ASTM F1089: Standard Test Method for Corrosion of Surgical Instruments
ISO 13402: Surgical and dental hand instruments – Determination of resistance against autoclaving, corrosion and thermal exposure
DIN EN ISO 13402: Chirurgische und zahnärztliche Handinstrumente – Bestimmung der Beständigkeit gegenüber Sterilisation, Korrosion und Wärmebehandlung

This test method covers general test procedures and evaluation criteria for the corrosion resistance of stainless steel surgical instruments intended for reuse in surgery.
Distilled water, followed by a copper sulfate solution, are used as test fluids.
A visual inspection without magnification (according to the standard) is performed before and after the test to evaluate the result.
