Revisions of individual guidelines are indicated by a date below the guideline number locatedat the bottom of the page. When the basic document is revised, those guidelines not affected by change retain their existingdate.1.2.1 Redatino. Although individual guidelines are reviewed and updated or validated at least once every eighteen months,guidelines are not redated untess technicat changes are made.1.3. Nethod of reference. Guidelines contained herein should be referenced in the individual specification by specifying thishandbook and the guideline number.1.4 Interrelationship of guidelines. Each guideline is intended to cover some discipline in the design ofas a procedure, a process or the selection and application of parts and iaterials. Many of these disciplines,retain a clear-cut separation or isolation from others so that when guidelines of NIL-HDBK-454 are referenced insome guidelines will undoubtedly have a direct interrelationship with other guidelines. This interrelationshipinto consideration when invoking or using these guidelines.equipment, suchhowever, cannota specificationshould be taken2.
