This standard, along with ASME Y14.100M, establishes the essential requirements and reference documents applicable to the preparation and revision of engineering drawings and associated lists for or by Departments and Agencies of the Department of Defense. ASME Y14.100M is the preferred requirements document for engineering drawing practices. This standard should only be used in lieu of ASME Y14.100M where the necessity for a DoD design activity is fully justified and Government logistics support is required.
