I have two separate process documents (one is a revision of the other) which cite two standards (ANSI/IPC-S-815 and ANSI/J-STD-001) in reference to the same wave soldering process. I do not have a copy of S-815 available. I know that J-STD-001 superseded S-815 in 1992. I was wondering if anyone could explain what the actual difference was between these two standards.
