No specification found for this NSN.
An item used specifically to perform functions such as controlling, protecting, measuring and switching for fire control systems. May include such items as switch units, switches, variable resistors, relays, meters, fuses, synchro overload indicating devices, terminal boards and wiring and may be sectionalized. (for the purpose of this definition a section is defined as a self-contained structure mounted on a common base consisting of a complete framework with all required inclosures.)
Indicates that the item represented by the nsn in the input/output header is the replacement for and is interchangeable with the item in the segment h. The replacement item will not be issued until the supply of the replaced item is exhausted. Must be used in combination with phrase code e.
OOU: Order of Use. Three position alpha code denoting the interchangeability and substitutability (I&S) relationship of a national stock number within a service/agency I&S family.
JTC: Jump to Code. Three position alpha code that denotes an exception to the normal sequence to be followed in the attrition of items within an interchangeability and substitutability (I&S) family.
Phrase Code: A one position code assigned to a phrase used in the management data list to denote changes and/or relationships between national stock numbers and reference data.
Indicates there is no data in the hmirs and the nsn is in a fsc not generally suspected of containing hazardous materials.
Item does not contain precious metal.
No known electrostatic discharge (esd) or electromagnetic interference (emi) sensitivity.
Represents items with no adp components
The item does not have a nuclear hardened feature or any other critical feature such as tolerance, fit restriction or application.
HMIC: Hazardous Material Indicator Code. A one position code that identifies a hazardous item.
PMIC: Precious Metal Indicator Code. A one position code which identifies items that have precious metals as part of their content. precious metals are those metals generally considered to be uncommon, highly valuable, and relatively superior in certain properties such as resistance to corrosion and electrical conductivity.
ESD: Electrostatic Discharge. Indicates if an item is susceptible to electrostatic discharge or electromagnetic interference damage. electrostatic discharge damage occurs when an accumulation of static electricity generated by the relative motion or separation of materials is released to another item by direct contact. electromagnetic interference damage occurs when an item comes into proximity with an electrostatic or magnetic field.
ENAC: Enviromental Attribute Code. Identifies items with environmentally preferred characteristics.
CRITL: Criticality Indicator Code. Indicates an item is technically critical by tolerance, fit, application, nuclear hardness properties, or other characteristics.

SOS: Source of Supply. A three position code or routing identifier code (ric), which identifies the source of supply activity.
SMIC: Special Material Indicator Code. A two position code, which categorizes material on the basis of requirements for source or quality control, technical design or configuration control, procurement, stocking and issue control, special receipt, inspection, testing, storage, or handling.
MMAC: Material Management Aggregation Code. A two position code that identifies an item of supply to be managed by a specific activity manager.
MCC: Material Echelon Code. A two position code employed by the marine corps in classifying items into categories by materiel category and procurement echelon. the alphanumeric management code is in the first position and identifies the materiel category
IMC: Denotes wether items shall be subjected to integrated management under the defense supply agency or retained by the individual military service or other department of defense components for their management. Assigned by th activity responsible for item management coding.
