This guide helps procurement teams, fabricators and project managers decide whether Part 2 belongs in their document set and what to clarify before ordering.
Which edition should you buy?
The catalogue edition checked on 7 October 2026 is EN 1090-2:2018+A1:2024. Genorma lists it as published; BSI lists its corresponding British adoption as current. Keep the amendment suffix in your purchase order: “EN 1090-2:2018” alone does not identify the same amended publication. Check the Genorma record and BSI catalogue.
If a contract names an older edition, ask the specifier to resolve that reference before replacing it. A newer catalogue record does not silently amend an existing contract. Record both the edition purchased and the edition the project has agreed to use.
Where Part 2 fits in the EN 1090 series
Part 2 concerns execution of structural steelwork, including relevant steel components in composite steel and concrete structures. Design and execution remain separate decisions: the public scope refers to the relevant EN 1993 and EN 1994 design standards. It also distinguishes reinforcing steel welded to structural steel from reinforcing steel used for reinforced concrete applications. Source: published scope.
| Document | Main question for the buyer |
|---|---|
| EN 1090-1 | Does the structural component fall within this conformity-assessment route? |
| EN 1090-2 | Which execution requirements apply to the structural steelwork? |
| EN 1090-3 | Is part of the package structural aluminium instead of steel? |
| EN 1090-4 | Are cold-formed structural steel elements for roof, ceiling, floor or wall applications within its scope? |
| Relevant Eurocode parts | Which design basis is specified, and who supplies the execution information? |
The cold-formed boundary deserves particular attention. BSI lists EN 1090-4:2018 for those applications. Do not select Part 2 solely because the material is steel.
Turn the purchase into a usable project brief
Before buying, write down what the team needs the standard to help deliver. The following is a procurement worksheet, not a substitute for its technical requirements.
- Identify the package. List component names, drawing revisions, material specifications and whether the order includes fabrication, delivery, site assembly or all three.
- Confirm the execution specification. Ask the responsible designer or specifier to identify the execution class and project-specific information. Do not select a class from price, building size or a supplier’s usual practice.
- Map the production interfaces. Separate welded assemblies, mechanically joined items, outsourced processes and work completed on site. Assign a person to resolve gaps between subcontractors.
- Agree the handover evidence. Ask which material records, welding records, inspection results and dimensional records the project needs, who provides them, and how they relate to the delivered components.
- Control changes. State who reviews a substituted material, revised connection or changed surface treatment before production continues.
These questions follow the principal subject areas described in the BSI overview: materials, joining, fabrication, surface treatment, tolerances and inspection. The licensed document supplies the applicable requirements and acceptance criteria.
Make the evidence list specific enough to reconcile with the order. A folder called “EN 1090 certificates” is difficult to review if its documents identify different factories, products or drawing revisions. A short index connecting each record to the component package is more useful than a large unexplained upload.
A fictional procurement decision
A maintenance contractor orders a welded steel access platform and a set of cold-formed roof purlins. The quotation describes both as “EN 1090 compliant” but gives no part references.
The buyer separates the two packages. The platform’s fabrication planning points towards Part 2. The purlins trigger a Part 4 scope check. The designer confirms the project execution information, while the supplier identifies the documents covering each product and manufacturing location. Any construction-product conformity assessment is reviewed separately.
The resulting purchase brief names the relevant publications and assigns responsibility for unresolved scope questions. It does not declare either package compliant merely because the buyer has bought a standard. This example is fictional and illustrates document selection, not a technical assessment.
What does this mean for CE marking?
Buying or applying Part 2 does not, by itself, establish a CE-marking route for every steel item. Check the product scope, relevant conformity-assessment standard and applicable construction-product framework. The Commission explains that product families move through the revised CPR framework individually, with transitional arrangements. Source: Commission CPR revision guidance.
Order the right document and access
Confirm the full reference, language and format. Ask the seller about licence coverage if several people need access; do not assume one PDF covers a shared project folder. Genorma’s terms describe document-use conditions.
The seller confirms the available options, licence and final checkout price.
Frequently asked questions
Is EN 1090-2 the same as EN 1090-1?
No. Part 2 addresses steel execution. Part 1 addresses conformity assessment of structural components. Decide which documents apply to the product and project rather than treating the part numbers as interchangeable.
Will the standard choose the execution class for my project?
Do not use a purchasing guide to make that selection. Obtain the project’s specified class and supporting execution information from the responsible competent professional, then use the appropriate licensed documents.
Is a supplier certificate enough to approve the order?
Review its scope, validity and connection to the actual supplier and package. It does not explain every material substitution, drawing change or project-specific requirement.
