6. Evaluation of thermal comfort of head gear : a method to measure heat transfer characteristics
Abstract : This study was carried out within the research project "Thermal properties of protective helmets - improvement, validation and standardization of a measurement method" which was a continuation of a research project being carried out since 1992 at the Division of Industrial Ergonomics, Department of Human Work Sciences, Luleå University of Technology, Sweden, with co-operation of the Department of Ergonomics, National Institute for Working, Life (NIWL), Solna, Sweden. A method was developed for measuring the evaporative heat transfer properties of helmets, based on the results of a thorough literature survey. READ MORE
