本欧洲标准适用于设计用于连续感测铁路车辆负载的自动变量负载感测装置，并提供可由继电阀使用的信号，用于自动变更制动器应用中的空气压力，从而调节制动力从而达到所需的制动性能。 本欧洲标准规定了自动变量负载检测设备的设计，尺寸，制造和测试的要求

This European Standard applies to automatic variable load sensing devices designed to continuously sense the load of a railway vehicle and provide a signal that can be used by a relay valve for the automatic variation of the air pressure used for brake application, thereby adjusting the brake force accordingly to achieve the required brake performance. This European Standard specifies the requirements for the design, dimensions, manufacture and testing of automatic variable load sensing devices.
