TC 24

Technical Commitee - Integrity of Railway Structures


Meeting hosted by DGZfP (German society for non-destructive testing)
Wittenberge, 24-25 September 2017

The next ESIS TC24 workshop "Integrity of Railway Structures" was held in Wittenberge/Germany, Monday 25. to Tuesday 26. of September 2017.

The workshop,organized by Thomas Heckel ( and Ronald Krull, has been organized by BAM (Federal institute for materials research) at DGZfP training facilities Wittenberge, Schillerplatz 3, 19322 Wittenberge/Germany.

The workshop has provided an opportunity for the axle community to meet up again and to discuss results of previous projects and, especially, from RAAI aiming at the determination of inspection intervals based on a fatigue crack growth and corrosion-fatigue assessment (see RAAI project).
