This document gives the rules of definition and interpretation of general specifications defined according to ISO 8015 (general tolerancing) applicable on the whole workpiece.

The general specifications can be applied to integral surfaces only, i.e. integral lines are excluded.

The general geometrical and dimensional specifications defined in this document applies to the following:

— for dimensional specifications:

  — for features of size:

    — linear size (±) (according to ISO 14405-1);

    — angular size (±)(according to ISO 14405-3);

— for geometrical specifications:

  — for integral features:

    — geometrical specifications with the characteristic surface profile (⌓).

This document defines the maximum material requirement, the least material requirement and the reciprocity requirement. These requirements can only be applied to linear features of size of cylindrical type or opposed planar type.

These requirements are often used to control specific functions of workpieces where size and geometry are interdependent, e.g. to fulfil the functions "assembly of parts" (for maximum material requirement) or "minimum wall thickness" (for least material requirement). However, the maximum material requirement and least material requirement can also be used to fulfil other functional design requirements.
