A Brief History and Overview of the ASME Y14.5 GD&T Standards

The ASME (or American Society of Mechanical Engineers) founded in 1880, is a non-profit organization dedicated to promoting the sharing of knowledge and career development skills of engineering arts and sciences in 151 countries. ASME’s 130,000 members can be found at all the stages of an engineering career, from college students to corporate executives.

Standards of the ASME are created by a committee of experts using an open, consensus-based method. The development of these standards is voluntary unless incorporated into business contracts or regulations enforced by government agencies.

In 1982, the first GD&T (Geometric Dimensioning and Tolerancing) standards were introduced to the ASME. This standard was created to unify design and interpretation, minimizing errors in the production of parts and assemblies. The standard was revised in 1994 and again in 2009. The current ASME Y14.5.2-2000 exam is set to the 1994 standard with certificates offered at a Technologist and Senior level. A new exam based on the 2009 standard is expected to be introduced in 2017.

Why is GD&T Necessary?

GD&T knowledge is highly sought after by employers of engineering-related positions as it reduces the amount of error, cutting manufacturing and inspection costs. It’s a standard that unifies drawings and interpretations, improving communication between designers, drafting, quality and inspection teams.

A drawing is a contract and GD&T minimizes the variances of interpretation ensuring that the product delivered is exactly what the designer envisioned.

How is the ASME Y14.5 GD&T Standard applied to GD&T Basics?

The GD&T Basics course was created to provide you with a Technologist level of knowledge. This is based on the Pareto method of learning, bringing you 20% of the information you will be using 80% of the time.  We are confident that if you are interested in taking the ASME GD&T Technologist Level Certification exam, you will be armed with the information you need to achieve this certification.

GD&T Basics takes the complexity out of learning Geometric Dimensioning and Tolerancing and makes sure you know how to use it. Our course is available 24 hours a day, 7 days a week on the device of your choice. As a student, you will have direct access to our instructors who can provide you with answers to any specific GD&T questions you might have.

You will also have access to our Premium Wall Chart. This is the best GD&T cheat sheet you’ll find anywhere! You can hang this up in your office and refer to it throughout your workday. A free version of our wall chart is provided to anyone who signs up for our mailing list.

All our students can receive a Certificate of Completion after finishing the course. Our team is available to verify your certification is requested by a current or potential employer.

All our course instructors are Senior level ASME certified and we want to share this knowledge with you. That’s why we are currently developing an Advanced, Senior Level course for additional training, available in 2017.
