Conformity Assessment of the Execution of Steel and Aluminium Structures (CAESAS)

The Construction Products Regulation (CPR) requires structural steel and aluminium products to be CE marked to improve free trade across Europe. EN 1090 is a harmonised supporting standard that sets the requirements for conformity assessment of steel and aluminium structural components.

For a manufacturer to be able to CE mark their structural products, they require certification of their Factory Production Control (FPC) system by a specialist Conformity Assessment Body.

TWI CL is a Notified Body for the CPR (NB 2400) and performs assessment and certification of manufacturers in accordance with EN 1090-1 using its CAESAS Scheme.

FPC certification under CAESAS is supplemental to or inclusive of assessment and certification in accordance with ISO 3834 – Quality requirements for fusion welding of metallic materials.
