ASTM E2149 Standard Test Method for Determining the Antimicrobial Activity of Immobilized Antimicrobial Agents Under Dynamic Contact Conditions

The ASTM E2149 test is designed to evaluate the resistance of non-leaching antimicrobial-treated samples to the growth of microbes under dynamic contact conditions. This dynamic shake bottle test was developed for routine quality control and screening testing to overcome the difficulties of using conventional antimicrobial testing methods to evaluate substrate-bound antimicrobials.

ASTM E2149 Standard Test Method for Determining the Antimicrobial Activity of Immobilized Antimicrobial Agents Under Dynamic Contact Conditions

These challenges include maintaining contact of the inoculum with the treated surface (as in AATCC 100), flexibility of retrieval at different contact times, use of inappropriately applied static conditions (as in AATCC 147), precision and repeatability. This test also includes hard water, proteins, blood, serum, various chemicals,

Surface antimicrobial activity is determined by comparing results from the test sample with controls run simultaneously. The presence of a leaching antimicrobial is determined both before and after by the presence of a zone of inhibition.

This test method should only be performed by persons trained in microbiological techniques.
