Détails

1.1 This guide provides information on various test methods currently available to assess antifungal activity on natural or synthetic substrates.

1.2 Knowledge of microbiological techniques is required for the practice of this guide.

1.3 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, health, and environmental 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.


Significance and Use:

4.1 Fungi are known to produce objectionable odors, stains, and premature biodeterioration of various consumer products and construction substrates including textiles, carpet, ceiling tile, gypsum wallboard, lumber, and plasticized vinyl and other polymers.

4.2 Antifungal activity is typically:

4.2.1 Determination of article susceptibility to fungal colonization,

4.2.2 Determination of fungistatic activity (qualitative determination of prevented or delayed fungal colonization), and

4.2.3 Determination of fungicidal/sporicidal activity (quantitative determination of spore kill).

4.3 The degree of required surface examination varies from gross visual examination to detailed microscopic assessment among these methods.

4.4 This guide provides an overview of established methods and suggestions for their applicability, with consideration to the type of substrate treated or the type of antifungal treatment being assessed.
