NEQA,
It is common for a specification(s) to use a general description but I am surprised that a procedure does not describe the inspection in more detail. At any rate, we always request clarification. On pressure vessels for example, inspection of the process side of all pressure boundary welds is sometimes required, in which case the ID face of the flange welds undergo examination. Sometimes all internal attachment welds are also included in the scope of work. Some of our customers do require final MT or PT on “all welds”, and that is what they get. By the way, Spectronics does make a black light stick that is about
1 ¼” in diameter if you are considering going with a fluorescent penetrant.
