52 -- RUSKA AIR PISTON GAGE SYSTEM SOL IFB5-18421/604 DUE 061595 POC Richard M. Swanson/Contracting Officer, 804/824-1426. Air Piston Gage System, Ruska Model Number 2465-630 (1 each), with AutoPrompt Converter, Ruska Model Number 2411 (1 each), and High Pressure Air Piston Gage System, Ruska Model Number 2475 (1 each). The Sounding Rocket Program uses Ruska air piston gages to generate state-of-the-art accurate gage/absolute calibration pressures on flight critical hardware. Only the Ruska models indicated possess (as a compatible system) the low temperature coefficient design, oil free operation, environmental factors offsets, trim mass offsets, reference volume and portability requisite to performing optimum program calibration functions. They exclusively also utilize helium as the pressure medium to preclude drawing contaminants from the metal lining of the system. The presence of such contaminants could cause an explosive hazard to the gage users. This is a notice of intent to issue Invitation For Bids (IFB)5-18421/604 to a limited number of responsible sources in accordanace with 10 U.S.C. 2304 (c)(1), ''Only One Responsible Source,'' and Federal Acquisition Regulation (FAR) 6.302-1(a)(2).
