E-MAIL: Marolyn S. Cross, mscross@pop500.gsfc.nasa.gov. NASA/GSFC plans to issue a Request for Quotation (RFQ) for 12 burst discs, with a 325 wire mesh inlet and a 250 X 1400 mesh outlets. This procurement is being conducted under the Simplified Acquisition Procedures (SAP). NASA/GSFC intends to purchase the items from Hydrodyne, a Division of FPI, 3125 Damon way, Burbank, CA 91505. Hydrodyne is the only vendor that can provide a compatible burst disc that can meet all the required volume, mass, and pressure differential specifications defined by the GLAS Flight Laser transmitter. Therefore, no other burst disc will satisfy Agency requirements at this time. The burst discs are intended for GLAS Spaceflight application and Hydrodyne's traceability and heritage are important factors. It has been established, through past experience, that the Hydrodyne burst disc design is of the highest quality and reliability, which is critical to the survival of the flight laser transmitter during environmental testing, as well as on-orbit operation. The burst disc is required for compatibility with the existing flight laser hardware and instrument interfaces. Specifications: Rupture pressure: 7.5 PSID +/-1.5 PSI; Rupture temperature: 20 degrees C; Operating temperature: -30C to +50C; Assembly shall withstand back pressure of 18 PSID Min; Fluid media: N2 Vendor shall ATP and cleaning to level 100 per MIL-STD-1246 on internal surfaces.
