The number of viable organisms from the suspension is determined and the percent reduction is calculated by comparing retrievals from appropriate controls. It is for this reason that the use of the term leaching throughout this document is limited to only the testing conditions described herein.

This dynamic shake flash test was developed for routine quality control and screening test. The susceptibility of the species to particular biocides could be altered depending on its life stage cycle. No items in cart. This test method is only intended to determine efficacy as described in 4.

This dynamic shake flask test was developed for routine quality control and screening tests in order to overcome difficulties in using classical antimicrobial test methods to evaluate substrate-bound antimicrobials. These difficulties include ensuring contact of inoculum to treated surface as in AATCCflexibility of retrieval at different contact times, use of inappropriately applied static conditions as in AATCCsensitivity, and reproducibility.

Surface antimicrobial activity is determined by comparing results from the test sample to controls run simultaneously. No other units of measurement are included in this standard.

ASTM E – Method Determining the Antimicrobial Activity

This test method ensures good contact between the bacteria and the treated fiber, fabric, or other substrate, by constant agitation of the test specimen in a challenge suspension during the test period.

If an antimicrobial agent that is shown to be removed from the surface by Section 13 is utilized in this test methodology, controls must be included such that appropriate neutralization steps are including during recovery and enumeration.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The test determines the antimicrobial activity of a aatm specimen by shaking samples of surface-bound materials in a concentrated bacterial suspension for a one hour contact time.

The antimicrobial activity of a substrate-bound, non-leaching antimicrobial agent is dependent upon direct contact of microbes with the active chemical agent.
