标准范围

本文件适用于设计用于安装在铁路车辆和类似车辆上的弹性体机械部件，无论轨道类型和运行表面如何，这些车辆在带有永久导向系统的专用轨道上运行。弹性体机械零件的典型应用包括:-？车辆悬挂系统；-？设备安装系统；-？接头（例如阻尼器的端部安装件、橡胶支座、机械联轴器上使用的弹性体机械部件）；-？限制停车。这些部分可以是:-？完全由弹性体制成，独立运行或与其他弹性部件组合运行；-？由弹性体和其他材料组成，粘在一起或不粘在一起。本文件规定了橡胶和橡胶-金属零件要达到的特性，以及要进行验证的适用检验和试验方法。本文件不适用于:-？用于气动悬架弹簧的橡胶膜片；-？抛光和牵引装置弹簧的弹性部件；-？隔膜、波纹管和密封件；-？软管和管道；-？传动带。

This document applies to elastomer-mechanical parts designed to be fitted on railway vehicles and similar vehicles running on dedicated tracks with permanent guide systems, whatever the type of rail and the running surface.Typical applications of the elastomer-mechanical parts include:—    vehicle suspension systems;—    equipment mounting systems;—    joints (e.g. end-mountings of dampers, rubber-based bearings, elastomer-mechanical parts used on mechanical couplings);—    limit stops.These parts can be:—    made entirely of elastomer, operating on their own or in combination with other elastic parts;—    made up of elastomer and other materials, adherent together or not.This document specifies characteristics that rubber and rubber to metal parts are to achieve, together with applicable inspection and test methods to be carried out for verification.This document does not apply to:—    rubber diaphragms for pneumatic suspension springs;—    elastic parts of buffing and drawgear springs;—    diaphragms, bellows and seals;—    hoses and tubings;—    transmission belts.
