Identification Item Identification Guide (IIG) and Item Name Code (INC)
Definition Definition of approved item name (AIN): "GEAR CLUSTER"
A cylindrical item having a full 360 degree (6.282 radians) complement of teeth on two or more surfaces. It may be a one-piece casting or composed of two or more separate items firmly held together by welding, rivets, pins, or the like, to form a single unit. It is designed to mount on a shaft. For items consisting of a shaft with an integral complement(s) or gear teeth, see gearshaft (as modified). Excludes gear subassembly, speed decreaser.
3020-01-246-5238 Material Hazmat, Precious Metals, Criticality, Enviroment, and ESD
Indicates there is no data in the hmirs and the nsn is in a fsc not generally suspected of containing hazardous materials.
Item contains silver.
The item does not have a nuclear hardened feature or any other critical feature such as tolerance, fit restriction or application.
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.
