MIL-HDBK-237C, DEPARTMENT OF DEFENSE HANDBOOK: ELECTROMAGNETIC ENVIRONMENTAL EFFECTS AND SPECTRUM CERTIFICATION GUIDANCE FOR THE ACQUISITION PROCESS (17 JUL 2001)., This handbook provides acquisition personnel responsible for the design, development, and procurement of Department of Defense (DoD) platforms/systems and subsystems/equipment with the guidance necessary for achieving the desired level of electromagnetic (EM) compatibility (EMC). This handbook describes the tasks that should be accomplished to ensure electromagnetic environmental effects (E3) control and spectrum certification (SC) procedures are addressed during the item’s acquisition life cycle. This handbook is consistent with the policies and procedures of DoD Directives (DoDD) 5000.1, 3222.3, and 4650.1, DoD Instruction (DoDI) 5000.2, and DoD Regulation (DoDR) 5000.2-R. Provisions of this handbook should be used by research, development and acquisition activities, at appropriate times during the life cycle of any item which emits or which can be susceptible to electromagnetic energy either through intentional antennas or through other electromagnetic coupling mechanisms. Essentially, all electronics items and many electrical items fall into this classification. For example, the handbook may be used: - During acquisition to assure visibility, accountability, and controllability of the E3/SC effort, as well as its integration into the overall program, or - During the design process to assure management awareness and cost effective tailoring of applicable E3 performance requirements and interface standards. This handbook is for guidance only. This handbook cannot be cited as a requirement. If it is, the contractor does not have to comply.

Title:Aircraft Flotation Analysis
Issuing Committee:A-5 Aerospace Landing Gear Systems Committee
Scope: This document is divided into five parts. The first part deals with flotation analysis features and definitions to acquaint the engineer with elements common to the various methods and the meanings of the terms used. The second part identifies and describes the various methods used. To accomplish the minimum intent of this document, techniques could be limited to those needed for flotation analysis only; however, because of the close relation between flotation analysis and runway design, methods for the latter are also included. In fact, runway design criteria are used for flotation and evaluation in some cases, and are periodically the governing procedure in specific, if isolated, instances. From time to time, it may be necessary to deal with runways built to obsolete criteria. Therefore, a listing of most of these constitutes the third part. The fourth part of this document tabulates the recommended documents, categorizing them for commercial and civil versus military usage, by military service to be satisfied, and by type of pavement. The document concludes with brief elaborations of some concepts for broadening the analyst's understanding of the subject.【英文标准名称】:Testingmethodforgrainsizeofcoatedabrasivemacrogrits(P12-P220)
