JIS L 1902 and ISO 20743 Antimicrobial Methods
topic
ISO 20743 encompasses absorption, transfer, and printing inoculation methods that place defined bacterial suspensions onto fabric specimens, incubate under defined conditions, and enumerate survivors using ATP bioluminescence or plate counting; the standard covers both static and dynamic contact modes to accommodate different fabric architectures and antimicrobial mechanisms.
Role
The dominant international antibacterial textile standard harmonising Japanese JIS L 1902 and European test approaches, providing a reproducible framework for evaluating both bacteriostatic and bactericidal claims across diverse antimicrobial textile treatments in global markets.
