IEC/TR 62131-3:2011（E）审查了与轨道车辆运输的电工设备有关的可用动态数据。目的是从所有可用数据中生成环境描述，并与IEC 60721中规定的环境描述进行比较。对于每一个确定的来源，都会对数据的质量进行审查，并检查其自身的一致性。IEC/TR 62131中规定了进行数据质量检查以及对各种数据源进行本质分类的过程- 1.

IEC/TR 62131-3:2011(E) 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. 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.
