MIL-STD-100GFOREWORD1. This Military Standard is approved for use by all Departments and Agencies of the Departmentof Defense (DoD).2. Beneficial comments (recommendations, additions, deletions) and any pertinent data which maybe of use in improving this document should be addressed to: Commander, U.S. Army ArmamentResearch, Development and Engineering Center, ATTN: AMSTA-AR-EDE-S, Picatinny Arsenal,NJ 07806-5000, by using the Standardization Document Improvement Proposal (DD Form 1426)appearing at the end of this document or by letter.3. The preferred standard for Engineering Drawing Practices is ASME Y14.100M. Thecontractual application of MIL-STD-100 is permissible provided one or both of the followingconditions exist: it is required and fully justifiable that a DoD activity be the design activity the applicable end item requires Government logistics support4. This Military Standard provides:a. Standard practices for the preparation of engineering drawings, drawing format and media fordelivery.b. Requirements for drawings derived from or maintained by Computer Aided Design (CAD).c. Procedures for the creation of titles for engineering drawings.d. Numbering, coding and identification procedures for engineering drawings, associated listsand documents referenced on these engineering drawings and associated lists.e. Locations for Marking on engineering drawings.5. The policy of the DoD is to utilize to the maximum degree possible those non-Governmentstandards which satisfy the needs of the military. Accordingly, this standard will be revisedperiodically to take advantage of those non-Government standards which meet the DoD criterionfor technical sufficiency.Similarly, and in keeping with the DoD practice of adopting non-Government standardswhenever practicable, Chapters 600 and 700, as contained in previous versions of MIL-STD100, have been entirely replaced by ASME Y14.35M and ASME Y14.34M respectively, andChapter 200 is largely based on ASME Y14.24M. An accurate perception of DoDEngineering Drawing Practices therefore necessitates user recognition of MIL-STD-100G,ASME Y14.24M, ASME Y14.34M, ASME Y14.35M, and ASME Y14.100M as being acomposite set.6. Fundamental to the current content and maintenance of MIL-STD-100 is the existence of theDOD/Industry Drawing Practices Group (DRPRG). The DRPRG is chartered under the DefenseStandardization Program as a cooperative effort between DOD and Industry directed towardcodifying and standardizing engineering documentation practices, promoting applicable nonGovernment standards, and fostering liaison between industry associations and Governmentii

MIL-STD-100Gagencies. The DRPRG addresses the entire range of issues from the current status and neededchanges to MIL-STD-100, to electronic data storage and transmission, and the ongoingrequirement for compatibility with initiatives associated with Continuous Acquisition and Life CycleSupport (CALS).7. The DRPRG is chaired by the DOD Lead Standardization Activity (LSA) for DRPR and is cochaired by an industry association member. The Office of the Assistant Secretary of Defense forProduction and Logistics provides management oversight through its representative who serves asExecutive Liaison. The DRPRG meets three or four times a year to address issues brought beforeit. For more information on the DRPRG and its proceedings please contact the DRPR LSA,located at the address indicated above for beneficial comments.iii
