In the above example m and k has defined the tolerance. Nominal width 600mm. Geometrical tolerances for features without individual tolerance indications. The tolerances on thickness shall be given in table 1 and apply over the whole length.

2005 continuously hot rolled steel sheet products dimensional and shape tolerances. Sheet metal is manufactured and delivered from the processing mill rolled to the standard thickness that you specify which is now metric. This standard is designed to bring together tolerances for cold rolled narrow and wide strip. The sheet metal does however have a tolerance on the rolling thickness which needs to be taken into account when designing a tight fitting assembly especially as the sheet metal material gets thicker.

During the rolling process the rollers bow slightly which results in the sheets being thinner on the edges. 1989 general tolerances part 2. General tolerance iso 2768 does not specify where to use these tolerances. Tolerances to iso 9445 for cold rolled narrow and wide strip plate sheet and cut lengths general.
