To comply with CE marking all fabricators must be able to demonstrate compliance with BS EN 1090 parts 1, 2 & 3: Execution of Steel structures and Aluminium structures.
- BS EN 1090-1: Requirements for conformity assessment of structural components explains that, since all structural steel is seen as safety critical, manufacturers must document and implement a Factory Production Control (FPC) system and have the system certified by a notified body.
- BS EN 1090-2: Technical requirements for steel structures, outlines what is required to ensure steel frames meet adequate levels of mechanical resistance, stability, serviceability and durability.
- BS EN 1090-3:2008. Execution of steel structures and aluminium structures. Technical requirements for aluminium structures
EN1090 Execution Classes (EXC): BS EN1090-2 introduces the concept of execution class. This enables specifiers to select the level of quality management suitable for the construction product.
To enable CE Marking of its fabricated steelwork, a steelwork contractor must declare and demonstrate its capability to produce a structure that will conform to a specified execution class.
