Oxygen Partial Pressure and Oxygen Concentration Flammability: Can They Be Correlated?

Source

NASA possesses a large quantity of flammability data performed in International Space Station (ISS) airlock (30 % Oxygen 526 mmHg) and ISS cabin (24.1 % Oxygen 760 mmHg) conditions. As new programs develop, other oxygen and pressure conditions emerge. In an effort to apply existing data, the question arises: Do equivalent oxygen partial pressures perform similarly with respect to flammability? This paper evaluates how material flammability performance is impacted from both the maximum oxygen concentration (MOC) and maximum total pressures (MTP) perspectives. From these studies, oxygen partial pressures can be compared for both the MOC and MTP methods to determine the role of partial pressure in material flammability. This evaluation also assesses the influence of other variables on flammability performance. The findings presented in this paper suggest flammability is more dependent on oxygen concentration than equivalent partial pressure.
