Technical developments, leading to higher performance, higher efficiency, lower pollutions
and greater reliability, and the constraints imposed by economy and the need for
' L4 e+ W; c& g6 Z$ R' }rationalization, greater cooperation with licensees and subcontractors, make it necessary
to have completely toleranced drawings suitable for the function, for manufacturing
and inspection.
“Completely toleranced” means that the geometries (form, size, orientation and location)
4 ^0 o* W* e6 |/ b4 Bof geometrical elements of the workpiece are completely defined and toleranced.
Nothing shall be left to the individual judgement of the manufacturer or inspector. Only

additional specifications laid down in the German Standards (DIN Standards). Possible
further developments in the field of geometrical tolerancing are also pointed out.
