Terminology: Antibacterial Activity Value
Antibacterial Activity Value
The Japanese Industrial Standard (JIS) issued a testing method to determine the antibacterial activity (expressed as an Index), of antimicrobial-treated (compounded) materials or articles.
The antibacterial activity is calculated dividing the number of bacteria present after 24 hours of cultivation onto a testing treated article/product (C) into the number of bacteria present after 24 hours of cultivation onto the corresponding untreated (without antimicrobial agent) article/product (B).
An antibacterial index of >2.0 (≥99% killing ratio) of a treated article with antimicrobial agent might be considered as “Antibacterial Article”
