B -- TEST THERMAL CONDUCTIVITY SOL RFQ3-115322 DUE 011599 POC Jon C. Schultz, Contract Specialist, Phone (216) 433-2764, Fax (216) 433-2480, Email Jon.C.Schultz@lerc.nasa.gov WEB: Click here for the latest information about this notice, http://nais.nasa.gov/EPS/LeRC/date.html#RFQ3-115322. E-MAIL: Jon C. Schultz, Jon.C.Schultz@lerc.nasa.gov. THIS NOTICE CONSTITUTES AMENDMENT NO. 1 TO THE COMBINED SYNOPSIS/RFQ FOR " Test Thermal Conductivity ". Companies shall acknowledge all amendment(s) in their quote. This notice serves as the official amendment to subject synopsis/RFQ and a written amendment will not be issued. The purpose of this amendment is to revise the specifications for Items 1 and 2 as follows: Revised Item 1: Test Thermal conductivity of Cu-Cr-Nb alloys from minus 196 degrees C (liquid nitrogen) to room temperature using the Kohlrausch technique. Include an estimate of the thermal conductivity between liquid nitrogen and liquid hydrogen.Temperatures are to remain the same as the original specifications. -- Revised Item 2: Test thermal conductivity of Cu-Cr-Nb alloys from room temperature to 900 degrees C using the laser flash technique. Also supply the thermal diffusivity and heat capacity with the thermal conductivity. Temperatures are to remain the same as the original specifications. NOTE: If the original specifications for Item 1 read,in part, "Item 1 -- Cryogenic Conductivity: Thermal diffusivity testing shall be conducted from 200C 1150C to -- -2000C 1250C (liquid nitrogen temperature) " then other numeric specifications are probably incorrect also. Please contact the primary contact, Jon C. Schultz at 216-433-2764 or at Email: Jon.C.Schultz@lerc.nasa.gov. A correct, printed copy of the original specifications will be faxed to you. The due date for receipt of offers is not extended. Companies shall provide the information stated in the synopsis/RFQ posted on the NASA Acquisition Internet Service (NAIS) on 12-31-98. Documents related to this procurement are available over the Internet and are in Microsoft Office Suite (Word 6.0, Excel 5.0, or PowerPoint 4.0) format and reside on the World Wide Web (WWW) server which may be accessed using a WWW browser application.
