Methods and solutions offered
Access established methodologies including ASTM E2149, ASTM E2180, AATCC 100, and JIS Z 2801/ISO 22196. Our consultative approach helps you select the right testing protocol for your specific claims and regulatory requirements, with the capability to develop custom solutions when needed.
ASTM E2149: Tests antimicrobial activity by shaking treated samples in a microbial suspension (typically E. coli) and measuring log reduction after exposure.
ASTM E2180: Evaluates antimicrobial properties of polymeric or hydrophobic materials by inoculating a treated surface with a microbial slurry and assessing log reduction after 24 hours against organisms such as S. aureus, P. aeruginosa, and K. pneumoniae.
AATCC 100: Assesses antibacterial finishes on textiles by exposing treated samples to microbes (S. aureus, K. pneumoniae), incubating, and measuring log reduction.
Mildew Fungistatic Test: Determines effectiveness of antimicrobial treatments on fabrics or hard surfaces by evaluating mold growth (Aspergillus niger) under high humidity conditions for products considered effective mildew fungicides.
JIS Z 2801/ISO 22196: Measures antimicrobial activity of surface treatments using international standards, with results expressed in percent and log reduction.

Frequently asked questions
What types of claims can be validated through treated article testing?
We support validation for general antimicrobial claims, antibacterial properties, and mildew resistance through established test methods like ASTM E2149, ASTM E2180, and AATCC 100. For many of these methods, no regulated reduction limits exist, with performance criteria typically determined by the sponsor. We can help you understand appropriate parameters for your specific applications.
How do you ensure testing meets regulatory requirements?
Our technical experts stay current with testing methodologies and industry standards. We provide comprehensive documentation of test results including log reduction and percent reduction measurements, delivering the data needed to support your treated article claims and registration.
