Note:
In technical contexts, ASTM refers to the American Society for Testing and Materials, and ASME refers to the American Society of Mechanical Engineers. In the table, ASME standards are often prefixed with “S” (e.g., SA or SB) to indicate they are adopted from ASTM for boiler and pressure vessel codes.
