About this file
This document provides a test verification summary for propellant tanks to be used on the Roman Space Telescope project. The summary outlines the inspection, analysis, and test requirements that will be used to qualify the propellant tanks according to the performance specifications. These include requirements for maximum expected operating pressure, proof pressure testing, burst pressure testing, minimum internal pressure, differential pressure capabilities, interface tube proof and burst pressures, external and internal leakage rates, expulsion efficiency, leak before burst, diaphragm cycling, mass properties, mechanical interfaces, cleanliness, contamination control, materials, safety, identification and marking, workmanship standards, design life, handling and transportation, and factors of safety. Tests identified include quasi-static acceleration testing, fundamental frequency analysis, sine and random vibration testing, shock testing, pressure testing, temperature testing, and lift point proof testing. Successful completion of this verification and test program will be required to accept the propellant tanks for use on the Roman Space Telescope.
