DANSK DSF/ISO/FDIS 15714 PDF

This standard describes a method in laboratory to assess the performance of ultraviolet germicidal irradiation (UVGI) devices which will be mounted in-duct in heating, ventilating and air-conditioning (HVAC) systems. The method includes the detailed requirements for test rig, microorganisms, procedures, data calculation and result report to determine the UV dose to model microorganisms by an UVGI device at several air flow rates. By knowing the results, the capacity of in-duct UVGI devices for air disinfection could be evaluated and compared reliably. If the susceptibility constant of a given microorganism is known, the inactivation rate of that microorganism while using the relative UVGI devices could be further calculated
