• Abstract:
  As a result of the coronavirus disease 2019 (COVID-19) public health emergency, aircraft owners and operators may find it necessary to increase the frequency with which they disinfect aircraft interiors. The disinfectant procedures included conventional chemical liquid disinfectants and Ultraviolet-C (UV-C) germicidal irradiation. In the first two phases of this project, we evaluated the effects of liquid chemical disinfectants on materials used in aircraft seats and other interior applications. In the third phase of this project, long-term exposure to UV-C irradiation on various aircraft cabin interior materials has been investigated. In this study, eight different materials typically used in aircraft interiors, including seats, were considered. Three UV-C irradiation configurations with peak emissions at 222 nm, 253.4 nm, and 280 nm were selected. The test materials were subjected to accelerated UV-C aging tests at multiple cumulative dosage configurations, representing a single daily exposure over a time period of one, four, and eight years. Post the UV-C exposure, the materials were evaluated for change in weight, color, flammability performance, and mechanical properties.
