ASME Code vs. ASTM Code: What’s The Difference?

ASME Code vs. ASTM Code graphic

There are many codes and standards relevant to industrial heating equipment, including ANSI, ASME, API, and ASTM just to name a few.

As a result, when shopping their options, many of our customers and clients need to do a bit of research to fully understand what each code or standard indicates about the equipment, and which codes and standards are specifically relevant to their industry or application.

Here, we’ll dive into a quick comparison of ASME code and ASTM code, reviewing their similarities and differences.

Understanding ASME Code

ASME – which stands for American Society of Mechanical Engineers – is one of the leading international standard and code developers for the mechanical engineering industry. They are a non-profit organization that works to encourage collaboration across engineering disciplines and to promote art and science.

Also referred to as ASME Boiler & Pressure Vessel Code or BPVC, ASME code regulates the design, development, and construction of boilers and pressure vessels used in various industries. The guidelines dictated by ASME provide safety criteria intended to help prevent accidents and make mechanical equipment safer.

Equipment that is ASME code stamped has been carefully and thoroughly inspected and meets the rigid quality and safety standards established by ASME’s Boiler & Pressure Vessel Code.

Essentially, equipment that adheres to ASME code meets high level quality and safety standards. As a result, the ASME code stamp is an important one to look for if you’re purchasing a boiler or pressure vessel for your facility.

Understanding ASTM Code

ASTM refers to ASTM International, but used to stand for American Society for Testing and Materials.

This organization publishes technical standards related to the quality of the materials that can be used in the manufacture of various products and pieces of equipment, including those built to ASME standards. The standards are developed by committees and are often adopted into other codes and made mandatory by other regulations.

It is perhaps relevant to note that ASTM does not play a role in enforcing the requirements they establish for the various materials, products, systems and services to which their codes apply.

It’s a good idea to ensure that the equipment you are purchasing meets ASTM code standards and is built with high quality, approved materials.

Comparing ASME and ASTM Codes

As you likely understand from the quick overview of the two codes above, ASME and ASTM standards are related yet separate. The two entities have often cooperated to create material specifications that apply to the industrial heating industry.

Equipment built to ASME standards is often built using the materials designated by ASTM code (though it’s also important to note that there are also many ASTM materials that are not appropriate for use in ASME code stamped equipment manufacturing).

These are just two of the various codes that apply to industrial heaters and heating systems. As you’re shopping your equipment options, they are two important standards to keep in mind.
