The DOE consisted of ; ; five independent tests per material per test run. Survival data with 0 survival was below the limit of detection of 1.0 log10. APC—aircraft performance coating; solution control—wet virus inoculum—not dried on a material; NA—not tested for DOE. Hours (h). Polypropylene material from the TPP® tubes was the material.
