There are a lot of ISO specs when it comes to GD&T, and this saves from having to list all of them.ĭoes this only cover ISO GD&T standards, or is it the wide range of ISO specs?īasically my question is in relation to the application of GD&T is knowing how to differentiate when you have to apply ISO 1101 or ASME Y14. It could reference a completely different ISO specification for something unrelated, and technically then ISO 1101, and a whole host of ISO specs are invoked. So it doesn't have to say interpret drawing per ISO 1101. ANSI/ASME YM (R) Line Conventions and Lettering This Standard establishes the line and lettering practices for use in the preparation of. This revision was approved as an ASME Standard on March 14, 1994, and as an American National Standardon January 5, 1995. ASME Y14.2 Line conventions and lettering ASME Y14.3 Multi-view and sectional view drawings ASME Y14.4 Pictorial drawings ASME Y14.5 Dimensioning and tolerancing ASME Y14.24 Types and applications of Engineering drawings ASME Y14.34 Associated lists ASME Y14.35 Drawing revisions ASME Y14.38 Abbreviations ASME Y14. ISO only requires one ISO specification to be listed on the drawing, and then ALL ISO specifications are invoked. ASME Y14.5 is a standard published by the American Society of Mechanical Engineers (ASME) to establish rules, symbols, definitions, requirements, defaults. They shouldbe sent to The American Society of Mechanical Engineers Attention: Secretary, Y14 Main Committee 345 East 47th Street New York, NY 10017.
Both standards require the drawing to state that it is to be interpreted per that particular standard.
