"This specification covers established metric manufacturing tolerances applicable to bars and rods of copper and copper alloys ordered to metric dimensions. These tolerances apply to all conditions@ unless otherwise noted. The term ""exclusive"" is used to apply only to the higher figure of a specified range. If the tolerance is expressed as a percentage of a specified dimension@ the tolerance so calculated shall be rounded to the nearest 0.02 mm to obtain the permissible tolerance. AMS 2221 is the inch/pound version of this MAM. "
