The Eurocodes NDPs Database stores the Nationally Determined Parameters (NDPs) adopted in the countries of EU and EFTA applying the EN Eurocodes. The NDPs are those parameters that were left open in the Eurocodes for national choice, to be used for design of buildings and civil engineering works, in order to take into account country differences in geographical, geological or climatic conditions, and different requirements for safety levels in the Member States. The NDPs Database was created by DG JRC in the framework of Administrative Arrangements with DG GROW in view of implementing the concerned parts of the Commission Recommendation of 11 of December, 2003, on the implementation and use of Eurocodes, namely in notifying the Commission on the adopted NDPs. The NDPs Database constitutes the basis for the analysis of the NDPs required by the Commission Recommendation and for the definition of strategies tending to achieve further convergence and consequently aiming at facilitating the achievement of the European single Market for construction works and structural construction products. The Database has restricted and controlled access and it is administrated by DG JRC, Safety and Security of Buildings Unit. The dataset spatial coverage is the European Union plus Norway and Switzerland.

European Commission, Joint Research Centre (2026): Eurocodes Nationally Determined Parameters (NDPs) Database. [Dataset] doi: 10.2905/JRC.KAM1M3R PID: http://data.europa.eu/89h/jrc-eurocodes-ndps
EN EurocodesNationally Determined Parameters - NDPs
Access to the NDPs Database is allowed to the interested Commission Services (DG GROW, DG JRC); CEN TC250 Coordination Group, its 11 Sub-Committees (SC1-SC11) and two Horizontal Groups, and the Project Teams under Mandate M-515; the interested National Authorities; the National Standardization Bodies; possible others to be defined by the Commission.
This document provides description of the Eurocodes database for Nationally Determined Parameters (NDPs database), which was created in the frame of the Administrative Arrangement (AA) between the Enterprise and Industry Directorate General (DG ENTR) and the Joint Research Centre (JRC) regarding the support to the implementation, harmonization and further development of the Eurocodes.
The database contains information about the National Annexes to each Eurocode Part and the respective NDPs, their recommended values and the values chosen by the EU and EFTA Member States and the EU Candidate Countries. The classification of the NDPs aiming at simultaneous mirroring the functionality of the NDPs in the code and the data type needed for the definition of the database fields is presented.
The NDPs database will constitute the basis for the analysis of the NDPs and for the definition of strategies tending to achieve further convergence and consequently aiming at facilitating the achievement of the European single Market for construction works and structural construction products.
The conditions for access to the database, NDPs upload rules and the possibilities for data post-processing are overviewed. The user’s manuals regarding the upload of the NDPs and data post-processing are incorporated as annexes to the report.
