66 -- DEVELOPMENT WORK FOR THE VERY LOW PRESSURE PRIMARY STANDARD PROJECT POC Carol Neeley, Contract Specialist, OP-ESO-A, 407=867-3406 Barton Scott, Contracting Officer. The contractor shall develop for NASA a Very Low Pressure Primary Standard (VLPPS) with National Institute of Standards and Technology (NIST) traceability. It must meet requirements for range and accuracy in both the absolute and gauge modes, and it shall be capable of testing very low pressure instrumentation to the vendor assigned specifications. Development shall be performed over a period of three years. Task descriptions will be developed for each phase of the project. All hardware, software, source code, training, documentation, and reports will be provided by the contractor. The VLPPS must meet the following requirements: 1. Range: Absolute zero to 1.0 psi (6.9 kPa), may be adjusted somewhat higher. 2. Accuracy: Less than +\- 0.005% of reading or better. 3. Mode: Absolute and gauge mode of operation. Capability as a passive measuring device and as a pressure controller. 4. Resolution: 0.001 In H2O (0.25 Pa) or better. 5. Compact design - Estimated Dimensions +\- 3 cm: Measuring portion: 40 cm deep X 40 cm wide X 75 cm high, Controlling portion: 24 cm deep X 30 cm wide X 16 cm high. Estimated Weight +\- 2 kg: Measuring portion 30 kg, Controlling portion: 15 kg. 6. Hardware consisting of 486DX250VESA, 14'' Super VGA Monitor and 3 1/2'' floppy. 7. Software: Software capable of accounting for all variables associated with the measurement process such as temperature, head corrections, etc., for calculation of measured pressure. Selectable pressure units and documentation required. Source code to be provided. 8. Interface: RS232. 9. User friendly. 10. Operating medium: GN2. 11. Manuals: Operating and Maintenance Manuals including system and component schematics and specifications. Software manuals where appropriate. 12. Certifications: Initial Calibration Certificate with NIST traceability. 13. Training: On-site training at KSC. 14. Installation: On-site systems installation and software set-up at KSC. 15, Reports: Monthly and final reports. DH Instruments, Inc., is the only known source capable of delivering a very low pressure primary standard based on piston-gage principles with all of the features required. DH Instruments unique experience in the design and fabrication of 14 piston/cylinder sizes forms the basis for development of a VLPPS of unequaled performance capability for maximum range and resolution necessary to assure accurate testing of low pressure instrumentation supported by the KSC standards laboratory. The have developed unique fabrication equipment to produce piston cylinder sets and have developed unique designs for mounting of piston cylinder sets. This procurement will be conducted under the NASA Midrange Pilot Test Program approved by the Office of Federal Procurement Policy on April 15, 1993.--Duration of contract: 3 years.--There is no formal solicitation package--All responsible sources may submit a written response, including a description of technical qualifications to this notice which shall be considered by the agency. Responses should be address to NASA, John F. Kennedy Space Center, FL 32899, and must be received no later than 15 days from the date of publication of this notice. (0220)
