BS EN 13727 is an international standard that focuses on quantitative suspension tests for the evaluation of the bactericidal activity in the medical area. BS EN 13727 specifies a test method and the minimum requirements for bactericidal activity of chemical disinfectant and antiseptic products that form a homogeneous, physically stable preparation when diluted with hard water, or - in the case of ready-to-use products - with water. Products can only be tested at a concentration of 80% or less (97% with a modified method for special cases) as some dilution is always produced by adding the test organisms and interfering substances.
Note: BS EN 13727 is intended to determine the activity of commercial formulations or active substances under the conditions in which they are used. BS EN 13727 corresponds to a phase 2 step 1 test.BS EN 13727 cannot be used to evaluate the activity of products against Legionella in water systems against mycobacteria and bacterial spores.
BS EN 13727 on quantitative suspension tests for the evaluation of the bactericidal activity is useful for:
All weights of chemical substances given in BS EN 13727 refer to the anhydrous salts. Hydrated forms may be used as an alternative, but the weights required shall be adjusted to allow for consequent molecular weight differences.
BS EN 13727 specifies a suspension test for establishing whether a chemical disinfectant or an antiseptic has a bactericidal activity in the area and fields described in the scope.
BS EN 13727 takes into account practical conditions of application of the product including contact time, temperature, test organisms and interfering substances, i.e. conditions which may influence its action in practical situations. Each utilization concentration of the chemical disinfectant or antiseptic found by this test corresponds to the chosen experimental conditions.
