The ASME Y14.5-2009 Standard on Dimensioning and Tolerancing

The new ASME Y14.5 (2009) dimensioning and tolerancing standard was published in April, 2009. According to the American Society of Mechanical Engineers (ASME), "a consensus committee of experts revised Y14.5 for 21st-century applications." The new standard is a replacement of ASME Y14.5M-1994.

The revised standard includes changes to:

• The concept of feature of size
• Datum references and degrees of freedom
• Composite position tolerances
• Surface boundaries and axis methods of interpretation
• Profile tolerances
• Symbology and modifiers tools 

As the foremost expert on GD&T, ETI president Alex Krulikowski was involved in creating this new version of ASME Y14.5. He has developed several products to help with the transition from the 1994 to 2009 standard:

"Deliberations on Dimensioning and Tolerancing Standards" by Alex Krulikowski
Utilizing the statistics collected from a survey regarding plans for companies to either adopt the new standard or adopt ISO standards, Alex has developed a white paper addressing these issues.

Abstract/Synopsis: The new ASME Y14.5-2009 dimensioning and tolerancing standard was published in April, 2009. Many companies are faced with a decision to continue working in their current dimensioning and tolerancing standard, adopt the new ASME 2009 standard, or adopt the ISO standards. This paper contains three topics that will help organizations decide what path may be the best for them:

• A summary of the major changes to the ASME standard
• The results of a survey that provides insight into what other companies are planning
• The author’s deliberations and recommendations on changing dimensioning standards
