Boiler Code Week 2025 - GD&T Fundamentals with Stack and Gauging Applications Course

Congratulations on completing ASME Code Week!

Your dedication to intensive learning demonstrates your commitment to engineering excellence and public safety—core values that define the ASME community. This achievement reflects your investment in professional development and your role in upholding the rigorous standards that have made ASME a globally trusted name in engineering for over 140 years.

This badge is awarded to participants who successfully completed an accredited course offered during ASME Boiler Code Week. Earning this badge signifies active engagement in technical learning aligned with the ASME Boiler and Pressure Vessel Code (BPVC), as well as a demonstrated commitment to advancing safety, quality, and compliance in engineering practice.

Description of Course:

This course is an immersion into the rules, symbols, and other concepts of the American Standard for Geometric Dimensioning & Tolerancing: ASME Y14.5-2018. The course also covers important differences between older versions of the standard and the current ISO GD&T Standards. Key fundamental rules, all control symbols, datums and datum schemes, basic dimensions, virtual conditions, modifiers, and the infamous Rule #1 are all covered in detail.

You Learned To:

• Describe the tolerance zones defined by each symbol.

• Determine when to use Rule #1 to control form and when other controls are appropriate.

• Recognize correct syntax for feature control frames.

• Relate common gauging and inspection methods to geometric tolerance zones defined by feature control frames.

• Correctly apply and interpret the Maximum Material Condition (MMC), Least Material Condition (LMC), and other modifiers.

• Assess various datums and datum schemes against product functionality and manufacturing and inspection performance.

• Recognize the need for product-specific GD&T guidelines and list the steps required to create them.
