scope:

This document specifies a procedure for fatigue strength assessment of rail vehicle structures based on cumulative damage.

It is part of a series of standards that specifies procedures for strength assessments of structures of rail vehicles that are manufactured, operated and maintained according to standards valid for railway applications.

This document is applicable for variable amplitude load data with total number of cycles higher than 10 000 cycles.

An endurance limit approach is outside the scope of this document.

The assessment procedure of the series is restricted to ferrous materials and aluminium.

This document series does not define design load cases.

This document series is not applicable for corrosive conditions or elevated temperature operation in the creep range.

This series of standards is applicable to all kinds of rail vehicles; however it does not define in which cases a fatigue strength assessment using cumulative damage is to be applied.
