NOT MEASUREMENT SENSITIVE MIL STD 464 18 March 1997 ________________ SUPERSEDING (See section 6.5) DEPARTMENT OF DEFENSE INTERFACE STANDARD ELECTROMAGNETIC ENVIRONMENTAL EFFECTS REQUIREMENTS FOR SYSTEMS AMSC A7252 AREA EMCS DISTRIBUTION STATEMENT A.Approved for public release; distribution is unlimited.MIL STD 464 F O R E W O R D 1. This Military Standard is approved for use by all Departments and Agencies of the Department of Defense. 2. This standard is in compliance with the Acquisition Reform Initiatives of Dr. William Perry’s memo dated 29 June 1995 (see 6.8). 3. This standard contains two sections, the main body and an appendix. The main body of the standard specifies a baseline set of requirements. The appendix portion provides rationale, guidance, and lessons learned for each requirement to enable the procuring activity to tailor the baseline requirements for a particular application. The appendix also permits government and industry personnel to understand the purpose of the requirements and potential verification methodology for a design. The appendix is not a mandatory part of this document. 4. A joint committee consisting of representatives of the Army, Navy, Air Force, other DoD Agencies, and industry participated in the preparation of this standard. 5. Comments and data which may be of use in improving this document should be addressed to: USAF/Aeronautical Systems Center, ASC/ENSI, 2530 Loop Road West, Wright Patterson AFB, OH 45433 7101, by using the Standardization Document Improvement Proposal (DD Form 1426) appearing at the end of this document or by letter. iiMIL STD 464 CONTENTS Paragraph Page FOREWORD ......................................................................................... ii 1.
