3、Tolrances de variation de forme c RECTIFICA TIF TECHNIQUE 1 Technical Corrigendum 1 to International Standard IS0 10303-47:1997 was prepared by Technical Committee ISO/TC 184, Industrial automation systems and integration, Subcommittee SC 4, Industrial data. Introduction This document corrects IS0 1
4、0303-47:1997, Product data representation and exchange - Part 47: Integrated generic resource: Shape variation tolerances. The corrected document supersedes IS0 10303-4 7: 199 7. The purpose of the modifications to the text of IS0 10303-47:1997 is to correct errors in the EXPRESS definitions likely
5、to cause compilation problems, to replace u WR that Mias overly restrictive, to replace the annex,for the computer-interpretable EXPRESS with a URL reference, and to replace the object identifier far the document and the applicable schema.
