ISO 15714:2019

Method of evaluating the UV dose to airborne microorganisms transiting in-duct ultraviolet germicidal irradiation devices

PUBLISH DATE 2019
ISO 15714:2019

This document 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 a UVGI device at several airflow rates. By the testing results, the capacity of in-duct UVGI devices for air disinfection can be evaluated and compared reliably.

If the susceptibility constant of a given microorganism is known, the inactivation rate of that micro-organism by the tested UVGI devices can be further calculated.
