ISO 10303-47

Industrial automation systems and integration — Product data representation and exchange — Part 47: Integrated generic resource: Shape variation tolerances

Scope

ISO 10303-47 specifies the integrated resource constructs for Shape variation tolerances.
The following are within the scope of ISO 10303-47:

tolerances as constraints on the shape characteristics of a product;
the specification of the tolerances on a defined shape;
the representation of geometrical tolerances and plus-minus tolerances;
the representation of tolerance values;
the representation of dimensions;
the assignment of size characteristics to a shape;
the assignment of location and orientation characteristics to a shape;
the specification of datums and datum systems that are established by referencing datums;
the identification of derived shape elements such as centre lines and intersections;
the structure for limit and fit systems for shapes.
