Difference between ASTM and ASME Standard

ASTM material standards are developed by the American Society for Materials and Testing, ASTM material standards can include the chemical, mechanical, physical and electrical properties of the material. These standards include both a description of test methods to be performed on building materials, and the size and shape that these materials are to take. Building materials like concrete can be required to meet ASTM standards before being used in construction. Among ASTM A53 and ASTM A106 seamless pipe are widely used.

ASME is the standard of the American Society of Mechanical Engineers. ASME material specifications are based on those published by the ASTM, AWS and other recognized national and international standards. ASME standards are legally required when building infrastructure like bridges, power plant piping and boilers. Among ASME b16.5 are widely used.

Difference between ASTM and ASME Standard:

ASME American Society of Mechanical Engineers Standards
ASTM American Society for Testing and Materials Standards
ANSI American National Flange Standards

They are three different standardization organizations, and each standard has its own system, which is the most influential and applied in the American Standard system.
Among them, ASME standards and ANSI standards cover most of the industrial fields, including materials, processing, technology, testing and so on. ASME cites many ANSI and ASTM standards. For pipes and pipe accessories, these three are basically unified, commonly known as American standard pipes, pipe fittings, pipe accessories (flanges, gaskets, etc.), and ASME is the most used /ANSI standard.

ASTM is responsible for the development and re-enactment of standards for all types of old and new materials. Because it is the test and materials association.

ASME is to selectively absorb and filter these standards for the relevant works used, and to be modified to improve.

ASTM is the US material standard, similar to the domestic GB713

ANSI is a flange standard, similar to domestic HG20615
ASME is a design specification, but since ASME is a complete system, ASTM and ANSI are included in it, such as SA516-70, ASME B16.5.

ASME is a design specification, but ASME is a complete system.
