What Is Antimicrobial Testing?

Antimicrobial testing is the laboratory evaluation of a material, chemical, coating, surface, or product to determine its ability to inhibit or reduce microorganisms.

Antimicrobial activity may be evaluated against bacteria, fungi, yeast, and other microorganisms, depending on the product, intended application, and selected testing method.

Antimicrobial testing is commonly used by manufacturers to evaluate product performance, compare formulations, support research and development, and generate technical data.

Common applications include:

• Antimicrobial coatings and surface treatments

• Antibacterial plastics and polymers

• Antimicrobial textiles and fabrics

• Treated building materials

• Medical-related materials and components

• Antimicrobial packaging materials

• Industrial coatings and protective surfaces

• Consumer products with antimicrobial treatments

• Antimicrobial additives and formulations

• Specialty materials designed to inhibit microbial growth

EMSL Analytical provides microbiological testing expertise to support the evaluation of antimicrobial products and materials.

What Is Antibacterial Testing?

Antibacterial testing measures the ability of a material, treatment, or product to inhibit bacterial growth or reduce viable bacterial populations under specified laboratory conditions.

Testing may compare a treated sample with an untreated control to determine whether the antibacterial treatment produces a measurable reduction in bacterial populations.

Depending on the testing method, results may be expressed as:

• Percent bacterial reduction

• Log reduction in bacterial concentration

• Antibacterial activity values

• Inhibition zones

• Changes in viable bacterial counts

• Comparative performance between treated and untreated materials

Antibacterial testing is valuable for manufacturers developing products intended to resist bacterial growth or provide antibacterial functionality.

Antimicrobial and Antibacterial Testing Methods

EMSL Analytical can assist clients in identifying testing approaches appropriate for their materials and intended applications. Commonly used industry standards include the following. Confirm individual method availability, scope, and accreditation with EMSL before submitting samples.

ISO 22196 – Antibacterial Activity on Plastics and Non-Porous Surfaces

ISO 22196 is a widely recognized international testing method for measuring antibacterial activity on plastics and other non-porous surfaces.

This method is commonly used for evaluating antibacterial treatments incorporated into or applied onto solid materials.

Typical applications include antibacterial plastics, treated polymer surfaces, non-porous coatings, and manufactured components.

ASTM E2149 – Antimicrobial Activity Under Dynamic Contact Conditions

ASTM E2149 evaluates antimicrobial activity of antimicrobial agents immobilized on or incorporated into materials under dynamic contact conditions.

The method is often considered for treated surfaces, fibers, polymers, and materials designed to exhibit antimicrobial properties.

ASTM E2180 – Antimicrobial Activity of Polymeric or Hydrophobic Materials

ASTM E2180 evaluates antimicrobial activity in or on polymeric and hydrophobic materials.

This method may be appropriate for certain plastics, coatings, and materials where other antibacterial test approaches are less suitable.

AATCC 100 – Antibacterial Finishes on Textile Materials

AATCC TM100 is commonly used to evaluate antibacterial performance of treated textile materials.

Typical applications include treated fabrics, upholstery, industrial textiles, uniforms, and specialty textile products.

ASTM E2315 – Time-Kill Evaluation of Antimicrobial Activity

ASTM E2315 provides a framework for assessing antimicrobial activity using a time-kill procedure.

This approach can help evaluate microbial reductions after specified contact periods under controlled laboratory conditions.

ASTM E1054 – Evaluation of Antimicrobial Neutralization

ASTM E1054 is used to evaluate whether antimicrobial agents can be effectively neutralized during microbiological testing.

Proper neutralization helps ensure antimicrobial efficacy results accurately reflect microbial survival at the specified contact time.
