ASTM E2149 Antimicrobial Activity

The presence of a leaching antimicrobial is determined post-test. This dynamic shake flash test was developed for routine quality control and screening test.

Historical Version e249 – view previous versions of standard. No other units of measurement are included in this standard. This test method standardizes both the growth asfm of the challenge species and substrate contact times to reduce the variability associated with growth phase of the microorganism.

ASTM E – Method Determining the Antimicrobial 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. 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.
