This International Standard defines and describes the maximum material principle and specifies its application.
The use of the maximum material principle facilitates manufac-ture without disturbing the free assembly of parts where there is a mutual dependence of size and geometry.
NOTE — The envelope requirement (see 5.2.2) for a single feature may be indicated by the symbol (e) (see ISO 8015) or by reference to an appropriate national standard invoking this requirement.
