REALM Project: Test Plan for Materials


To inform the research for the REALM Project, Battelle has prepared the document, Test Plan for the Natural Attenuation of SARS-CoV-2 as a Decontamination Approach. This Test Plan describes how the Battelle laboratory will test for the longevity of the COVID-19 virus on materials and how long it takes for the virus to naturally attenuate—essentially, how long the material needs to be left alone before the virus is undetectable. Key points about the testing:

  • COVID-19 virus will be applied to materials and then checked after one (1) hour of drying time (called T0). The samples will then be evaluated for the presence of virus after four selected timepoints which can change with each test.
  • The environmental conditions are being maintained at approximately 72 degrees Fahrenheit and relative humidity of 40%.
