The EN 1090 standards are European standards that regulate the fabrication and assembly of steel and aluminium structures and are recognized by the Construction Products Regulation.“List of Harmonized Standards” , European Commission, 05.08.2011
EN 1090 comprises three parts:“EN 1090-1, -2”, Karlsruher Institut für Technologie (KIT), p. 2, 05-08-2011
EN 1090-1: Requirements for conformity assessment for structural components (CE-Marking) EN 1090-2: Technical requirements for the execution of steel structures EN 1090-3: Technical requirements for the execution of aluminium structures
EN 1090 replaced the nationally applicable regulations, e.g. in Germany DIN 18800-7 and DIN V 4113-3.EN 1090 defines execution class from 1 to 4 for structural steel and aluminum elements, While Execution class 1 is for simple support elements and execution class 4 is for complex structural element such as those used in steel bridges
