MIL-STD-100 Engineering Drawings S/S By Asme-Y14.100, Asme-Y14.24, Asme-Y14.35M, And Asme-14.34MThis 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

CHAPTER 300

DRAWING TITLES

300.  General. This chapter establishes procedures for creating titles for engineering drawings and names for items detailed thereon.

301.  Drawing title.  The drawing title shall be the name by which the part or item will be known and shall consist of a basic item name, Government type designator, if applicable, and sufficient modifiers to differentiate like items in the same major assembly.   Reference to major assemblies

or end items shall not be included as part of the drawing title for subassemblies and parts except when necessary to differentiate such items from similar items.

301.1  Approved item names.  Approved item names are those item names listed in Cataloging Handbook H6, Federal Item Name Directory for Supply Cataloging.  Approved item names are preferred for use in drawing titles.  Item names not listed in H6 should be submitted, through the Government design or procuring activity, to the Defense Logistics Services Center (DLSC) for approval.

301.2  Type designators.  Type designators, a combination of letters and/or numbers assigned by the Government for the purpose of item identification, are assigned in accordance with approved type designator - nomenclature systems such as:

Joint Electronics Type                                MIL-STD-196

Designation System

Army Nomenclature System                      MIL-STD-1464

Mark and Mod Nomenclature                    MIL-STD-1661

System

Type Designation, Assignment                  MIL-STD-1812 and Method of Obtaining

301.3  Assembly.  The term ASSEMBLY when used as a part of the drawing title shall conform to the definition contained in 3.7 and meet the requirements of Cataloging Handbook H6.

302.  Procedures for creating drawing titles.  Titles for drawings requiring modifiers shall be in two parts.  The first part shall be the name.  The second part shall consist of those additional modifiers and Government type designators necessary to complete the identification of the item.

302.1  General rules.  The following rules apply to all drawing titles:

a.  No abbreviations of any portion of the name (first part of the title) shall be made, except those necessarily used trademarked names and the words ASSEMBLY (ASSY), SUBASSEMBLY (SUBASSY), or INSTALLATION (INSTL).  Abbreviations may be used in

the second part of the title.  Approved abbreviations are listed in ASME Y1.1.  In general, the use of abbreviations should be avoided.

b.  Titles of subassembly and detail drawings shall be consistent with the titles of the next assembly drawings, except where interchangeability of parts between assemblies makes
