"Standard" Sheet Metal Tolerances?

"Standard" Sheet Metal Tolerances?

"Standard" Sheet Metal Tolerances?

(OP)
Is there such a beast?  Is there a more current version of ASTM-A-480-99b than 03/01/2002?

Our company has set standards for 10ga SST 304 of .145-.130, but we have changed vendors and they provide .147-.135  They claim conformance to the above specification.  I am aware that tolerances will vary depending on the mill.

I've checked eFunda, but they do not list tolerances, only nominal gages.  Any help welcome.

RE: "Standard" Sheet Metal Tolerances?

ASTM A 480/A 480M - 04 is the most recent revision of this standard.  Tolerances will depend on product form (sheet, strip, width, etc.) but for hot-rolled wide coils & cut lengths, the tolerance on thickness is + 0.012 in. [0.30 mm] for specified thickness of > 0.130 [3.30 mm] to 0.145 in. [3.68 mm] and 0.013 in. [0.34 mm] for specified thickness > 0.145 in. [3.68 mm] to 0.1875 in. [4.76 mm].
