ASTM E 2149

Antimicrobial Activity of Immobilized Agents under Dynamic Contact Conditions

Test Purpose
The purpose of this microbiology lab test is to examine the rate-of-kill of a treated test material against a Sponsor selected pure culture microorganism suspension. This is accomplished by exposing the target microorganism to the test material and inspecting the solution for potential survivors at various time periods.

Test Summary
A suspension of test organism is added to a flask containing the test material and shaken. The test organism is exposed to the test material for each specified contact time. After exposure, an aliquot of the suspension is transferred to a neutralizer and assayed quantitatively for survivors. Appropriate purity, sterility, microorganism population and neutralization controls are performed.
