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.

The susceptibility of the species to particular biocides could be altered depending on its life stage cycle. One-hour contact time in a buffer solution allows for metabolic stasis in the population. Link to Active This link will always route to the current Active version of the standard.

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. No other units of measurement are included in this standard.

This test method is designed to evaluate the antimicrobial activity of non-leaching, antimicrobial-treated specimens under dynamic contact conditions. For example, water soluble antimicrobials will be prone to removal from the test surface asm the method described in Section 13 but insoluble compounds will not.

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.

To determine if a compound is immobilized in all conditions or during the end use of the product additional testing may be required. 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. It is for this reason that the use of the term leaching throughout this document is limited to only the testing conditions described herein.

The number of viable organisms from the suspension is determined and the percent reduction is ast by comparing retrievals from appropriate controls. This dynamic shake flash test was developed for routine quality control and screening test. Surface antimicrobial activity is determined by comparing results from the test sample to controls run simultaneously.

The test determines the antimicrobial activity of a treated specimen by shaking samples of surface-bound materials in a concentrated bacterial suspension for a one hour contact time.

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.

Summary of Test Method: The right to access the electronic files of ASTM Standards is for purposes of viewing for individual use only. In addition the electronic files may not be downloaded or distributed elsewhere over asmt networks or otherwise. 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.

The antimicrobial activity of a substrate-bound, non-leaching antimicrobial agent is dependent upon direct contact of microbes with the active chemical agent. This test method standardizes both the growth conditions of the challenge species and substrate contact times to reduce the variability associated with growth phase of the microorganism.
