Annotation of standard text ASTM B685-20(2025) :
This specification deals with the standard requirements for palladium-copper alloy in the form of rod, wire, strip, and sheet material for use in electrical contacts. The specimen shall be produced from raw materials of such quality and purity by cold working, annealing, turning, grinding, or pickling. Material shall meet the chemical composition requirements for palladium, copper, silver, iron, zinc, cadmium, lead, and aluminum which shall be determined by spectrographic or chemical analysis. Temper test (hardness or tension) shall be conducted to determine the mechanical properties which shall be in conformity with the ultimate tensile strength, elongation, Knoop or Vickers microhardness, and Rockwell or Rockwell superficial hardness specifications. Visual examination shall be done on the furnished materials.
