Identification Item Identification Guide (IIG) and Item Name Code (INC)
Definition Definition of approved item name (AIN): "WASHER,RECESSED"
A washer of any peripheral shape having a centrally located hole. Both bearing surfaces are parallel and flat, but one or both of the bearing surfaces must be broken by a counterbore, countersink, or similarly shaped recess. The thickness must not exceed 25 per cent of the outside diameter or the largest outside dimension. The maximum limit of the tolerance or range applied to the thickness and/or largest outside dimension must be used to determine compliance. Excludes washer, concave, retainer, packing, and thrust type washers. See also spacer, sleeve; and spacer, stepped.
5310-01-261-1913 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.
Precious metal content is unknown
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.
