The antimicrobial activity of a substrate-bound, non-leaching antimicrobial agent is dependent upon direct contact of microbes with the active chemical agent. Please sign into an account with a subscription to this content, or email for asttm at support madcad.

ASTM E – Method Determining the Antimicrobial Activity

Historical Version xstm – — previous versions of standard. 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. 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 presence of a leaching antimicrobial is determined post-test. Note 1 — Stresses may include laundry, wear and abrasion, radiation and steam sterilization, UV exposure, solvent manipulation, temperature susceptibility, or similar physical or chemical manipulation.

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.

In addition the electronic asgm may not be downloaded or distributed elsewhere over computer networks or otherwise.

The number of viable organisms from the suspension is determined and the percent reduction is calculated by comparing retrievals from appropriate controls. It is f2149 this reason that the use of the term leaching throughout this document is limited to only the testing conditions described herein. These difficulties include ensuring e21449 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.

No items in cart. 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 aatm and enumeration.

This standard does not purport to address all of the safety concerns, if any, associated with its use. This standard does not purport to address all of the safety concerns, if any, associated with its use. Presence of residual antimicrobial activity indicates the presence of a leaching type of antimicrobial agent. Surface antimicrobial activity is determined by comparing results from the test sample to controls run simultaneously.

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.
