Commission Decision of 28 July 2006 concerning the technical specification of interoperability relating to the subsystem ‘rolling stock — freight wagons’ of the trans-European conventional rail system (notified under document number C(2006) 3345) (Text with EEA relevance) (2006/861/EC) (repealed)

[F1 3. ROLLING STOCK REQUIREMENTS U.K.

This section contains the requirements for the rolling stock side of the HABD interface.

3.1. Target Zone U.K.

The target zone is an area on the underside surface of an axle box described by the intersection of the axle box with a virtual cuboid that has a horizontal cross sectional area given by the dimensions XTA and YTA using the rolling stock coordinates. The horizontal cross sectional area of the virtual cuboid is therefore congruent to the plan view area (that is in the XY plane) of the target zone, herein named the target area.

3.2. Target area U.K.

The target area is set in space relative to the axle dimensions, and defines an area in which a HABD can focus to monitor the temperature of an axle box. Figure 2 shows the position and minimum dimensions of the target area using rolling stock coordinates.

Dimensions and position of the target area (TA) in the XY plane (viewed from below)

3.3. Dimensions of the Target Area U.K.

Taking into account mechanical tolerances the target area shall:

• have a lateral width, WTA, greater than or equal to 50 mm;

• have a longitudinal length, LTA, greater than or equal to 100 mm.

3.4. Position of the Target Area in the XY plane U.K.

In the XY plane the centre of the target area shall be positioned at a lateral distance, YTA, relative to the centre of the axle (or centre of a pair of wheels at the same position), where 1 065 mm is less than or equal to YTA and YTA is less than or equal to 1 095 mm. In the longitudinal axis the centre of the target area shall be congruent with the centre line of the axle.

3.5. Visibility requirements for the Target Area U.K.

Rolling stock shall be designed with no obstruction between the target zone and the HABD that would impede or prevent the HABD from focusing within the target zone and thereby prevent a measurement of its thermal radiation.

Note

:

The design of the rolling stock axle box should aim to achieve a homogeneous temperature distribution within the target zone.]
