Isn't it something like MIL-T-31000, I tried to find it in the ASME specs a while ago and had trouble, I'd appreciated if anyone can give the ref.
One thing that occasionally gets missed on Class 1 is that the changes must be both forward and backward compatible. i.e. not only must the new rev replace the old but if necessary the old rev can replace the new.

Sorry, I should have noted it was non-standard, but based on a standard. I'm trying to find the mother document.
