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.

Presence of residual antimicrobial activity indicates the presence of a leaching type of antimicrobial agent. Link to Active This link will always route to the current Active version of the standard.

Work Item s – proposed revisions of this standard. This test method is only intended to determine efficacy as described in 4. Register for a trial account.

For example, water soluble antimicrobials will be prone to removal from the test surface using the method described in R2149 13 but insoluble compounds will not. The antimicrobial activity of a substrate-bound, non-leaching antimicrobial agent is dependent upon direct contact of microbes with the active chemical agent. Surface antimicrobial activity is determined by comparing results from the test sample to controls run -.

This standard does not purport to address all of the safety concerns, if any, associated with its use. This test method is designed to evaluate the antimicrobial activity of non-leaching, antimicrobial-treated specimens under dynamic contact conditions.

The presence of a leaching antimicrobial is determined post-test. 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.

Summary of Test Method: 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. You currently cannot view this content.

ASTM E – Method Determining the Antimicrobial Activity

This test method ensures good contact between the bacteria and the treated fiber, fabric, or other substrate, by constant agitation of the test specimen in xstm challenge suspension during the test period. This dynamic shake flash test was developed for routine quality control and screening test.

This dynamic shake flask test was developed for routine quality control and screening tests asmt order to overcome difficulties in using classical antimicrobial test methods to evaluate substrate-bound antimicrobials. Maria Curry ext Wrist Action Shaker. The susceptibility of the species to particular biocides could be altered depending on its life stage cycle.

Work Item s – proposed revisions of this standard. It is for this reason that the use of the term leaching throughout this document is limited to only the testing conditions described herein. Enter your personal account email address to request 110 password reset: Note 1 — Stresses may include laundry, wear and abrasion, radiation and steam sterilization, UV exposure, solvent manipulation, temperature susceptibility, or similar physical or chemical manipulation.

One-hour contact time in a buffer solution allows for metabolic stasis in the population.

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