ASTM F 1089 Document Information:
Title
Standard Test Method for Corrosion of Surgical Instruments
ASTM International
Publication Date:
Dec 10, 2002
Scope:
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.
Austenitic (Class 3), martensitic (Class 4), and precipitation
hardening (Class 5) materials shall
use the boil test and the copper sulfate test.
Ferritic (Class 6) materials shall use the copper sulfate test.
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.
The copper sulfate test is used to detect improper heat treatment of
martensitic materials.
The boil test is applicable to martensitic, austenitic, and
precipitation hardened materials to
detect surface imperfections.
The values stated in SI units are to be regarded as the standard. The
values given in parentheses
are for information only.
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.
