NEW METHODS OF MICROBIAL AND SURFACE CONTAMINATION REMOVAL

摘要

This paper describes a laboratory method that was developed to evaluate microbial removal efficiencies of wall and floor cleaning techniques used in cleanrooms. Two floor and two wall materials were tested in a Dynamic Microbial Test Chamber using the method. The reductions in Staphy-iococcus epidermidis counts after cleaning were calculated and a statistical analysis performed to compare the techniques.
