Disinfection effects of different domestic laundering procedures were investigated under conditions stated in IEC 62958 Ed.1 (59D/423/DPAS-2014, Dec2014). Textile bioindicators were applied for evaluation of the disinfection efficiency using two cultures of microorganisms: Enterococcus faecium ATCC 6057 and Staphylococcus aureus ATCC 6538. Different classical laundering procedures (Normal/Time/Eco) for washing domestic textiles were performed, consisting of main-washing, rinsing, and spinning. An SensoCare Gorenje d.d. (SLO) drum washing machine was used, with a programmable washing process, and a microprocessor regulation of time, temperature, and mechanical action. Used laundering detergent IEC-A was composed from: 77 % of basic powder, 20 % of SPT (oxidizer), 3 % of TAED (bleach activator). The amounts of detergent was determined according to SIST EN 60456. Microorganisms’ colonies on the textile biondicators (CFU, Colony Forming Units) before and after the disinfection laundering procedure were counted, and a calculation of the reduction efficiency (RED) was performed as determined by SIST standards. It was found that the reduction of more than 5 log steps was achieved when Cotton-Normal/Time/Eco laundering procedures at 40 0C were performed.
