If an antimicrobial agent that is shown to be removed from the surface by Section 13 satm utilized in this test methodology, controls must be included such that appropriate neutralization steps are including during recovery and enumeration. 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.

ASTM E – Method Determining the Antimicrobial Activity

The electronic file may not be reproduced in any way. The number of viable organisms from the suspension is determined and the percent reduction is calculated by comparing retrievals from appropriate controls. This dynamic shake flask test was developed for routine quality control and screening tests in order to overcome difficulties in using classical antimicrobial test methods to evaluate substrate-bound antimicrobials. 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.

Link to Active This link will always route to the current Active version of the standard. 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 a challenge suspension during the test period.

The antimicrobial activity of a substrate-bound, non-leaching antimicrobial agent is dependent upon direct contact of microbes with the active chemical agent. ASTM grants you a license as follows: 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.

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.

Surface antimicrobial activity is determined by comparing results from the test sample to controls run simultaneously. The right to access the electronic files of ASTM Standards is for purposes of viewing for individual use only. For example, water soluble antimicrobials will be prone to removal from the 110 surface using the method described in Section 13 but insoluble compounds will not.

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