A binary counting unit used to electronically count the quantity of discrete electrical impulses applied to its input terminal. It is normally used in conjuction with other counting units in a counter, electronic, digital readout. The unit is designed to count from zero to a predetermined digit, return to zero, and simultaneously generate an output signal for applications as required, such as to other counting units, meters, or remote indicators. It may be a plug-in or circuit card unit of vacuum tube or transistorized design. It may be nonindicating or indicating with display in the form of vertical, horizontal, in-line, or remote readout. Excludes counter, electrical; counter, electronic, digital; and counter, electronic, digital readout. See also indicator, digital display.
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.
