7. At the beginning, it had been planned to collect, within Commission II, information about the welding of boilers and pressure vessels, Mr. KERKHOF (Netherlands) being made responsible for preparing proposals for international specifications on this subject. In 1950, a working group was formed within Commission II ; but, on the establishment of Commission XV in 195 l, the field of activity of this working group was transferred to that Commission (Fundamentals of Design and Fabrication for \iVelding). Since then, the work has been carried out by an autonomous Commission, Commission XI (Pressure Vessels, Boilers and Pipelines). 8. At the Oxford meeting in 1951, Commission II set up a Sub-Commission <( deep penetration welding ll, the first Chairman of which was Mr. D. LAGRANGE (Belgium); in 1956 l\fr. E.
