On the occasion of a judicial expert opinion on the question of whether wearing a face mask can lead to a falsification of the breath alcohol value leading to detriment of the accused, an experimental series of tests was carried out under pandemic conditions on six healthy test subjects (four men, two women), who practiced low-risk recreational alcohol consumption. On each day of the study one specific mask type (surgical mask, textile mask, FFP2 mask) was examined. After ingestion of an individually calculated amount of alcohol and a 30-min absorption phase, 6 consecutive breath alcohol measurements were carried out at 30-min intervals, with one mask or no mask worn between measurements. Subsequently, pairs of values for periods with and without a mask were formed and the hourly breath alcohol elimination rates were calculated. As a result, the breath alcohol elimination rates with and without masks did not differ from each other. There were no error messages from the breathalyzer that can be attributed to the previous wearing of a mask.
在就佩戴口罩是否会导致呼气酒精值被篡改从而损害被告利益这一问题进行司法专家意见评估时，在疫情条件下对六名健康的受试对象（四名男性，两名女性）进行了一系列实验测试，这些受试对象有低风险的娱乐性饮酒行为。在研究的每一天，对一种特定类型的口罩（外科口罩、纺织口罩、FFP2口罩）进行检测。在摄入单独计算的酒精量并经过30分钟的吸收阶段后，每隔30分钟连续进行6次呼气酒精测量，测量期间佩戴一种口罩或不戴口罩。随后，形成有口罩和无口罩时期的成对数值，并计算每小时的呼气酒精消除率。结果，戴口罩和不戴口罩时的呼气酒精消除率没有差异。呼气酒精测试仪没有发出可归因于之前佩戴口罩的错误信息。
