The ISO 11930 - Preservative Challenge Test is a procedure for evaluating the antimicrobial protection of a product. Much like the USP <51>, it evaluates the activity of preservatives or other intrinsic characteristics of a product that help maintain the safety of a product by inhibiting the growth and...
The Assessment of Antibacterial Finished Products The International Standard (ISO) 20743 method, titled "Textiles - Determination of Antibacterial Activity of Antibacterial Finished Products", is designed to test the ability of fabrics that have been treated with antimicrobial agents to prevent microbial growth and to kill microorganisms, over an 18-24 hour...
Measurement of Antibacterial Activity on Plastics Surfaces and Other Non-Porous Surfaces The ISO 22196 method is designed to quantitatively test the ability of plastics to inhibit the growth of microorganisms (Bacteriostatic) or kill them (Bactericidal), over a 24 hour period of contact. It is a relatively sensitive assay, meaning that it...
The ISO 27447 method, titled "Test Method for Antibacterial Activity of Semiconducting Photocatalytic Materials", determines the ability of photocatalytic materials to inhibit the growth of microorganisms or kill them. Both hard surfaces (non-porous) and textiles could contain a photocatalyst or have photocatalytic films and can be tested using this method by measuring the number...
