新型冠状病毒 SARS-CoV-2 通过人传人传播的风险最高，这推动了全球范围内个人防护设备的使用。在欧洲，医用口罩必须经过测试，以证明其基本要求符合欧洲标准 EN 14683:2019，工业用口罩必须符合欧洲标准 EN 149:2009。由于冠状病毒爆发对医用和非医用口罩的大量需求，意大利多个行业正在努力将部分产能转移到生产医用和非医用口罩。为了筛选评估改造后的工业生产的个人防护装备的有效性，拉齐奥高级研究计划局和托尔维加塔大学化学科学与技术系建立了一个分析系统，能够模拟呼吸动作，并使用光学粒子计数器测量穿过口罩的颗粒百分比（基于EN 16890：2017，使用相同的光散射原理来评估过滤器的过滤效率）。使用重新改造的行业生产的口罩对这一设置提出了挑战，并将数据与使用医用口罩获得的数据进行了比较。
The highest risk of novel coronavirus SARS-CoV-2 to be spread through human-to-human transmission has boosted the use of personal protective equipment at worldwide level. In Europe, the medical face masks must be tested to certify the essential requirements in agreement with European Standard EN 14683:2019, and face masks for industrial use in agreement with European Standard EN 149:2009. Due to the need of large quantitative of medical and non-medical face masks in coronavirus outbreak, several Italian industries are working for shift a portion of their manufacturing capacity for producing medical and non-medical face mask. For screening evaluation of the effectiveness of personal protective equipment produced by reconverted industries, ARPA Lazio and the Department of Chemical Science and Technologies of Tor Vergata University have set-up an analytical system able to simulate the respiratory action and to measure the percentage of particles that pass through the face masks using optical particle counter (based on the EN 16890: 2017 that uses the same light scattering principle to evaluate the filter filtration efficiency). This set-up was challenged using face masks produced by reconverted industries and the data were compared with ones obtained using medical face mask.
