BS EN 15437 is a European standard on axle box condition monitoring that discusses interface and design requirements. BS EN 15437-1 is the first part of a multi-part series that outlines minimum characteristics for the interface between a trackside hot axle box detector (HABD) and rolling stock (RST) that comply with the European directives for interoperability to ensure that the minimum functional requirement of the interface is achieved.
Under BS EN 15437-1 the minimum requirements of the interface apply to:
Note 1: Interoperable rolling stock designed for speeds above 250km/h (class 1 high speed rolling stock) is mandated to have on-board equipment for axle box condition monitoring. The requirements for on-board equipment are described in part two of this standard which is currently under development.
Note 2: Interoperable rolling stock designed for speeds above 250km/h (class 1 high speed rolling stock) is outside the scope of BS EN 15437-1. However, if class 1 high-speed trains are required to be monitored by HABDs their target area should comply with the requirements specified in BS EN 15437-1, except where stated otherwise.
Note 3: The scope of BS EN 15437-1 of the standard does not include:
BS EN 15437-1 on the track side equipment and rolling stock axle box is useful for:
Failed axle bearings on rolling stock create a hazard to the safe operation of the railway. If an axle bearing fails whilst rolling stock is in-service there is the potential for a catastrophic event. A catastrophic event may result in fatalities, severe damage to rolling stock and the infrastructure, and a risk that rolling stock may derail or fire may develop. An indication that a bearing is about to fail is a rise in the heat generated by the bearing. Bearings that are
about to fail may therefore be detected by monitoring their temperature to identify an unacceptable rise. One way of managing the risk is by installing a trackside Hot Axle Box
Detectors (HABDs) is to monitor the in-service temperature of rolling stock axle boxes.
BS EN 15437-1 guideline assists you with requirements on target zone, dimensions of the target area, the position of the centre of the target area in the XY plane, visibility requirements for the target area, prohibitive zone, dimensions of the prohibitive zone, the position of the centre of the prohibitive zone in the XY plane, electromagnetic interference emissions, design drawings, protective finish and much more.
BS EN 15437-1 also guides on temperature measuring zone, installation requirements, system requirements, functions, temperature alarms, general requirements and minimum requirements for the interface between a trackside HABD and rolling stock, to ensure that the system works.
With obedience and compliance to BS EN 15437-1, you can standardise the track side equipment and rolling stock axle box. Additionally, ensure that the minimum functional requirement of the interface is achieved.
