A detailed test design for the evaluation of procedures for the hygienic disinfection of hands is described together with suitable methods for statistical analysis of the results. In principle the release of testbacteria from the finger-tips of artificially contaminated hands is measured before and after disinfection. A procedure under test is accepted if it is not less effective than a standard-disinfection procedure. As such the disinfection with iso-propanol 60% (ml/ml) applied through 1 min was agreed upon. This standard procedure is to be performed the same day with the same day with the same testpersons and under identical environmental conditions prior to the procedure under test.
