本文件规定了机车车辆可回收性和可回收率的计算方法。 本文件中定义的方法适用于新机车车辆的设计。然而，根据可用信息，它可以应用于其他现有机车车辆。如果可回收性或可回收性的计算适用于机车车辆中使用的单独零件和/或产品，且该零件和/或产品存在特定的计算标准或方法，则可适用该标准或方法（如相关）。 无论地理位置如何，该计算方法均适用。 该计算方法适用于车辆生命周期的任何阶段。计算出的可回收率和可回收率在交付机车车辆产品或设备时有效。 本计算方法不考虑回收行业的未来回收技术或预测趋势。 该计算方法考虑了四个主要的处理过程，即再利用、再循环、能量回收和处置（图1）。回收过程中的损失在处置阶段处理。能量回收阶段的残留物（主要是灰渣）和处置阶段焚烧过程的残留物最有可能被填埋。

This document specifies a calculation method of recyclability and recoverability rates for rolling stock. The method defined in this document applies to the design of new rolling stock. However, it can be applied to other existing rolling stock depending on available information. If calculation of recyclability or recoverability is applied to separate parts and/or products used in rolling stock and a specific calculation standard or method exists for the part and/or product, such standard or method can be applied, if relevant. This calculation method is applicable regardless of any geographical concern. This calculation method is applicable to any stage of life cycle of rolling stock. The calculated recyclability and recoverability rates are valid at the point of delivering the rolling stock products or equipment. Future recycling technologies or predicted trends with respect to the recycling industry are excluded from any consideration for this calculation method. This calculation method considers the four main treatment processes, which are reuse, recycling, energy recovery and disposal (Figure 1). Process losses of recycling are treated in the disposal stage. The residue substances of the energy recovery stage (mostly ash and slag) and the residue of the incineration process of the disposal stage are most likely landfilled.
