適用范圍：This part of ISO 10303 specifies the interpretation of the integrated resources to satisfy require-ments for the representation of the allowable deviation of physical characteristics of a product's shape according to ISO 1101. The following are within the scope of this part of ISO 10303: — tolerances as constraints on shape aspects of a product; — the specification of tolerances of the shape of a product; — the representation of geometrical tolerances; — the representation of tolerance values; — the specification of datums and datum references; — the identification of derived shape elements such as centre lines and intersections. The following are outside the scope of this part of ISO 10303: — the representation of plus-minus tolerances and limits and fits; — the definition of the fundamental principles, concepts, and terminology of tolerancing and dimensioning; — the mathematical definition of tolerances and datums; — the description of dimensioning or tolerancing practices; — the specification of dimensional inspection methods; — the synthesis and analysis of tolerances; — the tolerancing of product characteristics other than shape; — the presentation of tolerances on engineering drawings; — the representation of the product's shape; — the representation of dimensions. NOTE - This part of ISO 10303 provides the interpretation of the integrated resources in the area of product data indicated above, whereas the application of industrial requirements is a task to be fulfilled by application protocols (APs). Parts of ISO 10303 that make use of the elements defined in this part are strongly advised to check the ISO standards that deal with the application of tolerances available at the time of the development.
