本文件描述了一种实验室评估紫外线杀菌辐射（UVGI）装置性能的方法，该装置将安装在暖通空调（HVAC）系统的管道中。 该方法包括试验台、微生物、程序、数据计算和结果报告的详细要求，以确定UVGI装置在几种气流速率下模拟微生物的紫外线剂量。通过测试结果，可以可靠地评估和比较管道内UVGI装置的空气消毒能力。 如果已知给定微生物的敏感性常数，则可以进一步计算该微生物被测试的UVGI装置的失活率。

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 an 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.
