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. Work Item s – proposed revisions of this 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. This standard does not purport to address all of the safety concerns, if any, associated with its use. The test quantitatively evaluates the atm of a sample treated with a non-leaching antimicrobial agent by shaking in an organism suspension.
Record and report presence of solution activity.
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 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 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. Immobilized antimicrobial agents, such as surface bonded materials, are not free to diffuse into their environment under normal conditions of ee2149.
This dynamic shake flash test was developed for routine quality control and screening test.
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.

ASTM E – Microbe Investigations (MIS)
This test method ensures good contact between the bacteria and the treated fiber, fabric, or other substrate, by constant agitation of the test specimen aatm a challenge suspension during the test period. The presence of a leaching antimicrobial is determined post-test.
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.
Microbial concentrations in the treated and untreated samples are usually determined at 0, 1 or 24 hours contact time.
It has been developed for routine quality control and screening tests and is used to evaluate substrate bound antimicrobials. 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 contact conditions. One-hour contact time in a buffer solution allows for metabolic stasis in the population.
