ISO 10303-47:2025

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.
