Tolerance specifications should take into
consideration the following items:

Linear Tolerances*

Dimensions	Normal	Premium
Up to 1/4"	± .005"	± .003"
Up to 1"	± .008"	± .005"
Up to 2"	± .010"	± .008"
Up to 3"	± .012"	± .010"
Up to 4"	± .013"	± .011"
Up to 5"	± .015"	± .013"
Up to 6"	± .016"	± .014"
Up to 7"	± .018"	± .016"
Up to 8"	± .020"	± .017"
Up to 9"	± .022"	± .018"

Maximum variation	± .025"

*An exception to the standard linear tolerance exists on some wall thicknesses. The tolerance must be a minimum of ± .010".

Flatness and straightness. Tolerances for flatness and straightness are .003" to .005" T.I.R per linear inch and depend on alloy and casting configuration
