Fig. 1

PVC material with polyurethane surface coating measuring 20 × 50 cm is prepared by recording four 5 × 5 cm squares. Test field 1 is contaminated with a defined amount of virus inoculum (virus suspension + interfering substance). This is followed by a wiping process (2-s motion) with a wipe, which was fixed under a unitary weight. After a defined exposure time of the test substance, the remaining test viruses are recovered from all four test fields with swabs. The aim is to show a reduction of the test viruses on test field 1 and the carryover to the previously virus-free test fields 2–4 (schematic drawing according to European Standard EN 16615:2015)
