DIN CWA 16633 DIN SPEC 91298:2013-09

The objective of the CWA is to elaborate a standard framework for the results of the IRIS Project, while it is recognized that there cannot be one extensive methodology fit for all specific industries. This framework covers methodologies for lifecycle management of constructed infrastructure. In order to meet the infrastructure owner's governing requirements regarding safety, operability and durability, the present CWA addresses the following major aspects: 1) The determination/estimation of the design life of new structures 2) The determination/estimation of the residual life of existing structures 3) Assessment criteria whether the real degradation process - determined by proper technologies - corresponds with the assumed and applied life cycle model, in order to take corrective measures in cases of accelerated ageing 4) Maintenance instructions to ensure the intended service life
