RATIONALEX1.1 This standard is needed to ensure a high qualitymaterial for use in biological applications. The chemical,physical and mechanical requirements serve as criteria for ahigh-purity, co
18、nsistent product that can be implanted in thebody. These requirements provide specifications for biocom-patible grades of aluminum oxide for use in the physiologicalenvironments.X2. BIOCOMPATIBILITYX2.1 No known surgical implant has ever been shown to becompletely free of adverse reactions in the hu
