I have a question about note (A) in SB-171 Table 2 thickness tolerance.
Im concerned about note A When tolerances are specified all plus or all minus double the value given.

My material is .187 thick C61400 from a 48” wide piece.
Correct me if this is wrong
.187 thick C61400 is 25% greater than value given in table 2, so that makes it .015.
My question is Note A When tolerances are specified all plus or all minus double the value given.
Where would it be specified all plus or all minus, are the values in table 2 all plus, or all minus, where does note A apply?

Sorry Mike.

I don't have ASTM/ASME SB 171 available to look at... A P35 material, Aluminum Bronze D plate correct? Maybe someone else will chime in... ;)

Respectfully,
Henry
