This standard outlines procedures for preparing, installing, and analyzing metallic corrosion coupons. Factors considered in the interpretation of results obtained from these corrosion coupons are also included for the use of oil and service industry personnel. This standard is maintained by TG 409.
Ballast water carried by ships keeps them upright during loading and offloading operations and provides balance, stability, and trim during sailing. Because ballast water is loaded from the surrounding port or coastal waters, organisms in the ballast water sometimes establish populations resulting in biological invasions, which may have severe ecological or economic impacts. This standard is designed to test the effect of long-term accelerated exposure of treated water on coating systems.
