Foreword
This document (EN 50317:2012) has been prepared by CLC/SC 9XC, "Electric supply and earthing systems
for public transport equipment and ancillary apparatus (Fixed installations)", of CLC/TC 9X, "Electrical and
electronic applications for railways".
The following dates are fixed:

• latest date by which this document has to be
implemented at national level by publication of (dop) 2012-12-26
an identical national standard or by
endorsement
• latest date by which the national standards
conflicting with this document have to (dow) 2014-12-26
be withdrawn
This document supersedes EN 50317:2002 + A1:2004 + A2:2007.
EN 50317:2002 + A1:2004 + A2:2007:

- new definitions for “cord force”, “mean contact force” and “total mean uplift force” (Clause 3);
- updated abbreviation lists (Clause 4);
- requirements for examination of total mean uplift force and aerodynamic portions (new Clause 6);
- a clear relation between the different portions of contact force (7.1);
- limits for aerodynamic influences of the force measurement system (7.2);
- the aerodynamic correction for measured contact forces (7.4);
- corrections and elaborations for calibration of force measurement (7.5);
- adjustment of filter requirements (7.6);
- adjustment of accuracy requirements for measurement of displacements (Clause 8);
- updated requirements for measurement of arcing (Clause 9).
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CENELEC [and/or CEN] shall not be held responsible for identifying any or all such patent rights.
This document has been prepared under a mandate given to CENELEC by the European Commission and
the European Free Trade Association, and supports essential requirements of EU Directive(s).

this document.
1 Scope
This European Standard specifies the functional requirements for output and accuracy of measurements of
the dynamic interaction between pantograph and overhead contact line.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated references,
the latest edition of the referenced document (including any amendments) applies.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
collector head / pantograph head
pantograph equipment comprising the contact strips and their mountings
3.2
contact point
point of mechanical contact between a contact strip and a contact wire
3.3
working area of pantograph head
lateral and vertical range of possible contact points on the contact strips during normal operation
3.4
contact force
vertical force applied by the pantograph to the overhead contact line
Note 1 to entry: The contact force is the sum of the forces of all contact points
3.5
mean contact force F
m
statistical mean value of the contact force

Note 1 to entry: F is formed by the static and aerodynamic components of the pantograph contact force
m
3.6
static contact force
vertical force exerted upward by the collector head on the overhead contact line at standstill
3.7
standard deviation of contact force σ
square root of the sum of the square errors divided by the number of output values minus 1
3.8
aerodynamic force
additional vertical force applied by the pantograph as a result of air flow around the pantograph assembly.
The aerodynamic force depends upon speed

m
3.11
cord force
measured force in a cord restraining a contact strip at a defined height
3.12
total mean uplift force
vertical force measured at the pantograph head, the latter not touching the contact line. It is equal to the sum
of static contact force and the aerodynamic force caused by the air at the considered speed for a given
height of contact points

standard conditions
3.16
pantograph current
current that flows through the pantograph
3.17

sensitivity curve
relationship between the power density of the arc in µW/cm² and the response of the detector in volts
within the spectral range of interest
3.19
nominal current
current that flows through one pantograph for nominal power of train
