ASTM F1089-02

Standard Test Method for Corrosion of Surgical Instruments

1.1 This test method covers general test procedures and evaluation criteria for the corrosion resistance of surgical instruments intended for reuse in surgery and fabricated from stainless steel such as, but not limited to, those listed in Specification F 899.

1.2 Austenitic (Class 3), martensitic (Class 4), and precipitation hardening (Class 5) materials shall use the boil test and the copper sulfate test.

1.3 Ferritic (Class 6) materials shall use the copper sulfate test.

1.4 The copper sulfate test is used to detect chromium depletion at the grain boundaries caused by improper heat treatment or improper cold working of austenitic materials.

1.5 The copper sulfate test is used to detect improper heat treatment of martensitic materials.

1.6 The boil test is applicable to martensitic, austenitic, and precipitation hardened materials to detect surface imperfections.

1.7 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.8 This standard does not purport to address all of the safety concerns, if any, 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.
