Preproduction tests, including life tests, were successfully performed and a report prepared. A second aging and test set was modified for use by the 7890. A second set of brazing fixtures was obtained. Conclusions The tubes reproduced the original test data when formal preproduction tests were made. No trends were observed in the required end point test readings during the life tests. A continuous input water cooling system for the aging and test gear is more satisfactory than a recirculatory system. Author
