UV-C resistance testing at the VDE Institute

UV-C rays are found in the range of 100 and 280 nanometers. In this range they can kill germs. This special property allows the reproduction of microorganisms such as bacteria, viruses and protozoa to be prevented, and also kills such organisms. This method of killing germs by means of UV-C is mainly employed in the areas of air sterilization, water sterilization, surface sterilization and food hygiene.

UV-C radiation sources are increasingly found in electrical devices. Due to their energy-rich properties, UV-C rays have an impact on most modern materials and products, as they are capable of changing their mechanical and electrical properties. The consequence of this is that cracks or fractures occur in the component, which in turn compromises safety. The suitability of the materials used with regard to UV-C radiation resistance should thus inevitably be provided for in product development.

The VDE Institute offers standards-based tests for the testing of non-metallic materials for their UV-C resistance. International standards already require testing of the UV-C resistance of non-metallic materials. Precursor here is the IEC 60335-1:2010/AMD2:2016 “Household and similar electrical appliances - Safety”. In light of this development, the VDE Testing and Certification Institute has addressed test methods and their feasibility ahead of time. Thus the UV-C resistance test can already be carried out today.
