1.1.This standard is designed for use with a mechanized device (the Wiperator; Appendix 1) to test pre-wetted towelettes. 1.2.Two species of vegetative bacteria, one Gram-positive coccus and one Gram-negative bacillus, representing important nosocomial pathogens, are used to separately contaminate disks of magnetized and brushed stainless steel in order to test the towelettes for their relative ability to: 1.2.1 Decontaminate non-porous environmental surfaces experimentally-contaminated with vegetative bacteria; and 1.2.2 Transfer any acquired bacterial contamination on the towelettes to clean surfaces. 1.3This test method is not meant for use with towelettes for decontamination of skin. 1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses, if any, are for information only. 1.5 This test method should be performed by persons with training in microbiology in facilities designed and equipped for work with infectious agents at the appropriate biosafety level.
There is increasing popularity of disinfectant-soaked wipes for decontamination of non-porous environmental surfaces in healthcare and other settings. However, any testing of such wipes does not properly reflect their field use. The proposed standard would be of interest to manufacturers, end-users, government regulators as well as researchers.
