Disinfectant Efficacy Testing to BS EN Standards

We offer a wide range of tests for determining the efficacy of disinfectant products, such as wipes, sprays, hand sanitisers, automated units. In addition to offering UKAS accredited reports, we offer a consultancy service to guide you on the process of getting your new disinfectant/decontamination system approved.

“Quantitative suspension test for the evaluation of bactericidal activity of chemical disinfectants and antiseptics used in food, industrial, domestic and institutional areas”

Test items are inoculated with a bacterial suspension for a specified time. After the contact time, the suspension is neutralised and plated out. Upon incubation, the plates are inspected for growth of bacteria and compared with the validation and control plates, to determine possible log reductions.

Results for this test are expressed in logarithm reduction for each microorganism tested.

“Quantitative suspension test for the evaluation of bactericidal activity in the medical area”

Test items are inoculated with a bacterial suspension for a specified time. After the contact time, the suspension is neutralised and plated out. Upon incubation, the plates are inspected for growth of bacteria and compared with the validation and control plates, to determine possible log reductions.

Results for this test are expressed in logarithm reduction for each microorganism tested.

“Quantitative suspension test for the evaluation of fungicidal or yeasticidal activity of chemical disinfectants and antiseptics used in food, industrial, domestic and institutional areas”

Test items are inoculated with a fungal suspension for a specified time. After the contact time, the suspension is neutralised and plated out. Upon incubation, the plates are inspected for growth of fungal colonies and compared with the validation and control plates, to determine possible log reductions.

Results for this test are expressed in logarithm reduction for each microorganism tested.

“Quantitative suspension test for the evaluation of fungicidal or yeasticidal activity in the medical area”

The test item is added to a test suspension containing the test organism and the interfering substance for a specified time. After the contact time, the suspension is neutralised and plated out. Upon incubation, the plates are inspected for growth of fungal colonies and compared with the validation and control plates, to determine possible log reductions.

Results for this test are expressed in logarithm reduction for each microorganism tested.

“Chemical disinfectants and antiseptics – Quantitative test method for the evaluation of bactericidal and yeasticidal activity on non-porous surfaces with mechanical action employing wipes in the medical area (4-field test)”

As part of this test, the test surface is marked with 4 squares of 5×5 “test fields”. Test field 1 is inoculated with the test suspension consisting of bacteria or yeast in a solution of interfering substances. After the inoculum is dried, a wipe is soaked with a sample of the test product, and that wipe is then used to wipe the test surface across the 4 marked test fields. After the specified contact time, a moistened cotton swab is used to recover the test organisms from the test fields. The number of surviving microorganisms from each test field is then calculated.

Results for this test are expressed in logarithm reduction for each microorganism tested and each product concentration separately.

“Chemical disinfectants and antiseptics – Methods of airborne room disinfection by automated process – Determination of bactericidal, mycobactericidal, sporicidal, fungicidal, yeasticidal, virucidal and phagocidal activities”

Test carriers are inoculated with the test organism suspension containing the interfering substance. After air drying the inoculum, the test carriers are exposed to the airborne disinfection process to be evaluated. Upon completion of the decontamination process, carriers are retrieved, and the surviving test organisms are recovered into the recovery liquid. Samples are then plated, incubated, and the number of colonies is counted.
