Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national
standards bodies (ISO member bodies). The work of preparing International Standards is nor-
mallycarriedout through ISOtechnical committees. Each memberbodyinterested ina subject
for which a technical committee has been established has the right to be represented on that
committee. International organizations, governmental and non-governmental, in liaison with
ISO, also take part inthe work. ISOcollaborates closely withthe InternationalElectrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
DraftInternationalStandardsadoptedbythetechnicalcommitteesarecirculatedtothemember
bodies for voting. Publication as an International Standard requires approval by at least 75%
of the member bodies casting a vote.
International Standard ISO 10303{519 was prepared by Technical Committee ISO/TC 184,
Industrial automation systems and integration, Subcommittee SC4, Industrial data.
This International Standard is organized as a series of parts, each published separately. The
partsofISO10303fallintooneofthefollowingseries: descriptionmethods,integratedresources,
application protocols, abstract test suites, implementation methods, and conformance testing.
The series are described in ISO 10303{1.

Introduction
ISO 10303 is an International Standard for the computer-interpretable representation and ex-
change of product data. The objective is to provide a neutral mechanism capable of describing
product data throughout the life cycle of a product independent from any particular system.
The nature of this description makes it suitable not only for neutral �le exchange, but also as a
basis for implementing and sharing product databases and archiving.
This International Standard is organized as a series of parts, each published separately. The
partsofISO10303fallintooneofthefollowingseries: descriptionmethods,integratedresources,
application interpreted constructs, application protocols, abstract test suites, implementation
methods, and conformance testing. The series are described in ISO 10303{1. This part of
ISO 10303 is a member of the application interpreted constructs series.
An applicationinterpretedconstruct (AIC) providesa logicalgroupingof interpretedconstructs
that supports a speci�c functionality for the usage of product data across multiple application
contexts. An interpreted construct is a common interpretation of the integrated resources that
supports shared information requirements among application protocols.
This document speci�es the application interpreted construct for the description of allowable
deviation of physical characteristics of a product’s shape according to ISO 1101:1999.

| tolerances as constraints on shape aspects of a product;
| the speci�cation of tolerances of the shape of a product;
| the representation of geometrical tolerances;
| the representation of tolerance values;
| the speci�cation of datums and datum references;
| the identi�cation of derived shape elements suchascentre lines and intersections.
The following are outside the scope of this part of ISO 10303:
| the representation of plus-minus tolerances and limits and �ts;
| the de�nition of the fundamental principles, concepts, and terminology of tolerancing and
dimensioning;
| the mathematical de�nition of tolerances and datums;
| the description of dimensioning or tolerancing practices;

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national

Draft International Standards adopted by the technical committees are circulated to the member

The following are within the scop e of this part of ISO10303:
|tolerances as constraints on shap e asp ects of a pro duct;
|the sp ecication of tolerances of the shap e of a pro duct;
|the representation of geometrical tolerances;

The following are outside the scop e of this part of ISO10303:
|the representation of plus-min us tolerances and limits and ts;
|the denition of the fundamental principles, concepts, and terminology of tolerancing and
dimensioning;
|the mathematical denition of tolerances and datums;
|the description of dimensioning or tolerancing practices;
|the sp ecication of dimensional insp ection metho ds;
|the synthesis and analysis of tolerances;
|the tolerancing of pro duct characteristics other than shap e;
|the presentation of tolerances on engineering drawings;
|the representation of the pro duct’s shap e;
|the representation of dimensions.
NOTE-This part of ISO10303pro vides the interpretation of the integrated resources in the area
of pro duct data indicated ab ove, whereas the application of industrial requiremen ts is a task to b e
fullled b y application proto cols (APs). Parts of ISO10303that mak e use of the elements dened in
