Legal access to EN and ISO standards starts with two checks: whether the source is entitled to supply the document, and whether its licence covers your intended use. Buying a PDF is one route, but authorised institutional subscriptions and official free-access services may also be available. A free document is not automatically an unauthorised copy.
Four routes to access standards
1. Buy from a standards body
For ISO publications, start with the ISO Store or your national ISO member. ISO’s purchasing guidance explains these options. For European Standards, CEN and CENELEC themselves do not sell the documents: their national members and affiliates supply them.
Search by the complete reference and edition year. Check the language, national adoption and any amendments or annexes you need. A catalogue description helps you identify a document; it does not replace its full requirements.
2. Use an authorised external catalogue
Distributors can provide a convenient way to find documents from different publishers. Check the supplier’s identity, distribution arrangements and terms before ordering. Genorma is an external catalogue; purchases and customer support take place with that provider.
Review Genorma’s current terms and the selected product’s access option. Downloadable PDFs and online reading access have different permissions. Confirm account requirements, delivery arrangements, access deadlines and refund conditions instead of assuming instant delivery or permanent access.
3. Check licensed institutional access
Before purchasing, ask your employer, university or library whether an existing licence covers the document and your use. Access may depend on your affiliation, location or the number of permitted users. Institutional access does not automatically permit redistribution to clients or colleagues.
For students and researchers, CEN and CENELEC recommend contacting the national standards body to ask about facilitated access. Availability and conditions vary; do not assume every institution supplies every standard.
4. Look for official free or read-only access
Selected ISO/IEC documents are available at no charge through the official webstores, as explained in ISO’s publicly available standards notice. ISO also offers previews of parts of standards through its Online Browsing Platform. Check whether you are viewing the full document or only introductory sections.
The European Commission’s access page links to free national reading platforms for disclosed CEN/CENELEC harmonised standards. It currently directs requests for harmonised standards based on ISO or IEC documents through the individual access-request procedure. Free reading does not automatically include permission to download, reproduce or redistribute the text.
Check the document, edition and licence
Before paying or relying on a document, confirm:
- Identity: the complete number, title, edition, language and relevant national adoption.
- Completeness: whether amendments, corrections and any necessary national annexes are included or supplied separately.
- Status: whether it is published, a draft, withdrawn or superseded, and what your project requires.
- Permissions: who may use it, on which devices or sites, and whether printing, shared storage or network access is allowed.
- Access conditions: download deadlines, subscription duration, update coverage and the provider’s support arrangements.
ISO’s licence agreement and CEN/CENELEC’s copyright guidance explain why access and reproduction rights must be checked. Retain the invoice, licence and document reference for your records.
Publication dates and compliance are different checks
Standards are reviewed periodically; review does not necessarily produce a new edition. ISO’s maintenance rules allow a standard to be confirmed, revised, amended or withdrawn. There is no general rule that every standard changes annually.
For CE marking, consult the Commission’s harmonised-standard references for the relevant legislation, including restrictions and withdrawal dates. Do not assume the newest publication is already the cited edition. An older edition’s suitability depends on the applicable requirements and transition arrangements. Purchasing a standard alone does not demonstrate conformity.
Frequently asked questions
Can I use a free PDF?
Check its provenance, completeness, edition and permitted uses. Official no-charge documents exist, but an unexplained download from a forum is not evidence of authorised distribution.
Can I email a purchased standard to my team?
Only if the licence permits it. Ask the supplier about additional users or network access before distributing copies. Use our company standards-sharing guide to compare individual, multi-user and network access and prepare questions for the supplier.
Will a subscription save money?
Compare the actual documents, users, renewal costs and update coverage you need. No fixed number of standards guarantees a saving.
