Presumption of Conformity
Definition
Presumption of conformity is the legal effect by which a product that conforms to a harmonised standard, or parts of it, whose reference has been published in the Official Journal is presumed to comply with the requirements covered by that standard.
Expanded Explanation
The presumption is rebuttable and partial. It is rebuttable because an authority may still challenge compliance on evidence. It is partial because it extends only to the requirements the standard actually covers, so applying one harmonised standard rarely discharges every requirement that applies to a product.
Where no suitable harmonised standard exists, the Commission may adopt common specifications by implementing act, which produce the same presumption for the requirements they cover.
Nothing obliges a manufacturer to use a harmonised standard. The alternative is to demonstrate compliance directly, which is lawful but places the whole evidential burden on the technical documentation.
Why It Matters
Presumption of conformity is the practical reason standards work matters commercially. It converts a contested technical argument into a documented reference.
Legal and Regulatory Context
Regulation (EU) 2024/1781, Articles 40 and 41 on harmonised standards and common specifications, read with Regulation (EU) No 1025/2012.
Relationship to Adjacent Concepts
Presumption of conformity is the effect; harmonised standards and common specifications are the instruments that produce it.
Common Misconceptions
It shifts the starting position, not the outcome. A market surveillance authority may still find non-compliance on the evidence.
