DRAWING NUMBERSCertain technical
materials are identified by a drawing or sketch number
assigned by the controlling bureau or systems command
or by the manufacturer, and must appear on all
requisitions when a stock number is not assigned.
JCEC NOMENCLATUREsome items of
electronic equipment are identified by Joint
Communications Electronics Committee (JCEC)
nomenclature (AN/UYK-5(V)) or Navy type
(R-390A/URR) or model number (MK 9 MOD 2) as
well as stock and serial number. In addition, major units
of fire control radar equipment are identified by mark
and modification numbers.
MARK AND MODIFICATION NUMBER
Ordnance material usually is given a mark and
modification number, a drawing number, and a piece
number. These serve to identify the part and facilitate
reference to ordnance publications. Ordnance
equipment may also be serially numbered, giving
individual identify to units that are physically alike.
This number is stamped on certain ordnance equipment,
such as a rifle or pistol to facilitate identification of the
manufacturer and to place responsibility for custody.
TOOLS OF IDENTIFICATION
So far you have studied the need for classifying
material, how material is classified, how the NSN is
constructed, how the NSN is used to classify material,
the types of material used in the Navy, and the various
markings used in identification.
The classification of material as to type is important
because of the method used in accounting for ships
money. This is discussed later in this TRAMAN.
Material identification does not end with the
assignment of a stock number. The customers of the
supply system need some means of identifying their
requirements with the stock numbers assigned to them,
and of detemining the authorized quantities to carry
on bead. Identification of these requirements may be
determined by using the following lists:
Management List-Navy-provides current data
for requisitioning purposes (unit/issue/price,
Allowance Listscontain the items authorized,
and recommended quantities that should be on
hand and provide descriptive data which
associate a material requirement to an NSN.
Load Lists-reflect the range and depth of
material carried by Combat Logistics Forces
(CLF) ships (including tenders and repairships),
or bases to fulfill assigned supply support of fleet
INTRODUCTION TO FEDERAL
SUPPLY CATALOGS AND RELATED
PUBLICATIONS (NAVSUP P-4000)
All Storekeepers should become proficient in the
use of the Introduction to Federal Supply Catalogs and
Related Publications (NAVSUP P-4000) because it
presents a consolidated text of the features and
guidelines for use of various Federal Catalog System
and Naval Supply Systems Command (NAVSUP)
publications. It also presents instructions which
disseminate information relative to items within the
Navy Supply System and indicates the interrelationship
of the various publications.
Complete and accurate management data must be
available for requisitioning purposes and for effective
financial and inventory control of material. The
Management List-Navy (ML-N) provides the basic
management data. Related publications supplement the
ML-N by providing additional management data or by
consolidating certain information for reference
The ML-N and related publications are described
in detail in individual chapters of the NAVSUP P-4000.
Publications covered by this Introduction presents
data using the format of the national stock number
(NSN) and the national item identification number
(NIIN). The short descriptions of what is contained in
each publication should be used as a first step in
obtaining required material identification and
The NAVSUP P-4000 is published by the Navy
Fleet Material Support Office. This publication is not
maintained on a fixed schedule. However, it is updated
by change notices when required, or republished when
the content is revised significantly.
The Management List-Navy (ML-N) is the basic
publication relating to NSN management data. It is
published in NIIN sequence and includes only items for
which Navy interest has been recorded. Ammunition
items are included, but the Catalog of Navy Ammunition
Stock, NAVSEA OD 12067/NAVAIR 11-1-116, is still
essential for ordering and reporting.
