This dynamic shake flash test was developed for routine quality control and screening test. Link to Active This link will always route to the current Active version of the standard.
To determine if a compound is immobilized in all conditions or during the end use of the product additional testing may be required. Antimicrobial Hard Surfaces For Bacteria.
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. Interpretation of antimicrobial efficacy is product dependent and final decision lies with the client.

Test Package Request Form. The result is represented as log reduction or percentage reduction.
Following exposure, a sample of the test organism suspension is removed quantitatively assayed for survivors. Satm concentrations in the treated and untreated samples are usually determined at 0, 1 or 24 hours contact time.
The presence of a leaching antimicrobial is determined post-test. No regulated reduction limits currently exist for general antimicrobial claims made using this method. Maria Curry ext Wrist Action Shaker.
Accuratus Lab Services
Rapid testing and quick reliable results are of utmost importance today. The antimicrobial activity of a substrate-bound, non-leaching antimicrobial agent is dependent upon direct contact of microbes with the active chemical 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. Bioassays pH Simulation studies. Work Item s – proposed revisions of this standard.
In this method, treated test samples are placed in a laboratory flask containing a dilute suspension of test organism, commonly Escherichia coli. 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.

Presence of residual antimicrobial activity indicates the presence of a leaching type of antimicrobial agent.

Organisms typically used in this method: It is for this reason that the use of the term leaching throughout this document is limited to only the testing conditions described herein. The ASTM E test method is designed to evaluate the antimicrobial activity of non-leaching non-water soluble antimicrobials surfaces made of plastic, rubber, silicone and treated fabric material.
ASTM E – Microbe Investigations (MIS)
No other units of measurement are included in this standard. This test method is designed to evaluate the antimicrobial activity of non-leaching, antimicrobial-treated specimens under dynamic contact conditions. A sample requirement for 1 test piece varies from 0. These difficulties include ensuring contact of inoculum aetm treated surface as in AATCCflexibility of retrieval at different contact times, use of inappropriately applied static conditions as in AATCCsensitivity, and reproducibility.
The test quantitatively evaluates ashm effectiveness of a sample treated with a non-leaching antimicrobial agent by shaking in an organism suspension.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Summary of Test Method: 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.
2e149 of Test In this method, treated test samples are placed in a laboratory flask containing a dilute suspension of test organism, commonly Escherichia coli. 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.
ASTM E2149 Antimicrobial Activity
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. ASTM E is one of the only ways to test an irregularly shaped antimicrobial object, r2149 as a thread, powder, 3D molded plastic. This website stores cookies on your computer.

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.
This test ensures good contact between bacteria and the treated fibre by constant agitation of the test specimen in a bacterial suspension during the test period 1hour.
This test method is designed to evaluate the resistance of specimens treated with a non-leaching antimicrobial agent to the growth of microbes under dynamic zstm conditions. Antimicrobial Textiles For Fungi.
