NDS Supplement design values: nominal or actual dimensions?

[Ricyteach]

This is probably a dumb question but I don't often need to use the NDS so: today I was looking at the supplement for design values for a 2x6. All the tables reference 2" to 4" thickness, etc etc.

I do not see anywhere in the NDS or the NDS supplement where it states that these dimensions are nominal or actual dimensions. I am assuming that probably they are nominal and that all of these design values can be applied to 2-by (1.5" thick) dimensional lumber (when multiplied by all the appropriate coefficients of course), but I just want to make sure.

Are the design values in these tables meant to be applicable based on nominal dimensions, and therefore applicable to 2-by lumber?

They are nominal as you are thinking.

Thanks for confirming! Annoying this doesn't seem to actually be stated outright in the supplement that I could find.

See Footnote 1. LUMBER DIMENSIONS. It references Table 1A for the nominal & dry dressed sizes.
