Which ASTM standard defines solder metal used in applications?

• A. ASTM A 795
• B. ASTM B 32
• C. ASTM B 43
• D. Extracted text

Answer: (B)

ASTM B32 defines solder metal used in applications. This standard, called the Standard Specification for Solder Metal, specifies the compositions and classifications of solder alloys and sets the requirements for their manufacture and testing. It ensures that solders used to join metals—such as copper piping or similar assemblies—have predictable properties like melting range, strength, and compatibility with the base metals, which is essential for reliable joints and uniform performance across installations. The other standards listed cover different material areas and do not define solder metal, so they aren’t applicable to specifying solder alloys. The option that isn’t a standard is not relevant to this topic.
