When continuous or intermittent intravenous infusion is required, a catheter is surgically implanted at least 5 days before the start of treatment. The animals are maintained on continuous infusion with physiological saline between implantation and the start of test item administration. [Pg.155]

The test method ASTM F7464 covers the determination of the resistance to either pitting or crevice corrosion of passive metals and alloys from which surgical implants are produced. The resistance of surgical implants to localized corrosion is carried out in dilute sodium chloride solution under specific conditions of potentiodynamic test method. Typical transient decay curves under potentiostatic polarization should monitor susceptibility to localized corrosion. Alloys are ranked in terms of the critical potential for pitting, the higher (more noble) this potential, the more resistant is to passive film breakdown and to localized corrosion. (Sprowls)14...

Electrochemical techniques have also been used to provide a rapid test in ASTM F 746, Test Method for Pitting or Crevice Corrosion of Metallic Surgical Implant Materials. A specimen is anodically p>olarized to stimulate pitting and then returned to a less positive preset potential to determine if repassivation will occur. This is repeated at successively higher preset potentials until the final, or criticcJ potential is determined. More resistcmt materitJs display higher critical potentials. This relatively brief test does not wait for pits to initiate tmd reduces variabiUty by maintaining the potential of the specimen. [Pg.777]
