呼吸器适配测试板提供了一种客观的工具，用于基于面部特征选择代表性的人类测试对象，以用于研究、产品开发、测试和认证。合身测试板通常基于人体测量数据，例如1967-1968年对美国军事人员的调查。在这项研究中，目的是：（i）评估最近开发的国家职业安全与健康研究所（NIOSH）的呼吸器适合性测试面板的适用性，为中国工人和（ii）开发新的呼吸器适合性测试面板使用中国的调查数据。总体而言，中国调查中95%的工人属于NIOSH双变量和主成分分析（PCA）面板，这表明这些面板也适用于中国人群。然而，受试者在小组中的分布并不均匀;只有6.3%的调查参与者属于二元小组的五个单元格，只有7.2%的人属于PCA小组的三个单元格。因此，具有针对中国工人的主题尺寸和分布的新的呼吸器适合性测试面板可能对某些应用有益。两个新的呼吸器适合性测试面板开发与用于创建NIOSH面板相同的技术。所有测量值都经过加权，以匹配2005年人口普查中中国人口的年龄和性别分布。双变量方法使用脸长和脸宽测量，PCA面板使用从一组10个面部尺寸获得的前两个主成分开发。为这些中国工人专用面板设计的呼吸器也可能适用于95%以上的中国工人。
Respirator fit test panels provide an objective tool for selecting representative human test subjects based upon their facial characteristics for use in research, product development, testing and certification. Fit test panels were typically based upon anthropometric data such as the 1967-1968 survey of American military personnel. In this study, the objectives were to: (i) evaluate the applicability of the recently developed National Institute for Occupational Safety and Health (NIOSH) respirator fit test panels for Chinese workers and (ii) develop new respirator fit test panels using the Chinese survey data. Overall, 95% of the workers in the Chinese survey fall within the NIOSH bivariate and principal component analysis (PCA) panels, suggesting that these panels would also be appropriate for the Chinese population. However, distribution of the subject across the panels was not uniform; only 6.3% of survey participants fell into five cells of the bivariate panel and only 7.2% were found within three cells of the PCA panel. Therefore, new respirator fit test panels with subject dimensions and distributions specific to Chinese workers may be beneficial for certain applications. Two new respirator fit test panels were developed with the same techniques used to create the NIOSH panels. All measurements were weighted to match age and gender distributions of the Chinese population from the 2005 census. The bivariate approach used face length and face width measurements, and the PCA panel was developed using the first two principal components obtained from a set of 10 facial dimensions. Respirators designed to fit these Chinese worker-specific panels are also likely to accommodate > 95% of Chinese workers.
