New ASME Y14.35 on Document Revisions

The ASME Y14 series of drafting standards is an essential part of the engineering toolkit.  A number of documents in the set have been updated during the last year or so.  Now the ASME Y14.35, “Revision of Engineering Drawings and Associated Documents,” has been revised.  The new 2014 Edition replaces the previous 1997 Edition, which was numbered ASME Y14.35M (now obsolete).  You can order your copies of the new publication from Document Center Inc. now.

This part of the series addresses the issue of releasing revisions for drawings and documents.  It’s not uncommon for companies to have questions about this, since internal documentation is part of many organizations’ engineering resources.  The Y14.35 identifies what revisions are and covers how to identify and record them.

Updates to the previous edition are found in the following areas of the standard:

  • Paragraph 1.1, the Scope section
  • Paragraphs 3.4, 3.8.1 and 3.8.2, and 3.27 in the Definitions Section
  •  Paragraph 4.7 in the Drawing Practices Section
  • Paragraph 5.2 in the Edition Identification Section

Since the new edition is a technical update, you’ll want to get a copy if you use this document.  You can order it on the Document Center website at  Or you can contact our staff by phone (650-591-7600), fax (650-591-7617) or email (  The document is expected to ship in early- to mid-September.

ASME-Y14.5 – 2009 Edition – One of our top-selling engineering standards

ASME-Y14.5 – 2009, Geometric Dimensioning and Tolerancing, is one of Document Center Inc.’s all-time top selling engineering standards.  It is the basic document for stating and interpreting geometric dimensioning and tolerancing requirements for use on engineering drawings and in related documents.

The history of the Y14 series on engineering drawings goes back to 1915, some 35 years after the ASME organization was founded.   It’s roots come from the need of automobile manufacturers and other industrial facilities to standardize engineering drawings and terminology among their suppliers.  The ASME-Y14.5 (also known as ASME-Y14.5M, from it’s now obsolete 1982 metric edition) is the centerpiece of this well-used series.

Important changes in the new ASME Y14.5 – 2009 include datum references and degrees of freedom, composite position tolerances, surface boundaries and axis methods of interpretation, profile tolerances, and symbology and modifiers tools.
