Exciting News!
ZAPARAY is proud to announce the achievement of the BS 8628:2022 certification.
To address the lack of standardized testing for UV-C devices, the European disinfectant standard writing body released a new standard in Spring 2022: BS 8628:2022. This standard is tailored for UV-C disinfection devices, based on the existing EN 17272:2020 airborne surface disinfection standard with minor adjustments. It focuses on assessing the efficacy of UV-C devices in disinfecting surfaces within enclosed spaces.
In the Efficacy Test of BS 8628:2022, stainless steel carriers are inoculated with microorganisms and placed inside a test chamber. The UV-C manufacturer defines the specific carrier test location (this is the ‘weakest spot’, the area with least radiation in the device) and defines minimal UV-C dose to be registered by the UV-C sensors. After recording the requested UV-C radiation dose, carriers are processed, and the results are expressed in logarithmic scale for compliance assessment.
Key Features of BS 8628:
✅ Standardized method
✅ Quantitative assessment
✅ Wide microorganism coverage
✅ Direct radiation focus
✅ Process time determination
✅ Regulatory Compliance
By obtaining this certification, we reaffirm our commitment to quality and performance in UV disinfection solutions. Join us in creating safer, healthier environments with our unique UV-C-LED disinfection for heat sensitive objects!
Requirements of the BS 8628 standard:
Bactericidal activity: 5lg or greater reduction for vegetative bacteria and 4lg or greater reduction for bacterial spores and fungi on test-carriers compared to control-carriers not exposed to the process for the specified test organisms.
