A -- RESEARCH AND REPORTS ON METHODS AND DATA FOR VAPOR PRESSURES AT VERY HIGH TEMPERATURES SOL 53SBNB067094 DUE 093000 POC Sharon Blue, Contract Specialist e-mail sharon.blue@nist.gov, (301) 975-8831, e-mail sandra.febach@nist.gov, Sandra Febach, Contracting Officer (301) 975-6326. WEB: NIST Contracts Homepage, http://www.nist.gov/admin/od/contract/contract.htm. E-MAIL: NIST Contracts Office, Contract@nist.gov. The National Institute of Standards and Technology (NIST) intends to negotiate with John Hastie, 19405 Faber Ct., Gaithersburg, MD 20886, on a sole source basis to perform complete evaluation and documentation of a unique measurement methodology designed by John Hastie to obtain materials vapor pressure and temperature data at very high temperatures. Deliverables will include: (1) interpretation of data on vaporization rates and temperatures for refractory materials, such as Hf02, Zr02, and Y203 over melting to boiling point temperature range. (2) Evaluate the influence of ionization cross section uncertainties on mass spectrometrically determined partial pressures and related thermochemical functions for high temperature systems. (3) Investigate and test new experimental and theoretically based approaches to cross section determinations. (4) Interpret, evaluate, and document new experimental approaches, developed at NIST, to the measurement of pressure and temperature at very high temperatures beyond 3000 Celsius. This acquisition is to be accomplished under the authority of FAR 13.106-1 (b) Only one source reasonably available. The Contractor has demonstrated unique qualifying experience with research of methods for vapor pressures at very high temperatures. Award to another source would result in substantial duplication of cost to the Government that is not expected to be recovered through competition, and would result in unacceptable delays in fulfilling the agency's requirements. It is anticipated that a Firm Fixed Price (FFP) purchase order will be awarded by October 1, 2000. Expected period of performance is from October 1, 2000 through September 30, 2001. The Standard Industrial Classification code (SIC) is 8732. This notice of intent is not a request for competition. However, the Government will consider all responses received within 15 days after the date of publication of this synopsis. Written responses to this synopsis shall contain sufficient documentation to establish a bonafide capability to fulfill the requirement. A solicitation is not available. Posted 08/16/00 (W-SN486979).
