(PMIC) Precious Metals Indicator

Precious metal content is unknown

What does the U code means?

Precious metals indicator code (pmic): this code is to identify items that have precious metals as part of their content. Precious metals are those metals generally considered to be uncommon and highly valuable which are relatively superior in certain properties such as resistance to corrosion and electrical conductivity. The precious metals recovery program for the federal government encompasses gold, silver, platinum, and the platinum family which consists of palladium, iridium, rhodium, osmium, and ruthenium. See volume 10, table 160 and quick info on-line.

(HMIC) Hazardous Metal Indicator

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

What does the N code means?

Hazardous materials indicator code: a code established in the dlis total item record (tir) to identify to users of the federal catalog system all known or suspected hazardous items as defined by safety/health, transaction and/or environmental regulations, to serve as a flag that a procuring activity must acquire a material safety data sheet when a hazardous item is procured, and to inform federal catalog system users when more detailed information on an item is available in the hazardous material information system. See volume 10, table 179 and quick info on-line.

Criticality Code

The item does not have a nuclear hardened feature or any other critical feature such as tolerance, fit restriction or application.

What does the X code means?

Criticality code, federal item identification guide: a code which indicates when an item is technically critical, by reason of tolerance, fit, application, nuclear hardness properties or other characteristic which affects identification of the item. See volume 10, table 181 and quick info on-line.
