Identification Item Identification Guide (IIG) and Item Name Code (INC)

Definition Definition of approved item name (AIN): "SEPARATOR,WATER,AIRCRAFT AIR CON"

An item which separates free moisture or water vapor from the compressed airstream in an aircraft air conditioning system after it is discharged from a cooling turbine. Provides moisture free air for cabin and/or compartments. Normally consists of a cylindrical or oval shaped shell with an inlet and outlet port and a drain port, a cylindrical, rectangular or conical shape condenser, and a device to collect the moisture after it leaves the condenser. May include an internal bypass valve. Generally consists of two types: (1) the condenser-eliminator type which collects the moisture on a tubular type core after it leaves the condenser and runs to the bottom and drains out; (2) the swirl type causing the moist air to swirl rapidly as it leaves the condenser throwing the moisture against the shell where it collects and runs down to drain.

  Identification Codes

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.

Material Management Material categorization and source of supply

  Material Codes

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.
