It is for this reason that the use of the term leaching throughout this document is limited to only the testing conditions described herein. The number of viable organisms from the suspension is determined and the percent reduction is calculated by comparing retrievals from appropriate controls.
The antimicrobial activity of aetm substrate-bound, non-leaching antimicrobial agent is dependent upon direct contact of microbes with the active chemical agent.

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.
This dynamic shake flash test was developed for routine quality control and screening test. In addition the electronic files may not be downloaded or distributed elsewhere over computer networks or otherwise.
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.

This test method ensures good contact between the bacteria and the treated fiber, fabric, e1249 other substrate, by constant agitation of the test specimen in a challenge suspension during the test period. 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.
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 test method is only intended to determine efficacy as described in 4. Link to Active This link will always route to the current Active version of the standard.
One-hour contact time in a buffer e219 allows for metabolic stasis in the population. Work Item s – proposed revisions of this standard. Are you sure you want to empty the cart? Facebook Linkedin Instagram Twitter Google.
This standard does not purport to address all of the safety concerns, if any, associated with its use. This standard does not purport to address all of the safety concerns, if any, — with its use. Surface antimicrobial activity is determined by comparing results from the test sample to controls run simultaneously.
