It is important to have a clear understanding of the
terms used in the material identification process. The
following terms are used in this process:
MATERIALrefers to supplies, repair parts,
equipment, and equipage used in the Navy.
EQUIPMENTany functional unit of hull,
mechanical, electrical, ordnance, or electronic-type
material, It operated by itself or as a component of a
system or subsystem. Equipment is identified by a
component identification number (CID), numerical
control code (NCC), allowance parts list (APL), or
SUPPORT EQUIPMENTis equipment such as
test equipment, fixtures, hand tools, etc., required for
the maintenance, assembly, disassembly, overhaul,
repair, and test or check of an end item of equipment.
EQUIPMENT DIVISIONThe standard terms
that describe the breakdown of electrical, electronic,
mechanical, pneumatic, and hydraulic military
equipment. They are explained as follows
Partone or more pieces joined together.
Normally, disassembly prevents them from
being used as designed (e.g., outer front wheel
bearing of a truck, an electron tube, a
Subassemblyis two or more parts which form
a portion of an assembly or a unit that can be
replaced as a whole. It may have a part or parts
that can be individual y replaced (e.g., gun
mount stand, window sash, recoil mechanism,
floating piston, telephone dial, terminal bead
with mounted parts).
Assemblya number of parts, subassemblies
or any combination, joined together to perform
a specific function (e.g., power shovel front, fan
assembly, audiofrequency amplifier). The
distinction between an assembly and a
subassembly is not always exact. An assembly
in one instance maybe a subassembly in another
(i.e., when it forms a portion of an assembly).
Unitan assembly or any combination of parts,
subassemblies, and assemblies mounted
together, normally capable of independent
operation in a variety of situations (e.g.,
hydraulic jack, electric motor, electronic power
supply, internal combustion engine, electric
generator, radio receiver). The size of an item is
a consideration in some cases. An electric motor
for a clock may be considered as a unit, because
it is not normally disassembled.
Groupa collection of units, assemblies, or
subassemblies which is a subdivision of a set or
system. It is not capable of performing a
complete operational function (e.g., antenna
group, indicator group).
EQUIPAGEitems which require management
control afloat because of one or more of the following
High unit cost
Vulnerability to pilferage
Essential to the ships mission
Equipage does not include installed mechanical,
electrical, ordnance, or electronic equipments,
components, or systems. Equipage items are usually
identifiable to an end-use application aboard a ship.
Allowed quantities of the item are determined on an
individual ship basis. Chargeable items of equipage are
identified in procurement, receipt, and consumption
documents by the letter E in the second position of
the applicable fund code. (See NAVSO P-3013.)
Controlled Equipageto those items of
equipage that require special management
control because the material is:
essential for the protection of life, or
relatively valuable and easily convertible to
Controlled equipage (e.g., life preservers, gas
masks, binoculars, and firearms) is usually carried on
board in allowance quantities only, and require special
inventory control in accordance with NAVSUP P-485.
Equipment and Equipage Replacements Funded
by a Type Commander as Controlled
Equipagedurable, high priced, and essential
items of equipment and equipage not designated
as controlled equipage. These are normally
replaced during a ships regular overhaul only.
Replacement of such items as anchors, shots of
chain, chain stoppers, binnacles, pelorus, and
laundry equipment during a regular overhaul,
are chargeable to overhaul funds. If replacement
of these items is required between overhauls an
OPTAR augmentation is normally requested
from the type commander.
REPAIR PARTany item, including modules and
consumable-type materials, which has an equipment
