Over deze norm
IEC/TR 62131-4, which is a technical report, reviews the available dynamic data relating to electrotechnical equipment transported by road 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 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 categorize the various data sources is set out in IEC/TR 62131-1. This technical report primarily addresses data extracted from a number of different sources for which reasonable confidence exists as to the quality and validity. The report also presents data for which the quality and validity cannot realistically be reviewed. These data are included to facilitate validation of information from other sources. The report clearly indicates when utilizing information in this latter category. This technical report addresses data from a number of data gathering exercises. The quantity and quality of data in these exercises varies considerably as does the range of road (and test track) conditions covered. The vast majority of the road conditions are from Western Europe. It is believed that one of the data sources considered is that used to set the current IEC 60721 severities. However, review of that data indicates the inclusion of some quite old vehicles. Relatively little of the data reviewed were made available in electronic form. To permit comparison to be made in this assessment, a quantity of the original (non-electronic) data have been manually digitized.
