Dimensional Standards – General 

A.      All sizes are given in outside dimensions EXCEPT outside fitting covers and Relay Case (also called TC Case) A & B dimensions.

 

B.      The basic A, B and C dimensions and tolerances apply at the point of tangency of the radius. Bow tolerances are additive to the measured A, B and C dimension.

 

C.      The normal result of the deep drawing process renders the closed end of the can and corner radius areas thicker than the side wall.

 

D.     Piercing and trim burrs will be maintained within the limits specified below.

 

E.      Deburring shall be considered a separate and additional operation when removal beyond the listed limits is required.
