Only written requests for copies of the solicitation will be accepted via mail or fax at (216) 433-8851. Requests shall include the solicitation no. RFQ 152-6 and your company's name, phone no., and mailing address. 1) 4.00% H2, 20.17% O2, 75.83% N2; 2) 3.75% H2, 20.22% O2, 76.03% N2; 3) 3.45% H2, 20.28% O2, 76.27% N2; 4) 3.35% H2, 20.30% O2, 76.35% N2, 5) 6.00% H2, 12.00% O2, 82.00% CO2; 6) 5.17% H2, 10.33% O2, 84.50% CO2; 7) 4.67% H2, 9.33% O2, 86.00% CO2; 8) 4.33% H2, 8.67% O2, 86.00% CO2; 9) 7.67% H2, 15.33% O2, 77.00% SF6; 10) 7.17% H2, 14.33% O2, 78.50% SF6; 11) 6.67% H2, 13.33% O2, 80.00% SF6; 12) 6.33% H2, 12.67% O2, 81.00% SF6; 13-16 Same as test points 9-12. 17) 11.00% CH4, 22.00% O2, 67.00% SF6; 18) 10.50% CH4, 21.00% O2, 68.50% SF6; 19) 10.33% CH4, 20.67% O2, 69.00% SF6; 20) 10.00% CH4, 20.00% O2, 70.00% SF6. All compositions are % volume. All mixtures must be accurate to within 2% of each component's composition (example -4.00% +/-0.04%) and must be verified through two analysis. The pressures shall be 320 PSIA (test points 1-4), 350 PSIA (test points 5-8), 180 PSIA (test points 9-16), and 160 PSIA (test points 17-20). These pressures are low for safety and liquification reasons. The delivered amounts shall be a minimum of three bottles of each test point to NASA-Lewis Research Center in Cleveland, OH, and three bottles of each test point to NASA-Kennedy Space Center at Cape Canaveral, FL. Acceptance of gas mixtures will be dependent on verification of bottle contents by independent gas composition analysis performed by LeRC personnel. The option for more deliveries is possible. Bottles will be standard 225 scf gas cylinders with CGA 350 connections. Delivery dates are estimated to be from January 1, 1996 for NASA-LeRC and March 1, 1996 for NASA-KSC.

Effective October 1, 1995, the Internet will be the only source of NASA Lewis Research Center MidRange synopses and solicitations. Other synopses will continue to be published in the CBD as well as the Internet. Internet Address: http://www.lerc.nasa.gov/Other_Groups/Procure/home.htm (298)
