Section II-D lists only class one of the subject material in the allowables table. Vendors give me the impression that classes 2 & 3 are difficult if not impossible to find. I was wondering if anyone could shed any light? Are classes 2 & 3 dead? Or does Section II-D only list Class 1 because it has the lowest allowables of the bunch, and thus maintains the code's conservative nature?
