Establishment of a standardized Phase 2/Step 2 method for virucidal surface disinfection: Results of an interlaboratory ring trial (4-field test)


June 10, 2026

A publication with this title has been published in "The Journal of Hospital Infection", with Dr. Florian H. H. Brill as one of the contributing authors. The publication concludes that the virucidal 4-field test demonstrates promising applicability as a Phase 2/Step 2 method and represents a valuable candidate for incorporation into future European standards. The method is particularly relevant for assessing ready-to-use wipes, as virucidal efficacy depends on the combined effects of wipe material, released liquid, and mechanical action, which may substantially differ from results obtained in the absence of mechanical application. Representative-of-use validation methods are therefore essential for assessing disinfectant efficacy in hospitals, long-term care facilities, and public spaces.
