ASTM E 3227 : 2020

1.1This test practice determines the relative fungal growth inhibition properties of materials treated with an active biocidal agent. Samples of porous treated materials, such as textiles, 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 identical untreated materials is used to measure relative antifungal properties of the treated identical materials.

1.2This test practice must be performed by individuals experienced and adept in microbiological procedures and in facilities suitable for the handling of the species under test.

1.3This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4This 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.
