BS EN 1040:2005 Chemical disinfectants and antiseptics. Quantitative suspension test for the evaluation of basic bactericidal activity of chemical disinfectants and antiseptics. Test method and requirements (phase 1)

EN 1040 is a suspension test to determine whether a chemical disinfectant or antiseptic does or does not have a basic bactericidal activity.

Unlike Phase 2 testing, Phase 1 testing cannot be used for claim support for biocidal activity, as the testing does not include the use of interfering substance within the test and is therefore not as close to real life use of a product compared to Phase 2 testing. It can be used as an initial assessment for bactericidal efficacy of products and may also be used to ensure that active substances chosen within product formulations are responsible for the biocidal activity of a product. It can also be used to assess co-formulants to ensure that they are not providing biocidal activity, particularly for those in combinations that may not be listed within UK or EU regulations for biocidal use.

The test parameters are simplified for this test, including the microorganisms used, the test temperatures and the contact times used for testing.
