本文件描述了实验室评估紫外线杀菌剂性能的方法 将安装在供暖、通风和空调管道中的辐射（UVGI）装置 （暖通空调）系统。 该方法包括对试验台、微生物、程序和数据的详细要求 计算和结果报告，以确定紫外线剂量模型微生物的UVGI设备在 几个气流速度。根据测试结果，管道内UVGI装置的空气消毒能力可以 应进行可靠的评估和比较。 如果已知给定微生物的敏感性常数，则该微生物的失活率 通过测试，可以进一步计算UVGI设备。交叉引用:ISO 15858 ISO 29464:2017ANSI/ASHRAE 185.1购买本文件时提供的所有现行修订版均包含在购买本文件中。

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 microorganism by the tested UVGI devices can be further calculated.Cross References:ISO 15858ISO 29464:2017ANSI/ASHRAE 185.1All current amendments available at time of purchase are included with the purchase of this document.
