This document is one part of a series of Technical Specifications that provide information on factors related to human anthropometry, physiology, ergonomics and performance for the preparation of standards for design, testing and use of respiratory protective devices. This document contains information related to thermal effects of respiratory protective devices on the human body. In particular information is given for:<\/p>\n
temperatures of surfaces associated with discomfort sensation and harmful effects on human tissues;<\/p>\n<\/li>\n
thermal effects of breathing gas temperatures on lung airways and tissues;<\/p>\n<\/li>\n
effects of breathing gas temperature and humidity on respiratory heat exchange;<\/p>\n<\/li>\n
effects of respiratory protective devices on overall body heat exchange.<\/p>\n<\/li>\n<\/ul>\n
The information represents data for adult healthy men and women in the age 20 years to 60 years.<\/p>\n
