Bibliography

Defines requirements for nickel, nickel plus chromium, copper plus nickel and copper plus nickel plus chromium electrodeposited coatings applies to steel, iron, zinc alloys and copper and copper alloys to provide an attractive appearance and corrosion resistance. Nickel and copper plus nickel coatings without chromium topcoats specified are suitable for applications where tarnishing is prevented by rubbing or handling in service, or by use of topcoats other than chromium. Also suitable for applications where tarnishing is of no importance.
