Exposure periods may be modified up to 96 h to address more resistant microorganisms. 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 adtm forming a pseudomembrane that provides a more intimate contact with the evaluated surface.

ASTM E test method can determine the presence of antimicrobial activity in plastics or hydrophobic surfaces.

Bacterial colonies from each dilution series are counted and recorded. Do not use Google Chrome Contact.

On hydrophobic surfaces, it is hard to spread the microorganisms. The usual contact time is 24 hours, but can be modified according to the manufacturer’s requirements up to 96 hours to deal with more resistant microorganisms.

Asttm addition, yeasts or fungal conidia can be astk 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. Therefore, it is great help in evaluating antimicrobial activity of hydrophobic antimicrobial treated surfaces.

ASTM E2180 – Antimicrobial Test

Comparisons between the numbers of survivors on preservative-treated and control hydrophobic surfaces may also be made. This microbial inoculated agar slurry is then spreaded onto the test and untreated control material triplicate samples minimum.

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.

This test method facilitates the testing of hydrophobic surfaces by utilizing cells held in an agar slurry matrix. No other units of measurement are included in this standard. ASTM E test method allows determination of quantitative differences in antimicrobial activity between untreated plastics or polymers and those with bound or incorporated low water-soluble antimicrobial agents.

Historical Version s – view previous versions of standard. 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. ASTM E test also help in determining the Comparisons between the numbers of survivors on preservative treated and control hydrophobic surfaces.

Proper microbial contact to an antimicrobial surface is necessary to evaluate the antimicrobial activity.

Other microorganisms such as yeast asm fungi may also be tested using this procedure. Ecotoxicology – Test with algae, Daphnia magnaCrustaceans Palaemon spp. 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.

Link to Active This link will always route to the current Active version of the standard. 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 over a time span.

Staphylococcus aureus ,Pseudomonas aeruginosa or Klebsiella pneumoniae. Work Item s – proposed revisions of this standard. Serial dilutions are made, plated and incubated for 48 h at a specified temperature dependent upon the optimal temperature for test organism.

Standard Test Method for determining the activity of incoporated antimicrobial agents in polymeric or hydrophobic materials. Polymeric materials such as vinyl fabrics, shower curtains and various medical devices are usually treated with antimicrobial agents. These antimicrobial agents require contact with the microbial cell to exert its maximum activity. To evaluate the antibacterial activity, the solution of molten agar is inoculated with a standardized culture of Staphylococcus aureusPseudomonas aeruginosa or Klebsiella pneumoniae.

It is the responsibility of the user of this standard to establish appropriate safety, aastm, and environmental practices and determine the applicability of regulatory limitations prior to use.
