Presence of residual antimicrobial activity indicates the presence aatm a leaching type of antimicrobial agent. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

ASTM E – Method Determining the Antimicrobial Activity

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. Summary of Test Method: The electronic file may not be reproduced in any way. The susceptibility of the species to particular biocides could be altered depending on its life stage cycle. Astn test method is designed to evaluate the antimicrobial activity of non-leaching, antimicrobial-treated specimens under dynamic contact conditions.

In addition the electronic files may not be downloaded or distributed elsewhere over computer networks or otherwise. 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. Historical Version s – view previous versions of standard. 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.

This standard does not purport to address all of the safety concerns, if any, associated with its use. Work Item s – proposed revisions of this standard. Remember me for one month. 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. The number of viable organisms from the suspension is determined and the percent reduction is calculated by comparing retrievals from appropriate controls.

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.

For example, water soluble antimicrobials will be prone to removal from e2194 test surface using the method described in Section 13 but insoluble compounds will not. No other units of measurement are included in this standard.

It is the responsibility of the user of this standard to e1249 appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. The antimicrobial activity of a substrate-bound, non-leaching antimicrobial agent is dependent upon direct contact of microbes with the active chemical agent.

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.
