    Abstract

    During the initial stage of the development of propulsion, life support systems, and associated ground support equipment for the U.S. space program, the compatibility of materials for oxygen systems was ascertained via a liquid oxygen impact test that ultimately resulted in ASTM Test Method for Compatibility of Materials with Liquid Oxygen (Impact Sensitivity Threshold and Pass-Fail Technique) (D 2512). After the Apollo 204 fire, the National Aeronautics and Space Administration (NASA) developed improved flammability tests for materials used in the crew areas of manned spacecraft and pressurized mechanical and pneumatic impact tests for materials used in high pressure flight and ground systems. The NASA Headquarters subsequently published a handbook, NHB 8060.1, “Flammability, Odor, and Offgassing Requirements and Test Procedures for Materials in Environments that Support Combustion,” setting forth the basic requirements for oxygen service. However, this NHB left the details of implementing these requirements to the three manned flight centers: the Lyndon B. Johnson Space Center, George C. Marshall Space Flight Center, and John F. Kennedy Space Center. The implementation of these requirements at the Kennedy Space Center (KSC) was accomplished through KMI 8060.1, “KSC Materials Control Program for Selection of Materials Used in Environments that Support Combustion.” This document established the position of Center Materials Representative and created a Materials Application Advisory Board. The materials representative was given the final authority to approve materials and to serve as chairman of the advisory board. The advisory board functions as a committee to assess the usage of materials, to channel information to the materials representative, and to help evaluate requests for the usage of materials not on approved lists.
