The corresponding parts of the text in the European Standard are marked by reference to the nationally determined parameters (NDP). NA 2.1, General, contains a list of these parts of the text. The nationally specified parameters are found in NA 2.2. Furthermore, this National Annex contains non-contradictory complementary information (NCI) with regards to EN 1995-1-1 which are permitted according to Guidance Paper L "Application and use of Eurocodes" of the European Commission. The numbering of the nationally specified parameters and the non-contradictory complementary information is associated with those contained in DIN EN 1995-1-1:2010-12 and is additionally marked with a prefixed "NA".
