At the end of Table 1A Ferrous Materials [which your stuff is] there are groups of endnotes:
General Notes (a) thru (f)
NOTES - General Requirements G1 thru G44
NOTES - Heat Treatment Requirements H thru H5
NOTES - Size Requirements S1 thru S9 and the set you need
NOTES - Time-Dependant Properties T1 thru T10
and the last set is NOTES - Welding Requirements W1 thru W15
there are probably more NOTES in some sections now, I'm working from a 2003 book
Lastly, to do ASME Code work, you have to own ASME Code Books. For Sect VIII Div-1 work, that is VIII Div-1 [of course], Sect IX, Sect II-A, -B, -C, and -D, and Sect V. Without those, you are guessing.
