This microbial inoculated agar slurry is then spreaded onto the test and untreated control material triplicate samples minimum. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
The method focuses primarily on assessing antibacterial activity; however, other microorganisms such as yeast and fungal conidia may be tested using this method. When bacterial inoculum is applied on the surface of plastics or other hydrophobic materials with incorporated preservatives, the surface tension of the polymer generally causes the microbial suspension of inoculum to separate from its surface, so that the microorganisms in the suspension may not contact the treated surface.
Calculation of percent reduction of bacteria from treated versus untreated samples is made.
Work Item s – proposed revisions of this standard. Proper microbial contact to an antimicrobial surface is necessary to evaluate the antimicrobial activity.

Copyright c nbsp; W. In addition, yeasts or fungal conidia can be used if the levuricidal or antifungal activity is to be evaluated. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Bacterial colonies from e2108 dilution series are counted and recorded.
To evaluate the antibacterial activity, the solution of molten agar is inoculated with 2e180 standardized culture of Staphylococcus awtmPseudomonas aeruginosa or Klebsiella pneumoniae. Exposure periods may be modified up to 96 h to address more resistant microorganisms. After the chosen contact time has elapsed, the microorganisms are eluted in a neutralizing solution and the percentage of recovery compared with the respective controls is calculated.
This test method facilitates the testing of hydrophobic surfaces by utilizing cells held in an agar slurry matrix.

Comparisons between the numbers of survivors on preservative-treated and control hydrophobic surfaces may also be made. Standard Test Method for determining the activity of incoporated antimicrobial agents in polymeric or hydrophobic materials.
ASTM E test procedure also permits determination of shelf-life or long term stability of an antimicrobial treatment which may be achieved through testing both non-washed and washed samples s2180 a time span. ASTM E test method can determine the presence of antimicrobial activity in plastics or hydrophobic surfaces.
Link to Active This link will always route to the current Active version of the standard. After the specified contact time 24 h commonly usedsurviving microorganisms are recovered via elution of the agar slurry inoculum from the test substrate into neutralizing broth.
To get the suspension of bacteria, or other microorganisms, to contact uniformly with the surface treated with antimicrobials, in this test the inoculum is placed in a mixture with agar, in order to decrease the surface tension forming a pseudomembrane that provides a more intimate contact with the evaluated surface.
Ecotoxicology – Test with algae, Daphnia magnaCrustaceans Palaemon spp. If you not change browser settings, you agree to it. These antimicrobial agents require contact with the microbial cell to e180 its maximum activity. This method also makes it possible to evaluate the useful life or the duration of the activity of the incorporated antimicrobial agent by testing washed or unwashed samples over a period of time.
Historical Version s – view previous versions of standard. ASTM E test method based on agar slurry inoculum facilitate good contact of microorganisms with antimicrobial treated hydrophobic surfaces.

An untreated control sample is also required. Eight to ten working days if commonly tested organisms are tested.
The percent reduction in the surviving populations of challenge bacterial cells at 24 h versus those recovered from a non-treated control is determined.
