Abstract
After extensive materials and component level tests, a series of full-scale-spacecraft-mockup flammability tests provided the final verification that the Apollo command module and lunar module were safe. The flight atmosphere at reduced oxygen pressure and two possible spacecraft launch atmospheres were evaluated. The safer of the two launch atmospheres was defined. Interior mockups of Apollo command and lunar modules were used in a series of 173 flammability tests. They were conducted in oxygen at reduced pressures of 5.8 psia and 6.2 psia and in two possible launch atmospheres, 16.2 psia 100 percent oxygen and 16.2 psia 60 percent oxygen/40 percent nitrogen. Fires were started in the mockups at locations selected as representative of potential ignition hazards.
