Definition Definition of approved item name (AIN): "CHRONOMETER"

An instrument for precisely determining time, manufactured to close tolerances to assure the time-keeping qualities of dependability and consistency of rate. These qualities are accurately ascertained by comparison with more exact devices or by astronomical methods so that the accumulated error may be taken into account when determining time. Its usual uses are to indicate time for navigational purposes, and to serve as a reference for less accurate timepieces. It is usually provided with a winding indicator dial and is usually mounted in gimbals to maintain the instrument in a level position. May consist of a spring driven or other type of movement which is capable of exacting performance without regulation throughout the normal range of room temperatures. Not designed for carrying on the person.

Hazmat (HMIC) N

Indicates there is no data in the hmirs and the nsn is in a fsc not generally suspected of containing hazardous materials.

Precious Metals (PMIC) U

Precious metal content is unknown

Criticality X

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.
