Organisms typically used in this 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. 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.

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 dynamic shake flash test was developed for routine quality control and screening test. No other units of measurement are included in this standard.

Antimicrobial Textiles For Fungi. It is for this reason that the use of the term leaching throughout this document is limited to only the testing conditions described herein. No regulated reduction limits currently exist for general antimicrobial asstm made using this method. Record and report presence of solution activity. Test Package Request Form.

ASTM E – Microbe Investigations (MIS)

The ASTM E test method is designed to evaluate the antimicrobial activity of non-leaching non-water soluble antimicrobials surfaces made of plastic, rubber, silicone and treated fabric material. In this test method, appropriately standardized concentration of freshly cultured microorganism is prepared. Referenced Documents purchase separately The documents listed below are referenced within the subject standard e21149 are not provided as part of the standard.

Shubhda Research Institute Complete solutions for all your Microbiology e214 needs! Interpretation of antimicrobial efficacy is product dependent and final decision lies with the client. Materials evaluated by this method may be comprised of fabric, paper, powder or other solid materials. To determine if a compound is immobilized in all conditions or during the end use of the product additional testing may be required. All the samples are shaken in dynamic shake flasks in asm wrist action shaker to ensure good contact between the bacteria and the treated fibre, fabric, or other substrate by constant agitation of the test specimen in a bacterial suspension during the test period.
