throughout a manual, volumes of a manual, and manuals that are a part of a set of manuals
covering an end item. The preparing activity should develop nomenclature lists for associate

nomenclature should be derived from one of the following sources (listed in the order of
precedence):
a. "AN" nomenclature,
b. Nameplate nomenclature,
c. H-6 assigned nomenclature, or
d. Nomenclature on the drawing from which the item was manufactured.
3.5.3.1.1 Identifying noun modifiers. Modifiers should be arranged in the sequence as
necessary to indicate specifics such as function and location, and to maintain consistency of
nomenclature. Modifiers shall be added to the description of parts as required to assure positive
identification, e.g., washer, flat and washer, lock. These modifiers need not appear on the
preparing activity drawing. For additional information, refer to "Noun modifiers" in
MIL-DTL-81927.

precede the first word in the description column. It is preferred that the symbol be
placed within brackets, that is [HCI] ; however, other methods of highlighting the symbol
to call attention to its importance are acceptable.
