2-23. VOLUME I ILLUSTRATIVE AND IDENTIFICATION DATA
a. Illustrations (graphics) used in this publication are representative and mayor
may not actually depict an item of supply. They are included to aid in the identification
of items displayed in the descriptive section. They appear on the frame directly above
the associated characteristics data. Some item descriptions refer to or require no
illustrations, while others may require one or more, with a maximum of eight possible.
When an applicable drawing for an item description is not provided, the words
"DRAWING IN PROGRESS" will be printed in the space above the item description
where the drawing should have been displayed.
b. Descriptive Data appears immediately following the illustrations and may
appear in a narrative or tabular format, whichever is determined most effective to
display a group of like items. Items are sequenced by FSN, alphabetically by Item
Name within FSC, and by selected descriptive characteristics within Item Name. The
descriptive section includes the following.
(1) Item Name. The item name may appear immediately below the
illustration, as the first entry over the column heading for the descriptive data, or as the
first entry in the item description when the description appears in narrative format only.
(2) Item Number. A sequential number used for indexing purposes to locate
the particular item. Item numbers begins with "01" on each frame.
(3) National Stock Number. The NSN consists of the four (4) digit FSC and
the nine (9) digit NIIN. The FSC appears at the top of each frame. The NIIN is listed on
the left side of the frame.
(4) Item Description. The description is the clear text physical and
performance characteristics data on an item of supply. Those items that have the same
item name and characteristics are grouped together and are called "COMMON
VALUES." The common value statement appears on a line by itself between the tabular
headers and the descriptive data. All items listed below the common value statement
apply to the common value description. When a description is in tabular format, tabular
headers appear at the top of the description and apply to all items listed below the
headers. Additional information is listed in the last column and includes additional
characteristic data, special notes, and the manufacturer's name, address, and other
related data if available. Items that have no tabular headers appear in narrative format.
Items that have not been approved by the DMSB appear in a narrative format with the
