CEN/BSI has issued a document concerning the implications of revisions to Harmonised European Standards.

ATEX standards are cited as an example of the information regarding the changes that should be included in a revised harmonised standard – proposed to be carried over to PED harmonised standards.

The revision of harmonised European standards has an impact on the presumption of conformity of a product. When a harmonised EN standard is revised, the date of withdrawal of the previous edition is stated in the OJEU as the date of cessation of presumption of conformity. However is the certificate of Type Approval still valid?

The new provision of the New Legislative Framework (NLF) reinforces the responsibility of the manufacturer on assessing the impact of the modifications of the harmonised EN standard on the certificate of type approval.
