1 Scope
This Technical Report describes tests methods carried out to determine minimum routingdistances in order to avoid crosstalk of fast transients (bursts). The test results may beapplied to cable installations according to IEC 60092-352.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in IEC 60533 and thefollowing apply.
3.1
cable category
classification of a cable depending on the purpose or the kind of voltage (power supply, signal
transmission) the cable is intended for
NOTE Cable categories are shown in IEC 60533:1 999, Table C.1 (categories 2 and 4) or in VG 5375-3:2006,Table 2, categories 2 and 5 [4].
3.2
routing distance
intermediate free space between cables or bundle of cables of different, i. e. interfering and susceptible, cable categories
3.3
routing height
distance of cable or bundle of cables from reference ground (earth)
3.4
signal detector (SD)
electronic equipment used for detection and indication of disturbance
4 Principle
4.1 General
Electromagnetic compatibility (EMC) of electrical equipment or installations can be optimised by providing a defined distance between interfering and susceptible cable categories on cable routing. On the other hand the special situation aboard may call for such a distance to be as low as possible.
With the test described in this technical report, the sufficient separation distance between cables of different categories can be quantified. Definition numbers of the cable categories used in this technical report are stated in Table 1 .
