Abstract

This report provides an evaluation of the ISO 10303 Part 47 draft with respect to ANSI and ISO tolerancing standards. We expect that the information contained in this report will contribute toward the completion and harmonization of Part 47. This document is the result of a comparison of the Part 47 draft with existing and developing U.S. and international dimensioning and tolerancing standards. Comparison results are summarized in tables in each section. The comparison of the Part 47 draft with other standards is made in basic tolerancing principles, size tolerance, datum and datum establishment, and geometric tolerances specific in standards. Recommendations for additions and modifications of Part 47 are at the end of each section. The objective is to have Part 47 completely cover the basic principles, concepts, and geometric tolerancing methods specified in ANSI and ISO standards.
