What is the EN 1090-1:2009/A1:2011?
EN 1090-1:2009/A1:2011 is a European standard covering the manufacture of steel and aluminium structures. The standard applies to the manufacture of load-bearing structures, such as, for example, steel structures for buildings and bridges, and it sets requirements for the quality of production processes.
The standard aims to ensure a harmonised way of working within Europe, so that steel and aluminium structures meet the required quality standards and are safe. The standard is important for manufacturers marketing products that require CE marking. CE marking shows that the product complies with relevant European standards and legislation.
To conform to EN 1090-1:2009/A1:2011, manufacturers must meet certain requirements in terms of technical documentation, quality management and process control. The standard requires a manufacturer to have a certified quality assurance system, for example one corresponding to ISO 3834 (for welding), as well as product conformity assessments.
The manufacturer must carry out an assessment process before the production of each product and ensure that documents (such as technical files, inspection reports and test results) are available for verification. This is crucial for obtaining the CE mark. It also helps ensure the safety and quality of the structures produced.
