EN 1090

EN 1090

The NEN-EN 1090 is part of a series of standards that have been created to meet the Construction Products Regulations (CPR). The EN 1090 standard has implications for companies involved with the manufacturing of steel constructions. What requirements a company must meet depends on the role of the company in the supply chain.

For example, for manufacturers of steel pipes it is a hard requirement that they are Factory Production Control (FPC) certified by a recognized organization. Furthermore, a manufacturer must be able to provide a Declaration of Performance (DoP). A DoP provides information about the properties of the product, the conformity of the type of steel and its performance. This statement does not need to be sent with each delivery. It is sufficient if the manufacturer provides a DoP for each standard / quality combination.

Contractors or steel construction companies must ensure that the products used are traceable in accordance with EN 1090-2 section 5.2. For execution class 2, 3 and 4, products with a yield strength of 355N / mm² or higher must have a 3.1 inspection certificate. Products for the execution classes 3 and 4 must be fully traceable in all stages. From receiving, processing to delivery.
