ASTM F86 2012 Edition, “Standard Practice for Surface Preparation and Marking of Metallic Surgical Implants,” has just been released and is now available in paper or pdf format from Document Center Inc. The surface treatments documented in this practice are intended to improve the corrosion resistance of metallic surgical implants manufactured from iron, cobalt, titanium, and tantalum base materials.
Iron particles, ceramic media, and other foreign particles may become smeared over or imbedded into the surface of implants during processing operations such as forming, machining, tumbling, bead blasting, and so forth. These particles should be removed to minimize localized rust formation and superficial blemishes.
The need for an additional implant surface treatment such as secondary passivation in nitric acid should be evaluated for localized implant surfaces that have electrochemical or laser product markings created after the final surface treatment. This practice provides a description of surface characteristics, methods of surface preparation, and methods of marking for metallic surgical implants.
The 3-page ASTM F86-12 replaces the ASTM F86-04(2009) (2004 Edition reaffirmed in 2009) which is now obsolete. Values are stated in inch-pound units with mathematical conversions to SI units in parentheses (for your information only — not to be considered standard).
All current ASTM standards and many obsolete revisions are available from Document Center Inc. at our website, www.document-center.com. Many ASTM’s are available in redline editions as well, just ask us about this if you’re interested. FYI: A listing of all ASTM standards on Surgical Implants will be available on our website when the new updated version is released in early July. Be sure to check it out!
