Recent FDA enforcement policy supports the use of Tenney environmental chambers for bioburden reduction on N95 respirators during the coronavirus (COVID-19) public health emergency. The use of dry heat processing to reduce the risk of transmission of the SARS-CoV-2 virus, and limited reuse of NIOSH-approved filtering face-piece respirators, were cited in the FDA guidance.

A manufacturer in the chemical products industry will use an environmental walk-in chamber to perform temperature and humidity testing of heat pump and air handling systems containing hydrofluorocarbon refrigerants.

An automotive company will use a walk-in chamber to thermally test the insulation used in interiors. The insulation will be subjected to different thermal conditions to test the R factor integrity.
