VSR - Verifiche di Stabilita dei Recipienti
The VSR collection (Verifiche di Stabilita dei Recipienti - Stability Verification of Vessels) is an Italian technical standard issued by ISPESL (now INAIL) for the design and verification of pressure vessels.
This collection provides formulas and calculation methods for the structural verification of components subjected to internal and external pressure.
NextGen supports the following chapters of the VSR collection:
