It is for this reason that the use of the term leaching throughout this document is limited to only the testing e214 described herein. Work Item s – proposed revisions of this standard. Surface antimicrobial activity is determined by comparing results from the test sample to controls run simultaneously.

The susceptibility of the species to particular biocides could be altered depending on its life stage cycle. This dynamic shake flash test was developed for routine quality control and screening test.

Summary of Test Method: Presence of residual antimicrobial activity indicates the presence of a leaching type of antimicrobial agent.

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. Record and report presence of solution activity. Link to Active This link will always route to the current Active version of the standard. This test method is designed to evaluate the antimicrobial activity of non-leaching, antimicrobial-treated specimens under dynamic contact conditions.

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.

To determine if a compound is immobilized in all conditions or during the end use of the product additional testing may be required. This test method is only intended to determine efficacy as described in 4. Maria Curry ext Wrist Action Shaker. 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.

ASTM E2149 Antimicrobial Activity

The presence of a leaching antimicrobial is determined post-test. 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. One-hour contact time in a buffer solution allows for metabolic stasis in — population.

For example, water soluble antimicrobials will be prone to removal from the test surface using the method described in Section 13 but insoluble compounds will not. This standard does not purport to address all of the safety concerns, if any, associated with its use.

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.
