ASTM F29-97 (R2022) is a standard specification that outlines the requirements for dumet wire used in glass-to-metal seal applications. Dumet wire is a round, copper-coated 42% nickel-iron wire that is primarily designed for sealing to soft glass. The standard covers various properties and requirements for this wire, including chemical composition, oxide coatings, dimensions, internal and surface workmanship, and storage characteristics.
The standard also specifies the tests that need to be conducted on the dumet wire to ensure its quality. These tests include evaluating thermal expansion, color of coating, diameter, reducible oxides, copper analysis, and metallography.
