Quantitative Antibacterial Testing AATCC 100
topic
AATCC 100 inoculates fabric specimens with defined concentrations of Staphylococcus aureus and Klebsiella pneumoniae in nutrient broth, incubates for 24 hours, then enumerates surviving bacteria by dilution plating to calculate percentage bacterial reduction relative to untreated control specimens.
Role
The primary quantitative antibacterial test for treated textiles in North America, providing percentage reduction data used in antimicrobial performance claims for healthcare apparel, hygiene textiles, and consumer active-wear products incorporating silver, copper, triclosan, or quaternary ammonium treatments.
