BS EN 12540:2000 PDF

BS EN 12540:2000 specifies the requirements for nickel, nickel plus chromium, copper plus nickel and copper plus nickel plus chromium electrodeposited coatings applied to iron and steel, to zinc alloys and to copper and copper alloys to provide an attractive appearance and corrosion resistance. The nickel and copper plus nickel coatings without chromium topcoats that are specified in this standard are suitable for applications in which tarnishing is prevented by rubbing or handling in service, or by the use of topcoats other than chromium. They are also suitable for those applications where tarnishing is of no importance.
