该欧洲标准适用于空载转换装置，设计用于自动检测铁路车辆的负载何时达到定义值（转换质量），其表示车辆被归类为“加载”的点，从而要求制动力相应调整，以达到所需的制动性能。该欧洲标准还包括手动空载切换装置和相关联的切换板。 本欧洲标准规定了空载切换装置的设计，尺寸，制造和试验的要求

This European Standard is applicable to empty-loaded changeover devices designed to automatically sense when the load of a railway vehicle reaches a defined value (changeover mass), which represents the point at which the vehicle is classed as “loaded” and thereby requires the brake force to be adjusted accordingly to achieve the required brake performance. This European Standard also covers manually operated empty-loaded changeover devices and the associated changeover plates. This European Standard specifies the requirements for the design, dimensions, manufacture and testing of empty-loaded changeover devices.
