    Abstract

    The results of an investigation into the reproducibility of promoted combustion test data for various metallic materials are presented. Tests were conducted in the promoted combustion test fixtures at NASA's Marshall Space Flight Center, in gaseous oxygen at pressures from 0.7 MPa to 68.9 MPa. The tests were conducted using circular and square crosssection samples. The effects of sample size on pressure threshold reproducibility are discussed also.
