Standardization Common borders. Common solutions. Activity of establishing, with regard to actual or potential problems, provisions for common and repeated use, aimed at the achievement of the optimum degree of order in a given context NOTE 1 In particular, the activity consists of the processes of formulating, issuing and implementing standards. NOTE 2 Important benefits of standardization are improvement of the suitability of products, processes and services for their intended purposes, prevention of barriers to trade and facilitation of technological cooperation. EN 45020: 2006 (ISO/IEC GUIDE 2: 2004)
Aims of standardization Common borders. Common solutions. Variety control Fitness for purpose Safety Communication Aims of standardization Interchangeability Protection of the environment Product protection Compatibility

Main actors of standardization & related activities in welding and allied Common borders. Common solutions. processes • ISO/TC 44 – Welding and allied processes • ISO/TC 107/WG 1 - Metallic and other inorganic coatings – Thermal spraying • IIW/WG-STAND – International Institute of Welding • IEC/TC 26 – Electric welding (Equipment for electric welding) • CEN/TC 121 – Welding • CEN/TC 240 Thermal spraying and thermally sprayed coatings • CENELEC/TC 26 Electric welding (Equipment for electric welding) • EWF – European Welding Federation
Common borders. Common solutions. Main steps of the evolution at international & European level of the standardization in welding • - first ISO recommendations for standardization, based on IIW documents, in the 60 s years; • - growth of ISO/TC 44 activity in the 70 s and 80 s years, but not sufficient; • - development of a systematic European standardization in CEN/TC 121, promotion of quality assurance/management concept, cooperation with ISO/TC 44 on Vienna Agreement basis from 1991; • - evolution of European & international standardization with parallel standards; • - relocation of the weight centre in the international standardization, with European cooperation.
Systemic approach Common borders. Common solutions. Business plans of CEN/TC 121 and ISO/TC 44: - from the general aims of the standardization; - from the standardization aspects required by the operation of quality management systems specific in welded production.
