GB/T 16656.47-2001 Industrial automation systems and integration--Product data representation and exchange--Part 47: Intergrated resources: Shape variation tolerances (English Version)
This International Standard specifies resource constructs for expressing product shapes and tolerances. The size expresses the size of the shape and the position of the identifiable part of the shape. Tolerances specify the allowable deviations that define the shape and dimensions of a product. The dimensional tolerance expressions given in this standard are applicable to two-dimensional and three-dimensional part geometric models.
