1.1 本试验方法定义了评估紫外线杀菌照射（UVGI）灯装置（汞蒸汽灯泡、发光二极管或氙弧灯）的试验条件，这些装置旨在杀死/灭活沉积在无生命载体上的流感病毒。 1.2 本试验方法定义了与紫外线（UV）光谱和评估UVGI剂量相关的术语和方法。 1.3 该测试方法定义了可降低UVGI表面杀灭效果（即，弄脏）的测试注意事项。 1.4 提供了调整UVGI剂量以影响活流感病毒水平降低的方案( 附件A1 ). 1.5 本测试方法不解决阴影问题。 1.6 该测试方法只能由受过微生物学培训的人员使用，并应符合微生物和生物医学实验室生物安全提供的指导。 2. 1.7 该测试方法针对流感病毒 1.8 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.9 警告- 许多监管机构已将汞指定为一种危险物质，可导致严重的医疗问题。汞或其蒸汽已被证明对健康有害，并对材料具有腐蚀性。处理汞和含汞产品时要小心。有关更多信息，请参阅适用的产品安全数据表（SDS）。当地或国家法律禁止销售汞或含汞产品，或两者兼有。用户必须确定其所在地销售的合法性。 1.10 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.11 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 本试验方法确定了UVGI装置用于减少沉积在载体上的活菌的有效性。 5.2 本试验方法评估了沾污剂对UVGI抗菌效果的影响。 5.3 本试验方法确定了UVGI的传输剂量。

1.1 This test method defines test conditions to evaluate ultraviolet germicidal irradiation (UVGI) light devices (mercury vapor bulbs, light-emitting diodes, or xenon arc lamps) that are designed to kill/inactivate influenza virus deposited on inanimate carriers. 1.2 This test method defines the terminology and methodology associated with the ultraviolet (UV) spectrum and evaluating UVGI dose. 1.3 This test method defines the testing considerations that can reduce UVGI surface kill effectiveness (that is, soiling). 1.4 Protocols for adjusting the UVGI dose to impact the reductions in levels of viable influenza virus are provided ( Annex A1 ). 1.5 This test method does not address shadowing. 1.6 The test method should only be used by those trained in microbiology and in accordance with the guidance provided by Biosafety in Microbiological and Biomedical Laboratories. 2 1.7 This test method is specific to influenza viruses 1.8 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.9 Warning— Mercury has been designated by many regulatory agencies as a hazardous substance that can cause serious medical issues. Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials. Use caution when handling mercury and mercury-containing products. See the applicable product Safety Data Sheet (SDS) for additional information. The potential exists that selling mercury or mercury-containing products, or both, is prohibited by local or national law. Users must determine legality of sales in their location. 1.10 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.11 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 This test method determines the effectiveness of UVGI devices for reducing viable microorganisms deposited on carriers. 5.2 This test method evaluates the effect soiling agents have on UVGI antimicrobial effectiveness. 5.3 This test method determines the delivered UVGI dose.
