Historical Standard: ASTM F746-87(1999) Standard Test Method for Pitting or Crevice Corrosion of Metallic Surgical Implant Materials
SUPERSEDED (see Active link, below)
ASTM F746
1. Scope
1.1 This test method covers the determination of resistance to either pitting or crevice corrosion of metals and alloys from which surgical implants will be produced. It is a modified version of an established test and is used as a screening test to rank surgical implant alloys in order of their resistance to localized corrosion.
1.2 This test method applies only to passive metals and alloys. Nonpassive alloys (other than noble alloys) are susceptible to general corrosion and are not normally suitable for implant use.
1.3 The test method is intended for use as a laboratory screening test of metals and alloys which undergo pitting or crevice corrosion, or both.
1.4 The values stated in SI units are to be regarded as the standard.
1.5 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
