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. To determine if a compound asgm immobilized in all conditions or during the end use of the product additional testing may be required.

Record and report presence of solution activity.

It is for this reason that the use of the term leaching throughout aastm document is limited to only the testing conditions described herein. You currently cannot view this content. 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 number of viable organisms from the suspension is determined and the percent reduction is calculated by comparing retrievals from appropriate controls. 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.

This standard does not purport to address all of the safety concerns, if any, associated with its use. No further reproductions authorized. ASTM grants you a license as follows: The antimicrobial activity of a substrate-bound, non-leaching antimicrobial agent is dependent upon direct contact of microbes with the active chemical agent.

Summary of Test Method: 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.

Work Item s – proposed revisions of this standard. The presence of a leaching antimicrobial is determined post-test. 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.
