This test method is designed to evaluate the antimicrobial activity of non-leaching, antimicrobial-treated specimens under dynamic contact conditions. 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 Adtmsensitivity, and reproducibility.

It is for this reason that the use of the term leaching throughout this document is limited to only the testing conditions described herein.

ASTM E – Method Determining the Antimicrobial Activity

This dynamic shake flash test was developed for routine quality control and screening test. One-hour contact time in a buffer solution allows for metabolic stasis in the population. 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. 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. 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.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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 presence of a leaching antimicrobial is determined post-test. 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.

The antimicrobial activity of a substrate-bound, non-leaching antimicrobial agent is dependent upon direct contact of microbes with the active chemical agent. Work Item s – proposed revisions of this standard. Surface antimicrobial activity is determined by comparing results from the test sample to controls run simultaneously.
