Uncontained UVC Testing for Healthcare Facilities and Laboratories

Testing and certification of smart appliances and open air robots that emit uncontained ultraviolet radiation for unattended facility disinfection

There are three type of ultraviolet (UV) light: UVA, UVB and UVC. While UVC germicidal lamps are designed to kill bacteria and inactivating viruses, this technology poses a health and safety risk to patients and users if directly exposed, and the effects on medical equipment must be carefully considered.

Besides UVC equipment designed to individually disinfect medical tools and devices in enclosed or “contained” chambers, many healthcare providers are also now taking advantage of uncontained UVC technology to disinfect unattended rooms. These rooms may very well house complex electrical medical devices and laboratory equipment with relatively little previous surface or performance testing post exposure to UVC light. This inherently presents additional safety risk as end-use environments are sanitized by both new chemical compounds and UVC technology with limited harmonized protocol.

Uncontained UVC lighting solutions often involve companion predictive modeling to inform decisions about where to disinfect. Light rays may emanate from either smart/activated UVC appliance or robots. These robotic-enabled devices may be either stationary or roaming and are intended to clean and sanitize multiple room surfaces (fixtures, flooring and specialty healthcare products).

UL can help manufacturers of uncontained UVC devices address critical healthcare challenges by testing and certifying them according to relevant safety standards. We can evaluate both finished healthcare equipment and components (ballasts, LED drivers, UVC sources, controls, sensors) to be used in device assembly.



UL can perform photobiological assessments resulting in a comprehensive test report. This process typically takes 4-5 weeks via our specialty UV equipment used by our experienced biomedical engineers. We can also issue a UL Mark and certificate of compliance/conformance for UL/IEC 61010-1, the Standard for Medical Electrical Equipment, Part 1: General Requirements for Safety and related safety testing.

In addition to helping manufacturers demonstrate conformity to safety standards, UL can also provide third-party verification of performance claims such as ability for a device to disinfect a surface via our UL Marketing Claim Verification service. Please note that UL safety certifications do not verify efficacy claims.
