  1. Romania – Republic of SerbiaIPA Cross-border Cooperation Programme State of the art and trends of European and international standardization in soldering and brazing Timișoara 2013-07-19

  3. Standardization 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)

  4. Aims of standardization

  5. Levels of standardization Space of standardization • Metalurgy • Mechanics • Electrotechnics/electronics • Transport • Construction • Agriculture • Chemicals • IT • General • etc. • International • Regional • National • Professional • Company Fields/subjects of standardization Standardization aspects • Terminology • Types of products, classification • Requirements • Quality levels • Testing • etc.

  6. Welding and allied processes base manufacturing processes in important industrial sectors; special processes in the quality management language; traditional standardization field.

  7. Business management concept according to ISO 9001:2008 Continuous improvement of QMS Strategical level Customer requirements Detail level Strategical level Customer satisfaction Detail level Management Resources Measurement Analysis Improvement Product realization Product

  8. Main actors of standardization & related activities in welding and allied 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

  9. 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 60s years; - growth of ISO/TC 44 activityin the 70sand 80s 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.

  10. Systemic approach 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.
