For the purpose of demonstrating compatibility between rolling stock and axle counters, this document defines the interference limits for axle counter detectors and evaluation methods to verify rolling stock emissions.
Wheel sensors and crossing loops are not covered by this document.
For wheel sensors and wheel detectors in other applications than axle counters but utilizing the same sensors on the rail and detection circuits, transient and continuous interference can be considered as equivalent to axle counter detectors or axle counter sensors.
This document gives recommended individual limits to be applied to establish compatibility between RST and all selected types of axle counter detectors, including several covered by national standards.
The list of selected types of axle counter detectors and their limits for compatibility are drawn on the basis of established performance criteria.
To ensure adequate operational availability, it is essential that the rolling stock complies with the defined limits; otherwise, the established availability of the valid output function of axle counter detectors could be compromised.
