What it is
A harmonised standard is a European standard whose reference has been cited in the Official Journal under a specific piece of EU legislation. This Commission resource lists the harmonised standards and explains their legal effect. Until a standard is cited, even an excellent EN is, legally, a voluntary standard.
Why it matters for compliance
Applying a harmonised standard gives a presumption of conformity with the essential requirements it covers: an authority must treat the product as conforming to those requirements unless it shows otherwise. This is the simplest, most defensible route — and for many products it permits self-assessment without a notified body.
How to use it
- Find the harmonised standards cited for your legislation, and check the citation is current.
- Apply them, and document which essential requirements they cover.
- Demonstrate conformity for any requirements the standards do not cover by other means.
Good to know
The presumption is bounded and can lapse: it reaches only as far as the standard covers the requirements, and continuing to rely on a withdrawn version may leave a gap — so track citations over time.
