Lab testing of "unlisted" materials for use to B31.3
Lab testing of "unlisted" materials for use to B31.3
(OP)
Does anyone have any suggestions for where to start in gathering lab data for unlisted materials for use to B31.3?
I would like to use an unlisted material that is manufactured to a specification meeting the needed B31.3 requirements (heat treatment, composition, strength, ect.); however, this specificaiton is not listed in B31.3. Following the code, it appears this specification could be used provided the allowable stress is computed per paragraph 302.3. However, to calculate the allowable stress, I need elevated temperature data, which would need to come from a labratory experiment.
Does anyone who has gone through this process have any suggestions?
