ASTM WK73519

    New Test Method for Quantitative Method for Determining the Efficacy of Antimicrobial Towelettes

    (What is a Work Item?)

    Developed by Subcommittee: E35.15 | Committee E35 | Contact Staff Manager


    1. Scope

    Instructions for performing a quantitative antimicrobial efficacy assessment of a pre-saturated towelette when challenged against Staphylococcus aureus and Pseudomonas aeruginosa. Antimicrobial towelettes, designed to decontaminate hard, non-porous surfaces, are diverse in size, matrix composition, and packaging; they also vary in label claims and use directions. This method provides log reduction as the quantitative measure of efficacy for antimicrobial towelettes against a test organism on a hard, non-porous surface. Product efficacy is considered a combination of the mechanical removal of inoculum from a surface and the chemical inactivation of the test microbe; this method does not differentiate between these two attributes.


    Towelette; antimicrobial; Staphylococcus aureus; Pseudomonas aeruginosa; wiping contaminated surfaces


    To generate a more stringent quantitative antimicrobial towelette efficacy test. The test is anticipated to be used to assess the efficacy of pre-saturated antimicrobial towelettes. The method will be used by federal labs, contract efficacy testing labs, and antimicrobial towelette manufacturers.

    The title and scope are in draft form and are under development within this ASTM Committee.
