ASTM A370, Standard Test Methods and Definitions for Mechanical Testing of Steel Products – New 2011 Edition available

ASTM-A370 2011 Edition titled “Standard Test Methods and Definitions for Mechanical Testing of Steel Products” has just been released.  These test methods cover procedures and definitions for the mechanical testing of steels, stainless steels, and related alloys.  The new 2011 edition replaces the previous 2010 issue.

ASTM-A370 test methods center on Ductile vs. Brittle Behavior.  Body-centered-cubic or ferritic alloys exhibit a significant transition in behavior when impact tested over a range of temperatures. At temperatures above transition, impact specimens fracture by a ductile (usually microvoid coalescence) mechanism, absorbing relatively large amounts of energy. At lower temperatures, they fracture in a brittle (usually cleavage) manner absorbing appreciably less energy. Within the transition range, the fracture will generally be a mixture of areas of ductile fracture and brittle fracture.

The temperature range of the transition from one type of behavior to the other varies according to the material being tested. This transition behavior may be defined in various ways for specification purposes.

The specification may require a minimum test result for absorbed energy, fracture appearance, lateral expansion, or a combination thereof, at a specified test temperature.

The specification may require the determination of the transition temperature at which either the absorbed energy or fracture appearance attains a specified level when testing is performed over a range of temperatures. Alternatively the specification may require the determination of the fracture appearance transition temperature (FATTn) as the temperature at which the required minimum percentage of shear fracture (n) is obtained.

New Revision C released for MIL-HDBK-189, Reliability Growth Management

MIL-HDBK-189 Revision C has just been released.  The document, entitled “Reliability Growth Management,” replaces the previous revision, MIL-HDBK-189B with administrative notice 1.  This guide is intended for use on systems/equipment during the development phase by both producer (supplier) and consumer (military) personnel.

Reliability growth management procedures were developed to help guide the materiel acquisition process for new military systems. Generally, these systems require new technologies and represent a challenge to the state of the art. Striving to meet these reliability requirements represents a significant portion of the entire acquisition process and, as a result, the setting of priorities and the allocation and reallocation of resources such as funds, manpower and time are often formidable management tasks.

Reliability growth techniques enable acquisition personnel to plan, evaluate and control the reliability of a system during its development stage. The reliability growth concepts and methodologies presented in this handbook have evolved over the last few decades by actual applications to Army, Navy and Air Force systems. Through these applications, reliability growth management technology has been developed to the point where considerable payoffs in system reliability improvement and cost reduction can be achieved.

This handbook provides procuring activities and development contractors with an understanding of the concepts and principles of reliability growth, advantages of managing reliability growth, and guidelines and procedures to be used in managing reliability growth.

MIL-HDBK-189C is not intended to serve as a reliability growth plan to be applied to a program without any tailoring. This handbook, when used in conjunction with knowledge of the system and its development program, will allow the development of a reliability growth management plan that will aid in developing a final system that meets its reliability requirements and lowers the life cycle cost of the fielded systems.

The primary change in this new release is the addition of PM2 (Planning Model Based on Projection Methodology) planning model.  However, there are no guides to the actual changes in the document due to the extensive nature of the update.  Because the handbook is only 149 pages, detailed development of underlying theory and estimation procedures are not provided.  There’s a two-page bibliography at the end of the handbook to assist the user find additional information.

To purchase all of the publicly distributed Military Handbooks, including the new MIL-HDBK-189C, use our Document Center 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 to assist you with all your standards needs and questions.

New ASTM D6251 – 11/D6251M – 11 Standard Specification for Wood-Cleated Panelboard Shipping Boxes

There’s a new 2011 revision for ASTM D6251/D6251M, “Standard Specification for Wood-Cleated Panelboard Shipping Boxes.”  The 16 page document covers the fabrication and closure of empty and full wood-cleated panelboard boxes (wooden crates).

Boxes are firstly classified according to box type: Type I, Type II, Type III, and Type IV.  Then they’re further segregated according to class: Class 1 and Class 2.  There’s additional classification for style:  Style A, Style A1, Style B, and Style C through K.  And also classification according to preservative treatment; Treatment A and Treatment B.  Then lastly, according to load type: Type 1, Type 2, and Type 3.

Panels using this standard are fabricated by nailing, stapling, or gluing panelboard to cleats.

Specified requirements are given for fastener component test, fastener test for securing cleats to panelboard panels, lateral resistance test, direct withdrawal resistance test, oxine copper preservative test, zinc napthenate preservative test, and preservative dryness test.

The specification has been adopted by the U.S. government as a replacement for the popular Federal specifications, PPP-B-576 (cancelled in 1998) and PPP-B-601 (cancelled in 1999).

ASTM D6251 and all ASTM standards can be purchased from Document Center Inc. at our website, www.document-center.com.  We have copies of the obsolete Federal Specifications as well.  Or contact us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).  We can assist you with all your standards questions and requirements.

New MIL STD 2105 Revision D – Hazard Assessment Tests for Non-Nuclear Munitions

New MIL-STD-2105 Revision D, titled “Hazard Assessment Tests for Non-Nuclear Munitions” and dated 4/19/2011, is now available.  This standard provides or references tests and test procedures for the assessment of safety and Insensitive Munitions (IM) characteristics for all non-nuclear munitions, munition subsystems, and explosive devices.

MIL STD 2105 applies to all non-nuclear munitions (i.e., all-up missiles, rockets, pyrotechnics) and munitions subsystems (e.g., warheads, fuzes, cartridge actuated devices, propulsion units, safe and arm devices, pyrotechnic devices, chemical payloads) and other explosive devices. The standard assumes that it may not be possible to test against all threats.  Therefore, it recommends you select the most probable, credible stimuli that are expected to cause the greatest damage to life, property, or combat effectiveness.

Three sets of tests are commonly used to assess munitions with respect to hazards: IM tests as contained or contained in this standard; Hazard Classification (HC) tests used to classify munitions for transportation and storage purposes; and basic safety tests used to assess munition safety and suitability response or system vulnerability.  In order to best utilize limited resources and avoid test redundancy, it is suggested you tailor IM test plans to the maximum extent possible, so that all three sets of tests can be addressed in one coordinated test program with the minimum number of samples.

Twenty-five other standards are referenced in MIL-STD-2105 for many of the actual tests themselves.  The standard itself is 37 pages and replaces the MIL-STD-2105 Revision C with its 2 administration notices.  The document is intended for military use, not commercial applications.

The standard, and all publicly available military standards and specifications, is available from Document Center Inc. at our website, www.document-center.com.  Or contact us for more information by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).  We are available to personally assist you from 8 am to 5 pm California time.

New AMS-B-20148 Revision B released on Brazing Sheet, Aluminum Alloy

New AMS-B-20148B, dated 5/24/2011, is titled “Brazing Sheet, Aluminum Alloy.”  It covers aluminum alloy brazing sheet for use in brazed aluminum joints.  The document is another standard that migrated from a military specification to an industry standard in the late-1990’s.

The document was originally released as MIL-B-20148 in 1951.  It was cancelled at the Revision D level in 1998 and was replaced by the AMS-B-20148 at that time.  Since then, the AMS version has undergone two revisions, with the Revision B being the latest.

There are no relevant Alloy or UNS numbers for this particular standard.

The new revision recognizes technical equivalency for two recently published specifications; brazing sheet #23-F is superseded by AMS-4465, brazing sheet #24-F is superseded by AMS-4460.

Additionally, paragraph 3.1 provides the complete list of superseding requirements applicable to #11-0, #12-0, #21-F, #22-F, #23-F, and #24-F.

AMS-B-20148B and all AMS Standards are available from Document Center Inc. You can also reach us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).  These items are in stock for immediate processing.

MIL-STD-171 New Revision F released — It’s the military standard on Finishing of Metal and Wood Surfaces

Document Center recently notified its customers about the new MIL-STD-171 F dated 5/31/2011 on Finishing of Metal and Wood Surfaces.  The widely used standard covers the minimum requirements for finishing, and otherwise treating, metal and wood surfaces.  It replaces the MIL-STD-171E with Change Notice 1.

The document’s stated purpose is to establish finish system codes which link or cross reference specific specification information for finishing and otherwise treating metal and wood surfaces. It also serves as a general guide to the selection of suitable finishing materials, procedures and systems.  It covers both organic (paint, varnish, and so on) and inorganic (metal plating, phosphatized metal, and the like) coatings.

Of course, specialized systems particular to individual agencies are covered by drawings, specifications and standards published by those organizations and supplement MIL-STD-171.  Those procurement documents should make direct reference to the applicable specification. For example, MIL-STD-186 covers painting and other finishing of Army Missile weapon systems.

Finish system code numbers in the tables of MIL-STD-171 are intended to remain stable, since those code numbers are commonly referenced on drawings, in contracts and in end items specifications.

Where a system in a previous edition of the standard has been deleted from this new revision, the system to be used as a substitute is noted in the tables.

This standard, and all publicly distributed military standards, are available from Document Center Inc. Or contact us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).  Staff is available to help you with all your standards questions and requirements.
