Quantitative suspension test for the evaluation of bactericidal activity of disinfectants or antiseptics
1. The test method involves a sample of product added to a test suspension of bacteria in a solution of an interfering substance (Clean Condition: 0.3g/l and Dirty condition: 3g/l of Bovine Serum Albumin).
2. The mixture is maintained at the chosen test temperature for the adopted contact time.
3. At the end of this contact time, an aliquot is taken and neutralized immediately.
4. Following a 5-minute neutralization period, 1 ml is plated onto Tryptone Soya Agar to detect surviving test bacteria.
EN 1276 is used to evaluate the bactericidal activity of disinfectants or antiseptics that have different application in industrial, institutional, etc areas.
To run the EN 1276 test method, usually takes 4-5 days.
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.
