR 62131-3 is a standard that covers vibration and shock in rail vehicles, enabling the minimisation of shock severities for sensitive electrotechnical equipment. PD IEC/TR 62131-3 reviews the available dynamic data relating to electrotechnical equipment transported by rail vehicles. The intent is that from all the available data an environmental description will be generated and compared to that set out in IEC 60721 . In PD IEC/TR 62131-3 , for each of the sources identified the quality of the data is reviewed and checked for self-consistency. The process used to undertake this check of data quality and that used to intrinsically categorise the various data sources are set out in IEC/TR 62131-1 . PD IEC/TR 62131-3 report primarily addresses data extracted from a number of different sources for which reasonable confidence exists as to their quality and validity. PD IEC/TR 62131-3 addresses vibration and shock data from three different measurement exercises, i.e. one on the UK rail system and two on the USA rail system. Although one of these relates to a multimodal system in limited use worldwide, data from it are included to facilitate the validation of information from other sources.
