    1. Scope

    1.1 This test method is designed for use with a mechanized device (the Wiperator, Appendix X1) 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 contaminate separately disks of magnetized and brushed stainless steel to test the towelettes for their relative ability to: 1.2.1 Decontaminate nonporous environmental surfaces experimentally contaminated with vegetative bacteria and 1.2.2 Transfer any acquired bacterial contamination on the towelettes to clean surfaces. 1.3 This 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. 1.6 It is the responsibility of the investigator to determine whether good laboratory practice (GLP) regulations are required and to follow them where appropriate. 1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

    There is increasing popularity of disinfectant-soaked wipes for decontamination of nonporous 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.
