Bahnanwendungen - Oberbau - Prüfverfahren für Schienenbefestigungssysteme - Teil 4: Dauerschwingversuch
Diese Europäische Norm legt ein Laborprüfverfahren zur Aufbringung wiederkehrender Verformungszyklen fest, die Verformungen repräsentieren, wie sie vom Verkehr auf Eisenbahngleisen verursacht werden. Er wird zur Bewertung des Langzeitverhaltens (Performance) direkter Befestigungssysteme verwendet.
Die Verfahren sind für kraftschlüssig verbundene Schienen auf Gleisschwellen, Weichenschwellen und schotterloses Gleis sowie eingebettete Schienen anwendbar.
Dieses Prüfverfahren gilt für ein komplettes Schienenbefestigungssystem.

Železniške naprave - Zgornji ustroj - Preskušanje pritrdilnih sistemov - 4. del: Učinek ponavljajoče se obremenitve
Ta evropski standard določa laboratorijski preskusni postopek za uporabo ponavljajočih se ciklov premika, ki predstavljajo premike zgornjega ustroja železnice, ki jih povzroča promet. Uporablja se za oceno dolgoročnega delovanja neposrednih pritrdilnih sistemov.
Postopek se uporablja za tirnice, nameščene na prage, nosilno ogrodje in tire, ter vgrajene tirnice. Ta preskusni postopek se uporablja za celoten pritrdilni sestav.
