This specification covers palladium in the form of rod, wire, strip, and sheet material for electrical contacts. Raw materials shall be of such quality and purity that the finished product (produced by cold working, annealing, turning, grinding, or pickling as are required) will have the properties and characteristics prescribed in this specification. The material shall conform to the chemical composition requirements prescribed for palladium, platinum group (iridium, platinum, rhodium, osmium, and ruthenium), gold, silver, and copper, total impurities, lead, antimony, bismuth, tin, arsenic, cadmium, zinc, iron, and other elements. Ultimate tensile strength, elongation, microhardness (Knoop or Vickers), hardness (Rockwell or Rockwell Superficial), or a combination of these mechanical properties may be specified as temper criterion. Tension and hardness tests shall be conducted to determine conformity to the ultimate tensile strength and elongation, and Rockwell and Knoop hardness, respectively. Inspection of furnished material shall be done by temper test, dimensional test, and spectrographic or chemical analysis when needed.
