What Is ASTM E2180 Antimicrobial Treated Surface Efficacy?
The ASTM E2180 is a standardized way of quantitatively evaluating the effectiveness of antimicrobial agents placed in flat hydrophobic materials, such as polymers. It is designed to ensure that microorganisms are indeed in contact with the treated hydrophobic surface.
Because it may be difficult to evenly distribute the microorganisms on the hydrophobic surface, the protocol accounts for this by mixing the microbial inoculum with an agar slurry. The agar slurry ensures that the microorganisms are in close contact with the antimicrobial-treated surface so that a precise assessment of the antimicrobial agent’s effectiveness can be made.
Applications and Benefits of ASTM E2180 Antimicrobial Treated Surface Efficacy Testing
Scope
ASTM E2180 applies to polymeric materials, hydrophobic surfaces, and flat solid materials that contain incorporated antimicrobial agents. The standard evaluates antimicrobial activity against bacteria such as Pseudomonas aeruginosa, Klebsiella pneumoniae, and Staphylococcus aureus, as well as yeast and fungal conidia. The method measures the reduction in viable microorganisms on the test surface after a defined contact period, providing an assessment of the material’s antimicrobial effectiveness.

Our ASTM E2180 Testing Procedure
Preparation & Inoculation
Microorganisms are mixed into a molten agar slurry, which is evenly spread onto treated and control samples.
1Primary Incubation
Samples are incubated for 24 hours (up to 96 hours for resistant organisms).
2Microbial Recovery & Plating
Surviving organisms are recovered into neutralizing broth, serially diluted, and plated on agar media.
3Incubation & Analysis
Plates are incubated, colonies counted, and log/percent reduction calculated.

Why Choose Infinita Lab for Antimicrobial Treated Surface Efficacy Testing
ASTM E2180 determines the quantitative antimicrobial effectiveness of agents incorporated into or bound to polymeric and hydrophobic surfaces. Results are based on the reduction in surviving microorganisms on treated surfaces compared with untreated controls after exposure.
The method is applicable to mainly flat, two-dimensional polymeric and hydrophobic materials, including plastics, epoxy resins, and other hard surfaces treated with antimicrobial agents.
ASTM E2180 primarily evaluates antibacterial activity, but the method can also be used with other microorganisms such as yeast and fungal conidia, when appropriate for the testing objective.
Treated and untreated control specimens are inoculated using an agar-slurry matrix that promotes uniform contact with the surface. After the specified exposure period, surviving microorganisms are recovered, counted, and compared to calculate the percent reduction attributable to the antimicrobial treatment.
Yes. ASTM E2180 allows antimicrobial-treated surfaces to be evaluated over time, including comparisons of washed and non-washed specimens, to assess persistent antimicrobial activity and long-term durability of the treatment.
