INDEX CONCLUDING MATERIAL Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-HDBK-454B 1 1. SCOPE 1.1 Guidelines

23、 applicable to electronic equipment. This handbook provides guidance and lessons learned in the selection of documentation for the design of electronic equipment. This handbook is for guidance only and cannot be cited as a requirement. If it is, the contractor does not have to comply. 1.2 Revision o

24、f guidelines. Revisions of individual guidelines are indicated by a date below the guideline number located at the bottom of the page. When the basic document is revised, those guidelines not affected by change retain their existing date. 1.2.1 Redating. Although individual guidelines are reviewed a

25、nd updated or validated at least once every eighteen months, guidelines are not redated unless technical changes are made. 1.3. Method of reference. Guidelines contained herein should be referenced by specifying this handbook and the guideline number for guidance only. 1.4 Interrelationship of guide

26、lines. Each guideline is intended to cover some discipline in the design of equipment, such as a procedure, a process, or the selection and application of parts and materials. Many of these disciplines, however, cannot retain a clear-cut separation or isolation from others so that when guidelines of

27、 MIL-HDBK-454 are referenced in a specification some guidelines will undoubtedly have a direct interrelationship with other guidelines. This interrelationship should be taken into consideration when referencing these guidelines. 2. APPLICABLE DOCUMENTS. 2.1 Individual guidelines. See section 2 of ea

28、ch individual guideline for a listing of applicable documents. Documents referenced in the individual guidelines apply to the extent specified herein.
