The CIS and CENELEC signed an agreement on the “joint programming of new works and parallel votes”, the CENELEC Guide 13, better known as the “Frankfurt Agreement” (the first agreement was signed in 1991, known as the “Lugano Agreement”, then replaced in 1996 by the “Dresden Agreement”, until it was revised in 2016 as the “Frankfurt Agreement”). The Frankfurt Agreement concerns the adoption of international standards as European standards. Other services, i.e. technical specifications and technical reports, are not part of the agreement. CENELEC maintains close collaboration with its international counterpart, the International Electrotechnical Commission (IEC). In order to facilitate the search for consensus between European and international standardization activities in the electricity sector, CENELEC and the IEC formalized the framework of their cooperation by signing in 1996 an “agreement on joint planning of new work and parallel consultations”, known as the Dresden Agreement. CEN and CENELEC sometimes sign cooperation agreements with the national standardisation bodies of some of Europe`s important trading partners. These agreements first facilitate the exchange of information and encourage harmonization within the framework of ISO and IEC and may include technical cooperation as a complementary means of promoting harmonization. In order to avoid duplication between standardisation at international and European level, to the benefit of standard contributors and users, as well as to improve the effectiveness of standardisation at European and international level, CEN and CENELEC have signed agreements with their respective international partners, the International Organisation for Standardisation (ISO) and the International Electrotechnical Commission (IEC). define the rules of cooperation.
The Vienna Agreement, signed in 1991 between CEN and ISO, recognises the primacy of international standards and aims to ensure that standards are recognised simultaneously at international and European level by improving the exchange of information and mutual representation at meetings. Either CEN or ISO take the lead in the development of a new standard and the relevant documents must be submitted for simultaneous approval. ISO members can thus influence the content of the CEN standard and vice versa. Around 31% of CEN standards are developed under the Vienna Agreement. The main objective of CENELEC-IEC cooperation is to avoid duplication and reduce the time it take to develop standards. Therefore, new draft electrical standards are planned jointly between CENELEC and IEC and most are, if possible, implemented internationally. This means that CENELEC will first offer a New Work Item (NWI) to its international counterpart.. .
