Standard Practice for Determining the Fungus-Eliminating Effectiveness of Hygienic Handwash and Handrub Agents Using the Fingerpads of Adults
SIGNIFICANCE AND USE
5.1 This in vivo procedure is designed to test the ability of hygienic handwash or handrub agents to eliminate fungal contamination from experimentally-contaminated hands. Since the two thumbpads and all eight fingerpads can be used in any given test, it allows for the incorporation of an input control (two), control for culturable cells of the test fungus remaining after the inoculum has dried (two), fungal cells eliminated after treatment with a control or reference solution (two), and up to four replicates to assess the fungus-eliminating efficiency of the formulation under test. No more than 100 µL of the test fungal suspension is required to complete one test.
5.2 Whereas this practice is designed to work with fungi, similar ASTM standards exist for testing against viruses (Test Method E1838) and vegetative bacteria (Test Method E2276).
5.3 The levels of culturable microorganisms left on hands after washing can be reduced further by drying the washed hands with paper, cloth, or warm air (5). A step for the drying of fingerpads after exposure to the control or test solution, therefore, has not been included to avoid fungal removal by the drying process itself.
5.4 This practice is not designed to test surgical hand scrubs or preoperative skin preps.
5.5 The level of contamination with culturable fungi on each fingerpad after the drying of the inoculum should be at least 104 CFU so that it would permit the detection of up to a 4-log10 reduction in the viability titer of the test organism by a test formulation under the conditions of this test. This in itself does not represent the product performance criterion, which may vary depending on the jurisdiction and the nature of the formulation being evaluated.
SCOPE
1.1 This practice is designed to assess the ability of hygienic handwash and handrub agents to reduce levels of fungal contamination on hands (3) . This practice is not meant for use with surgical hand scrubs (Test Method E1115) or preoperative skin preps (Test Method E1173).
1.2 Performance of this procedure requires the knowledge of regulations pertaining to human experimentation.3
1.3 The practice should be performed by persons with training in microbiology in facilities designed and equipped for work with infectious agents at biosafety level 2 (4).
1.4 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.5 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.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Human hands are frequently in contact with other surfaces and can readily acquire transient

microbial contamination. Fungi are common among these types of contaminants (1, 2), particularly
in healthcare settings and where food is handled. Standardized methods to assess the fungus-
eliminating potential of handwash and handrub agents have not been available and this practice
addresses the gap.
