BS EN 13727:2012+A2:2015 Evaluation of Bactericidal activity of Chemical Disinfectants used in the Medical area (phase 2, step 1)
EN 13727 is a quantitative suspension test that determines the bactericidal activity of chemical disinfectants used in the medical area. The common areas where disinfection is medically indicated include patient care settings, nursing homes, dental facilities, clinics of schools, etc.
EN 13727 test ensures that the given disinfectant formulation should be effective against a range of pathogenic bacteria to meet its bactericidal efficacy claims under practical applications.
This test is applicable to a myriad of commercial products that are used in medical care facilities for disinfection –
- Hygienic handrub,
- hygienic handwash,
- surgical handrub,
- surgical handwash,
- instrument disinfectants
- and surface disinfectants.

EN 13727 Test Method
- Test sample is exposed to bacterial suspension in the presence of an interfering substance.
- Mixture is maintained at specific contact period time and under other mandatory conditions
- After the end of contact period, 1 ml of mixture is neutralized.
- Neutralizing extract is incubated for 2 days and viable colonies are enumerated.
- Reduction in viable colonies is compared with original culture size.
MIS has introduced a comprehensive range of microbiology efficacy testing for chemical disinfectants and antiseptics claiming bactericidal properties. In addition to EN 13727, we are also capable of doing disinfectant efficacy testing using EN 13697.
In antiviral efficacy testing of chemical disinfectants and antiseptics, EN 14476 is a very frequently performed test method in our laboratory.
