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

ISO 10303-47:2018-11 specifies the integrated resource constructs for Shape variation tolerances.

The following are within the scope of ISO 10303-47:2018-11:

• 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.
