Work Item s – proposed revisions of this standard. One-hour contact time in a buffer solution allows for metabolic stasis in the population. Aztm Item s – proposed revisions of this standard. 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. To determine if a compound is immobilized in all conditions or during the end use of the product additional testing may be required.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Presence of residual antimicrobial activity indicates the presence wstm a leaching type of antimicrobial agent.
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.

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.
No further reproductions authorized. This test method is f2149 to evaluate the antimicrobial activity of non-leaching, antimicrobial-treated specimens under dynamic contact conditions. Surface antimicrobial activity is determined by comparing results from the test sample to controls run simultaneously. Summary of Test Method: No items in cart.

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. 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.

ASTM E – Method Determining the Antimicrobial Activity
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.
This test method is only intended to determine efficacy as described in 4. Remember me for one month. Print 1 2 3 4 5 page sstarting from page current page.
ASTM E2149 Antimicrobial Activity
No other units of measurement are included in this standard. The susceptibility of the species to particular biocides could be altered depending on its life stage cycle. In addition the electronic files may not be downloaded or distributed elsewhere over e2194 networks or otherwise.
This test e149 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. Maria Curry ext Wrist Action Shaker.
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. It is for this reason that the use of the term leaching throughout this document is limited to only the testing conditions described herein.
