European Standard EN 1996-1-1:2005 allows national safety parameters, referred to as Nationally Determined Parameters (NDPs), to be specified for a number of points. The NDPs cover alternative verification methods, the provision of individual values and the

8、selection of classes from designated classification systems. The relevant parts of the text are identified in the European Standard by references to the possibility of national choice and are listed in NA.2.1. This Amendment to the National Annex is an integral part of DIN EN 1996-1-1:2010-12. DIN E
