    New Practice for Standard Test Practice for Qualitative Assessment of Antifungal Activity on Textiles

    (What is a Work Item?)

    WK66142

    1. Scope

    1. Scope 1.1 To determine the relative fungal growth inhibition properties of materials treated with an active biocidal agent. Samples of porous treated materials, such as textiles, paper, or carpet, are inoculated with a defined suspension of fungal conidia or spores and then incubated. The inhibition of growth or visible growth present on treated compared with untreated materials is used to measure relative antifungal properties of the treated materials. 1.2 This Standard must be performed by individuals experienced and adept in microbiological procedures and in facilities suitable for the handling of the species under test. 1.3 This standard may involve hazardous materials, operations, and equipment and 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. 1.4 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.

    Rationale

    This practice is needed to routinely measure the antifungal properties of textiles treated with antimicrobial agents to prevent the growth of odor causing fungi and visual fungal growth on a surface. Current methods unduly limit the types of antimicrobial agents that can be measured due to the method design. This current practice attempts to recreate conditions of fungal exposure that both reflect expected end-use of a textile but also promote potential growth on comparative untreated controls.

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