Standards Development
This document specifies safety requirements of excimer sources for germicidal purposes.
UV-C sources and luminaires as an effective method for germicidation, attracts more and more attention, especially after COVID-19 epidemic, they are widely used in public infrastructures to achieve sterilization.
This document acknowledges the emerging of 222 nm excimer sources for germicidal purpose and the need for the safety specification.
The provisions in this document represent the technical knowledge of experts from the field of the UV
radiation for germicidal purpose, and are developed in close context with the safety of other type of UV
radiation sources for germicidal purpose, e.g., low pressure mercury sources for germicidal purpose. Based on 34/WG 23 discussion, it is agreed that from safety aspect, limiting excimer source in this document only for 222 nm product is unnecessary. “excimer source” is then used instead of the specific w avelength range limitation
