Description of ASTM-E2471 2023

ASTM E2471-23

Redline Standard: Standard Test Method for Using Seeded-Agar for the Screening Assessment of Antimicrobial Activity In Carpets




ASTM E2471

Scope

1.1 This test method is designed to evaluate (qualitatively) the presence of antimicrobial activity in or on carpets. Use this test method to qualitatively evaluate both antibacterial and antifungal activity.

1.2 Use half strength (nutrient and agar) tryptic soy agar as the inoculum vehicle for bacteria and half strength potato dextrose agar as the inoculum vehicle for mold conidia. Use of half strength agars may reduce undue neutralization of an antimicrobial due to excessive organic load.

1.3 This test method simultaneously evaluates (both visual and stereo-microscopic) antimicrobial activity both at the fiber layer and at the primary backing layer of carpet.

1.4 Use this test method to assess the durability of the antimicrobial treatments on new carpets, and on those repeatedly shampooed or exposed to in-use conditions.

1.5 Knowledge of microbiological techniques is required for the practice of this test method.

1.6 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.

1.7 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.
