New Revision B released for MIL-HDBK-6870, Nondestructive Inspection Program Requirements for Aircraft and Missile Materials and Parts

MIL-HDBK-6870 Revision B, “Nondestructive Inspection Program Requirements for Aircraft and Missile Materials and Parts,” has just been released and is now available from Document Center Inc.  This 28-page handbook provides the guidance for defining the requirements for establishing a nondestructive inspection (NDI) program for evaluation of structural components in development, production or sustainment of U.S. military aircraft and missiles systems. It is directly applicable when referenced in the item specification contract or order.

MIL-HDBK-6870 is the replacement document for the old MIL-I-6870, which was withdrawn in 1996.  It applies to structures for aircraft and missiles when the design activity or system specification requires nondestructive inspection for production acceptance, and recurring nondestructive inspection for long-term sustainability.

This handbook may also be applicable to mechanical equipment, subsystems and propulsion systems but the guidance should be tailored for such use. This handbook applies to all phases of the system life cycle: acquisition, modification and sustainment.

The NDI Program Plan should be developed at the beginning of the development phase and should define all NDI requirements to be adhered to during system development, test, production, and sustainment.

Like all military handbooks, this document is for guidance only and cannot be cited as a requirement.  Marginal notations are not used in this revision to identify changes with respect to the previous issue due to the extent of the changes.  Revision B replaces the previous edition, MIL-HDBK-6870A, which is now obsolete.

All publicly distributed (non-classified) military specifications, standards, and handbooks are available from Document Center Inc.  We have an extensive collection of obsolete documents as well as the current editions.  Use 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 available Monday to Friday from 6 am to 5 pm Pacific Time to help you with any questions you may have.

New ASTM E1742/E1742M 2011 Edition released on Radiographic Examination

ASTM E1742/E1742M, 2011 Edition, titled “Standard Practice for Radiographic Examination” has just been released and is available now from Document Center Inc.  This practice establishes the basic parameters for the application and control of the radiographic method. The standard is written so it can be specified on the engineering drawing, specification, or contract.

E1742/E1742M establishes the minimum requirements for radiographic examination for metallic and nonmetallic materials.  The criteria presented for the radiographic examination are applicable to all types of metallic and nonmetallic materials.  However, the standard is intended to control the quality of the radiographic images and not to establish acceptance criteria for parts and materials.

It is not a detailed how-to procedure to be used by a non-destructive test (NDT) facility and so must be supplemented by a detailed procedure. ASTM Test Methods E1030, E1032, and E1416 contain information to help develop detailed technique/procedure requirements.

Again, because the number of the standard has both the E1742 and E1742M included, the values are stated in either SI units or inch-pound units.  They are to be regarded separately as standard because the values stated in each may not be exact equivalents.  Therefore, each system needs to be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

This ASTM Standard, and all ASTM documents, may be purchased from Document Center Inc. through our website, www.document-center.com.  Or call us at 650-591-7600, send us a fax at 650-591-7617, or email us at info@document-center.com.  Staff is ready to assist you with your orders and questions.
