ČSN EN 13445-3

This part of the standard gives the rules to be used for design and calculation under internal and/or external pressure (as applicable), local loads and actions other than pressure. The rules provided are both design by formulae (DBF), design by analysis (DBA) and design by experiment (DBE). The part also sets the requirements for when fatigue analysis must be performed and the rules to be followed when this is the case.
