Abstract : This handbook is a compilation of chemical and physical property test data obtained during qualification and receiving inspection testing of nonmetallic materials for the Viking Mars Lander (NAS1-9000) program at the Denver Division of Martin Marietta Corporation. The compilation presented here is unique in that all tests have been carried out by one group of test personnel. This familiarity with all test procedures and materials minimizes the possibility of unintentional modifications of test techniques and misinterpretation of data and their presentation. The information presented has, as a minimum, thermochemical data showing degradation as a function of temperature from room temperature through 773 deg K (500 deg C). These data include activation energies for thermal degradation, rate constants, and exo- and/or endotherms. Thermal degradations carried out under vacuum include mass spectral data taken simultaneously during the decomposition. Many materials have supporting data such as condensation rates of degassed products and isothermal weight loss. Changes in mechanical, electrical and thermal properties after exposure to 408 deg K (l35 deg C) in nitrogen for times ranging from 380 to 570 hours are included for many materials. Over 400 organic/polymeric materials were considered for use throughout the Viking Mars lander capsule program. jg p16
