5810-99-390-9930 5810993909930 993909930 is an item or group of items employed to modify communication, detection, and coherent radiation equipment. excludes data transmission, terminals, sensors and other devices designed for use with adpe.

4130-12-390-9930 4130123909930 123909930 is a replaceable device designed to remove dust, pollen or other foreign matter from the air passing through it. the removal of particles is accomplished by porous fibrous or shredded material (metallic or nonmetallic) which is loosely woven or matted and confined in a frame or retained between perforated sheets of firmer material. it is designed to fit into air conditioners, ventilation systems and hot air furnaces. it may have facilities for radio frequency/electromagnetic interference shielding. the filter may be cleaned by the use of compressed air, blown through the filter element, or by using water and a suitable detergent for cleaning purposes which would extend the life of the filter.

5340-14-390-9930 5340143909930 143909930 is a standoff that must have a threaded end(s) or be internally threaded its full length. for items having external threads on both ends, see stud (as modified). for items with an outside contour that is the same for the entire length, are flat on top and bottom, having internal threads its full length, and the length does not exceed twice the width across the flats or outside diameter, see nut (as modified); use maximum dimensions(s) for compliance.

7195-01-390-9930 7195013909930 013909930 is an item of furniture which offers sight barriers and a limited degree of sound dampening. it is insulated and is not designed to be permanently installed. it may have a flat base; removable feet; or casters. also it is not a room-dividing partition similar to standard "bank-type" partitions. excludes screen, bedside and screen, folding.

5905-00-390-9930 5905003909930 003909930 is a resistor whose ohmic value cannot be adjusted or varied. the resistance element consists of either a thin layer of conductive material, containing either binders or insulating materials, deposited on an insulated form; or an alloy of metal and ceramic materials, usually fused to an insulated form. opposition to the flow of current is an inherent property of the materials used and is manifest by the heat dissipation in the resistor. see also attenuator, fixed and resistor, fixed, composition. excludes carbon composition type resistors.
