round, flat
An insulator that is essentially thin and flat, with one through hole centrally located. The general shape may vary by the addition of features such as beveled edges, indented surfaces, through hole keys, and/or peripheral flats. The thickness measured between the two parallel bearing surfaces must not exceed 25 percent of the outside diameter or the shortest distance between peripheral flats. The thickness measured between the two parallel bearing surfaces must not exceed 25 percent of the outside diameter or the shortest distance between peripheral flats. Excludes items with more than one hole. See also insulator, disk; insulator, bead; insulator, bushing; and insulator, plate
Indicates that the item represented in the input/output header is the preferred replacement item master nsn in the i&s family and is suitable for the item(s)in segment h. use the item represented by the nsn in segment h if technically acceptable for your specific application. the replacement item, master nsn in the i&s family, will be issued when the supply of the replaced item(s) is exhausted. must be used in combination with phrase code f.
OOU: Order of Use. Three position alpha code denoting the interchangeability and substitutability (I&S) relationship of a national stock number within a service/agency I&S family.
JTC: Jump to Code. Three position alpha code that denotes an exception to the normal sequence to be followed in the attrition of items within an interchangeability and substitutability (I&S) family.
Phrase Code: A one position code assigned to a phrase used in the management data list to denote changes and/or relationships between national stock numbers and reference data.
Indicates there is no information in the hmirs. The nsn is in a fsc in table ii of fed std 313 and a msds may be required by the user. The requirement for a msds is dependent on a hazard determination of the supplier or the intended end use of item.
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.
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.
