Subj: Proposed Combination of B345 with B241 As part of a task group started in 2012, we have been asked to propose a combined standard encompassing B241 and B345. Basically, the approach is to roll B345 into B241. Both cover extruded seamless tube. This activity was started because of limited resources to review and update standards, especially those that show limited activity such as B345. At the last two meetings of Subcommittee B7.03, we have looked at the proposed first draft of such a combination. There have been no objections raised during these two reviews, though we realize that there are probably issues of clarity yet to be resolved. At the last meeting in Jacksonville, it was proposed and accepted to place the current revision on Subcommittee Ballot to seek comments. Accordingly, that draft is attached. Please include it on the January 2nd Ballot for B7.03.
