With the plethora of commercially available UV-C devices exhibiting different intensity and lifespans, it is critical to consumer safety that companies verify and clearly communicate the efficacy of their devices as per the intended use. The purpose of this study was to define a low-cost protocol for investigating the antimicrobial efficacy of commercial UV devices for industry use. The tested devices included: a wall-mounted unit (Device A), a troffer unit (Device B), and an induction lamp unit (Device C). The devices were installed within an enclosed tower to prevent the transmission of UV-C radiation outside of the testing area. The procedure details determining the devices' antimicrobial efficacy using plastic coupons inoculated with or The protocol includes suggested time-distance treatments according to the potential application of each device type and reports the results as log CFU/mL reduction or percent reduction.
由于市面上有大量不同强度和使用寿命的紫外线C设备，各公司按照预期用途验证并清晰传达其设备的功效对消费者安全至关重要。本研究的目的是定义一种低成本方案，用于调查工业用商用紫外线设备的抗菌功效。测试的设备包括：一个壁挂式装置（设备A）、一个吸顶式装置（设备B）和一个感应灯装置（设备C）。这些设备安装在一个封闭的塔内，以防止紫外线C辐射传播到测试区域之外。该程序详细说明了使用接种了……或……的塑料试片来确定设备抗菌功效的方法。该方案包括根据每种设备类型的潜在应用建议的时间-距离处理，并将结果报告为每毫升菌落形成单位（CFU/mL）减少对数或减少百分比。
