New TT-C-490 Revision F released for Chemical Conversion Coatings and Pretreatments for Metallic Substrates (Base for Organic Coatings)

TT-C-490 Revision F, “Chemical Conversion Coatings and Pretreatments for Metallic Substrates (Base for Organic Coatings),” has just been released and is available now from Document Center Inc. in either pdf or paper format.  This federal specification replaced MIL-C-490 and MIL-P-14504 and is one of the most commonly used plating specifications we sell.

TT-C-490F covers processes, pre-treatments, and pre-primer surface preparations of metallic substrates for coating applicators.  It covers metal surface preparation for delaying corrosion initiation and promoting primer adhesion. In addition, this specification covers the testing requirements for qualification of conversion coatings, the pre-treatments and pre-primer coatings.

The new 24-page revision has extensive changes from the now-obsolete 17-page TT-C-490E from 2002, so there are no lines in the margins showing you the updated material.   Changes appear to have been made throughout the document.

New ASTM F86 2012 Edition on Standard Practice for Surface Preparation and Marking of Metallic Surgical Implants

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!

You may also contact us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).  Our staff is available during business hours California time to assist you with all your standards needs and questions.

New ASTM B600 2011 Edition released on Standard Guide for Descaling and Cleaning Titanium and Titanium Alloy Surfaces

ASTM B600-11 Edition, “Standard Guide for Descaling and Cleaning Titanium and Titanium Alloy Surfaces,” has just been released.  This new 2011 edition replaces the ASTM B600-09 which is now obsolete.

The guide covers a cleaning and descaling procedure useful to producers, users, and fabricators of titanium and titanium alloys for the removal of ordinary shop soils, oxides, and scales resulting from heat treatment operations and foreign substances present as surface contaminants.

ASTM B600 is not intended to be mandatory for removal of any of the indicated soils but rather serve as a guide when titanium and titanium alloys are being processed in the wrought, cast, or fabricated form.

It is recommended that the materials shall be subjected to soil removal prior to heat treatment or application of acid treatment. Mechanical descaling methods such as sandblasting, shot blasting, and vapor blasting may be used to remove hot work scales and lubricants from titanium surfaces.

Recommended post treatment of shot or abrasive blasted titanium surfaces may include acid pickling to ensure complete removal of surface contaminants. For chemically milled materials, salt bath conditioning may be required to remove the oxygen-contaminated layer. Acid etching treatment may be required following mechanical abrading or chemical conditioning of materials to completely clean the surface.

This new ASTM guide and all ASTM standards are available from Document Center Inc. at our website, www.document-center.com.  Or contact us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).  Our staff is available from 8 am to 5 pm, Monday through Friday, California time.  We have an extensive collection of obsolete ASTM revisions as well.

AAMI-ST79 – The new 2010 Edition is available for preorder now

The AAMI recommended practice ST79, Comprehensive guide to steam sterilization and sterility assurance in health care facilities, is now approved in a new 2010 Edition and public distribution is pending.

The standard consolidates 5 previous AAMI steam sterilization standards, the AAMI ST33, AAMI ST35, AAMI ST37, AAMI ST42 and AAMI ST46.  It was the first AAMI standard to be released in a binder edition, since the material covered is extensive.  The binder format facilitates easy access to the various topics, like lowering and limiting bioburden before sterilization, properly preparing items for sterilization, selecting the appropriate sterilization parameters, and establishing and implementing controls to maintain the sterility of sterilized items until they are used.

Users of this standard will find guidance to promote assurance of sterility and to guide health care personnel in the proper use of processing equipment.  The document includes functional and physical design criteria for a number of sterilization processing areas  including decontamination, preparation, sterilization, and sterile storage areas.  There are sections to assist with staff qualifications, education and other personnel considerations.  Also covered are  processing procedures,  installation, care and maintenance of steam sterilizers, quality control and, of course, quality process improvement.

The new ANSI/AAMI-ST79:2010 replaces the previous 2006 Edition with both Amendments 1 and 2, which is no longer available.  Because the new ANSI/AAMI-ST79 was only recently approved (9/3/2010), there will be a delay until the new edition is available.  Normal lag time can be from 1 to 3 months for the formatting and publishing functions to take place and the standard to become publicly available.

To purchase your copy of ANSI/AAMI-ST79, use our website at www.document-center.com, or call us at 650-591-7600, fax 650-591-7617, or email to info@document-center.com.

Your order can be placed now and shipped as soon as it is released.
