Article 14
Technical features and standardisation 1. In implementing the provisions of this Directive, Member States shall ensure, subject to paragraphs 2 and 3, that no mandatory requirements for specific technical features are imposed on terminal or other electronic communication equipment which could impede the placing of equipment on the market and the free circulation of such equipment in and between Member States. 2. Where provisions of this Directive can be implemented only by requiring specific technical features in electronic communications networks, Member States shall inform the Commission in accordance with the procedure provided for by Directive 98/34/EC of the European Parliament and of the Council of 22 June 1998 laying down a procedure for the provision of information in the field of technical standards and regulations and of rules on information society services(9). 3.
