IIW History 1990-2015

von Hofe (Germany) as Chair of CEN/TC 121 signed an historic agreement between the three organisations for cooperation in international standards. In doing so, CEN and IIW transferred responsibility for many standardisation projects to ISO, establishing a mechanism for sharing documents in development and for the allocation of work to one of the three organisations. 40 At the 2006 Annual Assembly in Quebec, C-II proposed the initiative of transferring the responsibility for all filler metals as Route II drafts to ISO/TC 44/SC3 which was rejected by the SC-STAND, a decision upheld by IIW’s TMB which considered that each standard should be treated separately. 41 Ziegenfuss was also opposed to such a move since it represented another means of limiting IIW’s authority in the ISO standards arena. 42 Eventually, the responsibility for filler metals involving classification was transferred to ISO/TC 44/SC3 only where justified through SC-STAND, a condition that CEN/TC 121 was also in agreement with. 43 All other filler metals standards remained the responsibility of SC-STAND. The first Technical Report to be published by

IIW was ISO TR 22824 Welding Consumables – Prediction and measurement of Ferrite Number (FN) in specifications – A position statement of the experts of IIW Commission IX in 2004. C-III, on the other hand, was one of the largest producers of welding standards and over the period 1984-1998 had produced a total of 17 draft standards for approval. 44 In one of the significant initiatives regarding solid state welding standards, C-III, chaired by Prof. Kin-

Kin-ichi Matsuyama

ichi Matsuyama, developed the ISO 25239 international series of friction stir welding standards for welding of aluminium and aluminium alloys, starting in 2004 after friction stir welding became part of C-III activities. The work was allocated to a sub-commission of Commission III, SC 3B under the leadership of Mr David Bolser (USA) who had already done a considerable amount of the work required for AWS and through his association and work with Boeing in the development of friction stir welding standards. 45 Work progressed very quickly due to the depth of experience within SC 3B, including input from Mr David Nicholas and Dr Wayne Thomas of TWI, and the first draft of the five- part series was introduced at the Prague meeting in 2005. The first hurdle to be met was one of patent rights expressed by Japan, which tested the resourcefulness of Ziegenfuss as IIW Standards Officer in the progression of these standards through the respective procedures to the DIS and final draft international standard (FDIS) stages of balloting and voting. No formal procedures or policies had been developed through ISO to account for the consideration of
