NIOSH Anthropometric Data and ISO Digital Headforms

In 2003, the National Institute for Occupational Safety and Health (NIOSH) conducted a nationwide anthropometric survey of 3,997 subjects. The resulting head and face measurements were used to develop an anthropometric database detailing the face size distributions of respirator users using both traditional measurement methods and three-dimensional (3D) scanning systems. This database was used to establish fit test panels to be incorporated into NIOSH respirator certification and international standards. One of the panels developed, called the principal component analysis (PCA) panel, uses the first two principal components obtained from a set of 10 facial dimensions (age and race adjusted) and divides user population into five face-size categories. These 10 dimensions are associated with respirator fit and leakage and can predict the remaining face dimensions as well. Respirators designed to fit these panels are expected to accommodate more than 95% of the current U.S. civilian workers. From the 3,997 subje2003年，美国国家职业安全与健康研究所（National Institute for Occupational Safety and Health，NIOSH）针对3997名受试者开展了全国性人体测量学调查。研究所得的头面部测量数据被用于构建人体测量数据库，该数据库结合传统测量方法与三维（3D）扫描系统，详细记录了呼吸防护用品使用者的面部尺寸分布特征。该数据库被用于构建适配测试面板，相关面板将被纳入NIOSH呼吸防护用品认证体系与国际标准。其中一款研发完成的适配测试面板为主成分分析（principal component analysis，PCA）面板，其基于经年龄与种族校正的10项面部维度所提取的前两个主成分，将使用者群体划分为5个面部尺寸类别。这10项面部维度均与呼吸防护用品的适配性能及泄漏情况相关，同时也可用于预测其余未纳入的面部维度。适配该类面板设计的呼吸防护用品，预计可覆盖当前美国民用劳动者群体中95%以上的人群。从本次研究的3997名受试者

背景概述

该数据集包含美国国家职业安全卫生研究所（NIOSH）在2003年对3997名受试者进行的头面部人体测量数据，用于建立呼吸器使用者面部尺寸分布数据库，并基于主成分分析（PCA）将用户分为五个面尺寸类别，旨在支持呼吸器认证和国际标准，预期可覆盖95%以上的美国民用工人。
