Disinfectants  EN 1276 Test for bactericidal activity of chemical disinfectants

Chemical disinfectants entering the European market should undergo a quantitative microbiological assessment according to the European standard EN1276 to determine the bactericidal efficacy of chemical disinfectants and antiseptics. Bactericidal or antibacterial products such as disinfectants and antiseptics are used in industrial, domestic and institutional sectors. These products are developed to inhibit and combat a wide range of microorganisms in a range of products including food, cosmetics, healthcare, medical devices, home and personal care. Evaluation of its bactericidal activity via EN1276 is important to ensure product quality and efficacy.

With the global outbreak of the new coronavirus, the demand for various chemical disinfectants has increased significantly. The bactericidal effect of various disinfectants must be confirmed through experimental evaluation before they can have the desired effect of the product in controlling the epidemic. A valid EN1276 test report can also gain customers' trust in products and accelerate the market circulation of products.

The EN1276 antibacterial test can prove the product's disinfecting effect on various bacteria and viruses by testing the killing effect of several bacteria commonly used in laboratories.
