The popular specification, AN 960, “Washer, Flat,” was withdrawn on September 16th of this year in favor of the NAS-1149, “Washer, Flat.” The cancellation notice affects Revision 21 for AN 960, which is now obsolete.
The five page cancellation notice provides the user with a detailed interchangeability and substitution table, showing the old AN960 part numbers and the correct replacement numbers in the new NAS 1149 numbering schema.
NAS 1149 duplicates most of the AN960 parts, but additional material options permit use of titanium and other special high strength alloy materials. The washer is used in aerospace applications.
Both AN and NAS 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). We’re happy to assist you with all your standards and specifications requirements.
ASTM E1444, “Standard Practice for Magnetic Particle Testing,” has been issued as a new 2011 Edition with a redesignation to ASTM E1444/E1444M-11. This new document number shows that the document has been revamped to include both feet and inches and metric measurements. It replaces MIL-STD-1949, as well as the previous ASTM E1444-05 Edition from 2005.
This practice establishes minimum requirements for magnetic particle testing used for the detection of surface or slightly subsurface discontinuities in ferromagnetic material. Guide ASTM E709 can be used in conjunction with this practice as a tutorial.
Magnetic particle testing consists of magnetizing the area to be examined, applying suitably prepared magnetic particles while the area is magnetized, and subsequently interpreting and evaluating any resulting particle accumulations. Maximum detectability occurs when the discontinuity is positioned on the surface and perpendicular to the magnetic flux.
The magnetic particle testing method is used to detect cracks, laps, seams, inclusions, and other discontinuities on or near the surface of ferromagnetic materials. Magnetic particle testing may be applied to raw material, billets, finished and semi-finished materials, welds, and in-service parts. Magnetic particle testing is not applicable to non-ferromagnetic metals and alloys such as austenitic stainless steels.
ASTM E1444/E1444M establishes the basic parameters for controlling the application of the magnetic particle testing method. This practice is written so that it can be specified on the engineering drawing, specification, or contract. It is not a detailed how-to procedure to be used by the examination personnel and, therefore, must be supplemented by a detailed written procedure that conforms to the requirements of this practice.
This ASTM Standard and all current (as well as many obsolete) Editions can be purchased 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). We are able to answer many questions about standards and welcome your inquiries.
There’s a new edition of the popular Standard Practice for Liquid Penetrant Testing, ASTM E1417-11 2011 Edition. The 11 page revision replaces the ASTM E1417-05(e1) Edition from 2005 and the MIL-STD-6866. The document establishes the minimum requirements for conducting liquid penetrant examination of nonporous metal, and nonmetal components.
The document has been redesignated to ASTM E1417/E1417M. This redesignation means that the document contains measurements in both metric and feet and inches.
This practice is written so it can be specified on the engineering drawing, specification, or contract. It is not a detailed how-to procedure to be used by the inspector and, therefore, must be supplemented by a detailed procedure that conforms to the requirements of this practice. Specification ASTM E165 contains information to help develop detailed requirements.
The penetrant examination processes described in this practice are applicable to in-process, final, and maintenance (in-service) examinations. These processes are applicable for the detection of discontinuities, such as lack of fusion, corrosion, cracks, laps, cold shuts, and porosity, that are open or connected to the surface of the component under examination.
Caution must be exercised in the usage of elevated temperature with components manufactured from thermoplastic materials. Also, some cleaners, penetrants, and developers can have a deleterious effect on nonmetallic materials such as plastics. Prior to examination, tests should be conducted to ensure that none of the cleaning or examination materials are harmful to the components to be examined.
All documents mentioned above, including the new ASTM E1417, are available from Document Center Inc. Use our website, www.document-center.com, or call us (650-591-7600), fax us (650-591-7617) or send us an email (info@document-center.com).

MIL-PRF-22750 Revision G has just been released. Titled “Coating, Epoxy, High-Solids,” the 22-page document replaces the previous edition, Revision F from 1994.
This specification covers the requirements for a two component, high solids epoxy coating. This coating is free of all inorganic hazardous air pollutants (HAPS), including compounds of lead and chromium. The coating is supplied as a kit.
MIL-PRF-22750 provides information on 4 types of coatings, detailed below, as well as additional classes and grades.
Type I – Standard formulation with a maximum volatile organic compound (VOC) content of 340 grams/liter (g/l) (2.8 pounds/gallon (lbs/gal)) as packaged.
Type II – Volatile organic hazardous air pollutants-free (VOHAP-free) formulationto meet maximum VOC content of 340 g/l (2.8 lbs/gal) as packaged.
Type III – Direct to metal, VOHAP-free formulation to meet maximum VOC contentof 340 g/l (2.8 lbs/gal) as packaged. As a direct to metal, this coating willhave enhanced corrosion performance including 1,000 hours salt spray and40 cycles on the cyclic corrosion test. This type is only available insemi-gloss and lusterless colors.
Type IV – Self contained portable kits to include, but not limited to, brush, roller andcartridge application. The kits contain the type II or III epoxy coating.
Originally numbered MIL-C-22750, the document was redesignated MIL-PRF-22750 with the release of Revision F in 1994. This was an effect of mil spec reform, which created the 2 new classes of specifications: Performance (MIL-PRF’s) and Detail (MIL-DTL’s).

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.

MIL-STD-790 Revision G, “Established Reliability and High Reliability Qualified Products List (QPL) Systems for Electrical, Electronic, and Fiber Optic Parts Specifications,” has just been released. The new 24-page revision is for direct reference in established reliability and high reliability electrical, electronic, and fiber optic parts specifications. It defines the criteria for a manufacturer’s qualified product system.
In implementing the Parts Specification Management for Reliability Report (PSMR-1), issued by the Department of Defense in May 1960, the military determined that a manufacturer must provide evidence of (a) adequate production and test facilities, and (b) sound procedures for process control. MIL-STD-790 was developed to provide guidelines.
Manufacturers of established reliability and high reliability electrical, electronic and fiber optic components that are included in the QPL program need to demonstrate to the qualifying activity that a system is in place to integrate all design, planning, manufacturing, inspection, and test functions. Those requirements are described in this standard.
The margins of MIL-STD-790 are marked with asterisks to indicate where changes from the previous issue were made. FYI: This was done as a convenience only and the Government assumes no liability whatsoever for any in accuracies in these notations.
The new MIL-STD-790, and all Military Specifications and Standards, are available from Document Center Inc. at our website, www.document-center.com. Or you may consider phoning us at 650-591-7600, faxing us at 650-591-7617 or sending us an email at info@document-center.com. We’re open from 8 am to 5 pm Monday through Friday, California time.
