UVC Material Degradation Test

Textiles, plastics, paints, and many other products are damaged by germicidal sterilizing UV-C radiation becoming more popular to fight corona virus threat

  • Overview +

    Disinfection and decontamination of surfaces by exposure to UVC radiation (specifically, 253.7 nm) has been used for more than 40 years against a whole suite of human pathogens. The use of adequate doses of UV-C has been shown to achieve a high level of inactivation of a near-relative of COVID-19’s virus, SARS COV-1. The International Ultraviolet Association (IUVA) believes similar results can be expected when treating current COVID-19’s virus, SARS COV-2.

    Given the global impact and severity of COVID-19, there has been an enormous spike in the interest of using UVC as a disinfectant. Numerous devices are now on the market that use UVC. Hospitals, automobiles, airplanes, trains, commercial and residential interior space are all possible use-cases for periodic decontamination. Further examples are interior of school buses, airplanes, taxi cabs and other ride-sharing vehicles, public waiting areas, museums, production and office sites and many more.

    Note: The terms “UVC” and “UV-C” are both used in the literature interchangeably. UVC radiation (or UVC light) is defined as electromagnetic radiation between 100-280 nm. Alternative names for UVC include short-wave UV and ultraviolet germicidal irradiation, or UVGI.

  • Market Needs +

    With the promulgation of UVC as a disinfectant, materials engineers from all industries, as well as electronic devices, testing laboratories, etc. are increasingly concerned that UV-C disinfection adds a new severe photodegradation stress to their materials, for which negative effects on materials have not been investigated. They fear that their materials – textiles, plastics, coatings, etc. – may severely suffer from this “new stress”, which is much harsher than solar UV, and may have considerably reduced service lifetime.

    Material durability testing equipment against UVC stress is not widely available on the market. Many companies have recently contacted Atlas for support to simulate the output of these UVC disinfectant devices to evaluate long-term exposure effects.

    Examples for affected products, materials, and applications are:

    • Consumer electronics
    • Electric and electronic devices
    • Automotive interior
    • Interior of trains, plans, railway station and airport facilities
    • Rental cars, public and school buses
    • Interior Materials and furniture, e.g. textiles, carpets/flooring, laminates, etc.
    • Hospitals, educational, administrative, and other public facilities
    • Research institutes
    • and many more …

    The Atlas UVCTest™ is designed to test the durability of materials exposed to UVC radiation centered at 254 nm. It is based on the popular UVTest™ fluorescent/UV platform, with special modifications for safety and reliability. The output of the UVC-254 lamps simulates the UV-C germicidal radiation used by sterilization devices.
