Many of these parts have been manufactured, delivered, inspected, and used based on these non-GD&T drawings for decades, and they don't want to mess it up now. They are afraid that changes to drawings might give the opportunity to have vendors re-quote prices for the same parts because the drawing now calls out GD&T. They are inclined to continue using the ANSI Y14.5M-1982 spec on the few drawings that do callout GD&T even to its limited use without changing any conventions. It descnoes typical applications and minimum content requirements. He said If you want use to use the newest standard then teach use this 2000 spec (i.e Y14.100-2000) not the out-of-date Y14.5M-1994 standard, and he caught me off guard. ASME Y14.24M-1989 ENGINEERING DRAWING AND RELATED DOCUMENTATION PRAC11CES TYPES AND APPLICATIONS OF ENGINEERING DRAWINGS 1 GENERAL 1.1 Scope This Standard defines the types of engineering drawings most frequently used to establish engineerĀ ing requirements. Proposed changes by DoD activities must be submitted to the DoD Adopting Activity: Commander, U.S. The lead designer for the department took me to task after I corrected their older drawings for errantly defined feature control symbols. ASME Y14.5 ADOPTION NOTICE ASME Y14.5, Dimensioning and Tolerancing, was adopted on 9 February 2009 for use by the Department of Defense (DoD). I feel silly for not doing my homework before asking the question. Indeed ASME Y14.5M-1994 is the current standard.
