Where a Member State or the Commission considers that a harmonized standard does not fully meet the essential requirements of a directive, the matter will be brought to the attention of the committee set up by the Directive 98/34/EC (Committee on Technical Standards and Regulations). The Commission, taking into account the Committee's opinion, notifies the Member States whether or not the standard should be withdrawn from the list published in the Official Journal of the European Communities.

Many New Approach directives provide for a standing committee to assist the Commission, delivering its opinion on draft measures to implement the provisions of the relevant directive and examining matters relating to the implementation and practical application of the directive. Further, regular meetings to discuss technical implementation issues take place in working groups, which are composed of representatives appointed by Member States and interest groups (for example notified bodies, standards organizations, manufacturers, distributors, consumer organizations and trade unions), and chaired by the Commission.
