What is the difference between ASTM and ASME

ASTM and ASME (American Society of Mechanical Engineers) both develop standards, but for different areas. ASTM focuses on materials and testing methods, while ASME provides standards for construction and pressure vessels.

Explanation of the Difference Between ASTM and ASME

ASTM (American Society for Testing and Materials) and ASME (American Society of Mechanical Engineers) are two different organizations in the USA that deal with standards and specifications in the fields of materials, construction, and testing procedures. Here are the main differences between ASTM and ASME:

  1. Purpose of the Organization:
    • ASTM: This organization focuses on the development and publication of international standards and specifications for materials, products, systems, and services. ASTM standards are used in many industries worldwide.
    • ASME: In contrast, ASME is primarily specialized in engineering practices and codes. It develops regulations that deal with the design, inspection, and testing of pressure vessels, pipelines, and other mechanical components.
  2. Areas of Application:
    • ASTM: ASTM standards cover a wide range of industries, including construction, aerospace, chemicals, electronics, petroleum, environment, and more. They primarily concern materials and their testing procedures.
    • ASME: The codes and standards of ASME are more specific and mainly focus on the pressure equipment and plant construction. ASME codes are of great importance in the oil and gas industry, power generation, chemical industry, and other sectors.
  3. Products and Standards:
    • ASTM: Here, standards are developed for materials, construction products, testing procedures, and much more. ASTM standards are generally internationally recognized and have extensive applications.
    • ASME: ASME develops codes and standards, such as the ASME Boiler and Pressure Vessel Code (BPVC) or the ASME B31 Code for Pressure Piping. These are more specific to the pressure equipment and plant construction and often carry legal enforceability in various jurisdictions.

In summary, ASTM and ASME are two different organizations that have different focuses and areas of application. ASTM develops standards for a wide range of industries, while ASME specializes in the field of pressure equipment and plant construction.
