EU Declaration of Conformity requirements by product
The legislation behind a Declaration of Conformity depends on what the product is: whether it runs on mains voltage, contains a battery or a radio module, or falls under product-specific rules such as ecodesign. Each guide lists the EU legislation that typically applies, the harmonised standards manufacturers rely on, what the declaration must contain, and the mistakes we see most often.
