Sunlight, i.e. invisible short-wave ultraviolet (UV-C) rays have an antibacterial effect. UV-C rays are also extremely dangerous, because they damage the genetic DNA material of cells, but they are completely absorbed in the ozone layer of the atmosphere and do not penetrate to the Earth's surface.
IEC published IEC PAS 63313:2021, Position statement on germicidal UV-C irradiation - UV-C safety guidelines which contains guidelines for the manufacture, installation and use of UV-C sources and products. They are used in hospital rooms, operating rooms, hotels, production facilities, etc. to remove viruses and bacteria using artificial UV-C radiation of quartz lamps. UV lamps for home use are also available on the market. Due to the harmful effects on eyesight and skin, they must not be used in rooms where people, plants or animals are.
Draft Serbian standard naSRPS EN IEC 62471-6, Photobiological Safety of Ultraviolet Lamp Products, provides the optical radiation safety requirements for ultraviolet lamp products, including UV LED products. This standard provides requirements for:
- optical radiation safety assessment and ultraviolet-product risk groups;
- user information for safety measures;
- appropriate labelling of ultraviolet lamp products.
This draft is currently in the Public Enquiry stage until 7 September 2021, and all interested parties can submit comments and/or remarks on its text. ISS NTC N062, Electromedical equipment, will consider the received comments and remarks and forward them to the responsible IEC TC.
