Evaluation of airliner cabin textile materials after vapour phase hydrogen peroxide decontamination

“…Thus, a VHP cycle with a 150 ppm enclosure concentration was conducted for wool specimens (this a tensile strength and elongation to failure; b maximum tear stress and average tear stress 14 Effect of 10 VHP cycles at 450 ppm followed by aging in laboratory air for up to 100 days. Raw data are provided in Table 9 concentration is close to that used for field trials of the use of VHP on aircraft 13,14 and is around the minimum concentration that can be regarded as being well into the sporicidal range which begins at ,80 ppm. It may be possible to use very dilute VHP purely as an antiviral, but the concentration range needed remains under investigation as of the date of writing.…”

“…The exposure environment was designed to be more destructive than that used for field trials, which employed an ,450 ppm inlet concentration and a 150-200 ppm enclosure concentration. 13,14 Detailed parameters of the VHP cycle can be found in a previous study related to the effect of decontamination on airliner metallic materials. 1 There were slight differences in the ramp rate up to the working concentration and aeration time for the small and large enclosure because of the performance limit of the VHP 1000ED apparatus.…”
