The process also enables the assessment of an antimicrobial treatment’s “shelf-life” or long-term durability. This may be done by evaluating both non-washed and washed samples over a period of time. This is a quantitative test method to check the antimicrobial activity of hydrophobic surfaces. This test standard utilizes an agar slurry inoculum vehicle which facilitates even contact between microorganisms and antimicrobial-treated hydrophobic surfaces
The required incubation period, often 24 hours, is given to the treated and untreated rudders to sit at the proper temperature. To determine the initial concentration of the inoculated slurry, separate controls are immediately neutralised, sonicated, serially diluted, and plated. The infected agar slurry is then adequately removed from the slides using sonication for a certain amount of time, followed by the counting of the surviving organisms. Dilutions are made, then the necessary agar is plated, followed by incubation.
Get Certified ASTM E2180 for Proven Antimicrobial Performance
ASTM E2180 certification will show that internationally accepted antimicrobial testing practice is adhered to. Laboratory testing has been used to verify that added antimicrobial agents contain quantifiable microbial inhibitory properties as well as satisfy regulatory and customer standards. Certification helps in claims of antimicrobial products, increases credibility in the market, and provides uniformity in quality control and verification of products.
