Measurement of Antibacterial Activity on
Plastics Surfaces (Plastics)
1. This International Standard (ISO) specifies quantitative test methods to determine the antibacterial activity of antibacterial finished textile products, including nonwovens.
2. It is appropriate for all textile products, such as cloth, wadding, thread and material for clothing, home furnishings and various goods independently of the type of antimicrobial agent used (organic or inorganic, natural or artificial) or the method of application (built-in, after-treatment or grafting).
3. It depends on the projected application and on the environment where the textile product is intended to be used.
4. Customers can choose an appropriate method for determination of antimicrobial activity: Absorption method: evaluation method, bacterial suspension is inoculated directly onto samples , The Colony Plate Count method and the Adenosine Triphosphate Luminescence method are also specified for quantifying the bacterial enumeration.
The JIS Z 2801/ISO 22196 test is designed to quantitatively measure 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 can detect low-level antimicrobial effects exerted over long periods of time.
The JIS Z 2801/ISO 22196 test takes 3 to 4 days.
At Microbe Investigations, we understand the need for accuracy and speed. We test for the JIS Z 2801/ISO 22196 using the following viruses: Pseudomonas aeruginosa, Escherichia coli (ATCC 8739), Staphylococcus aureus (ATCC 6538P), Enterococcus hirae, Klebsiella pneumoniae (ATCC 4352), MRSA, Salmonella entercia, Candida Albicans. Additional strains can be added on request.
