ASHRAE Standard 185.2-2020
ASHRAE Standard 185.2-2020 Method of Testing Ultraviolet Lamps for Use in HVAC&R Units or Air Ducts to Inactivate Microorganisms on Irradiated Surfaces Test standards form the foundation for air-cleaner selection in the ventilation industry. U.S. Environmental Protection Agency (USEPA) literature stated that the most important need in the area of ultraviolet germicidal irradiation (UVGI) was industry standards to rate installed devices. Standards for testing and reporting on products under controlled conditions are essen-tial to users and specifiers so that they can compare products, predict levels of performance under specified operating conditions with reasonable certainty, and determine appropriate UVGI efficiencies for specific situations.

Historically, standards for testing air cleaners were developed in response to the needs of the day. Protection of machinery and coils came first, then reduction of soiling. Concerns about indoor air quality (IAQ) and respirable particles, protection of products during manu-facture, and protection of HVAC equipment prompted development of test standards based on particle size. Interest in controlling airborne infectious contaminants or viable species that produce chemical contaminants as metabolic byproducts created the need for a test standard for UVGI equipment.
In 2007 efforts were divided between the production of two standards: ANSI/ASHRAE Standard 185.1, Method of Testing UVC Lights for Use in Air Handling Units or Air Ducts to Inactivate Airborne Microorganism, and ANSI/ASHRAE Standard 185.2, Method of Testing Ultraviolet Lamps for Use in HVAC&R Units or Air Ducts to Inactivate Microorganisms on Irradiated Surfaces.
