Antibacterial testing is to detect the inhibitory effect of some materials on certain microorganisms, including bacteria testing and mold testing. Testing the antibacterial properties of daily chemical products, disinfection products, coatings films, metal materials, building materials, ceramics, leather, textiles/knitwear, polymer materials, packaging materials, nanomaterials, photocatalytic materials, insulating materials, etc. It is an important measure for protection and also a legal obligation required by the state for product operators. As a world-renowned professional, comprehensive, and international independent third-party testing agency, CIRS C&K Testing has launched antibacterial testing services to ensure relevant products and materials meet the requirements of relevant antibacterial standards. CIRS C&K Testing provides you with professional testing services and issues authoritative testing reports.
