This document has been prepared by NA 005-08-07 AA "Aluminiumkonstruktionen unter vorwiegend ruhender Belastung (SpA CEN/TC 250/SC 9 + CEN/TC 135)" ("Aluminium structures under static loading (Mirror Committee of CEN/TC 250/SC 9 + CEN/TC 135"). This document constitutes the National Annex to DIN EN 1999-1-4:2010-05, "Eurocode 9: Design of aluminium structures - Part 1-4: Supplementary rules for trapezoidal sheeting". The European Standard EN 1999-1-4 allows national safety parameters to be specified for a number of points. These nationally determined parameters (NDP) cover alternative procedures, the provision of individual values, and the 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. In addition, the National Annex contains non-contradictory complementary information (NCI) on the application of DIN EN 1999-1-4:2010-05.
