Quantitative suspension test for the evaluation of bactericidal activity of disinfectants or antiseptics
Disinfectants and antiseptics are primarily used to kill harmful microorganisms or inhibit their growth. However, not all the detergents hold the same efficacy against microorganisms, especially resistant bacterial strains.
EN 1276 test is a quantitative suspension test to evaluate the efficacy of chemical disinfectant and antiseptic formulations against a broad range of bacteria. This test method is only applicable for disinfectant formulations used in food, industrial, domestic and institutional areas. Exceptions with this test method are that it is not applicable for areas where disinfectant is medically indicated, on living tissues, and viral strains.
Bactericidal activity of chemical disinfectants shall not be confused with virucidal activity. For accessing both the activities, different test methods are available. As already explained above, EN 1276 is used to check bactericidal activity, whereas EN 14476 test is performed to determine the virucidal activity of chemical disinfectants and antiseptics.
At Microbe Investigations, we recognize the importance of accuracy and precision for our customers. With our constant efforts, we envision the provision of quality and reliable microbiology testing services at an affordable cost.
EN 1276 is a quantitative suspension test for the evaluation of bactericidal activity of disinfectants or antiseptics.
EN 1276 test is applicable for chemical disinfectant and antiseptic products such as handrubs and handwashes that have different applications in industrial, institutional areas, etc.
The EN 1276 test method typically needs 4-5 days to complete.
EN 1276 can be tested against different strains of bacteria. Such as Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, Enterococcus hirae, Escherichia coli K12, Enterococcus faecium, Salmonella typhimuriun, Lactobacillus brevis, Enterobacter cloacae. Additional strains can be added on request.
