aPermissible variations in length apply also to Universal Mill plates up to 12 in. in width for thicknesses over 2 to 21⁄2 in., incl. except for alloy steels up to 23⁄4 in. thick.


Notes: Permissible variations under specified width and length, 1/4 in.

Table applies to all steels listed in ASTM A6.
