Some 154 global standards make up the third and updated edition of the ISO handbook "Technical Drawings." The goal of ISO/TC 10, the technical committee that drafted most of the standards, is to enable a drawing to be interpreted correctly in any country, regardless of language differences. Among the handbook's contents are standards for dimensioning, tolerancing, microcopying, surface texture, graphical symbols, and drawing equipment. A separate section deals with mechanical engineering drawings. You can buy the handbook, which comes in two volumes, from any national member of ISO or from the ISO Central Secretariat at 1 rue de Varembe, CH-1211 Geneva 20.
