This European standard describes a thermophysiological model (thermal
human simulator) that uses the output data of the first part to obtain
physiological heat load criteria that predicts the (maximal) duration of
work in the protective clothing in fire fighters’ relevant conditions.
NOTE The human simulator method using the Sweating Torso (i.e.
coupling of the instrumented manikin with a thermo-physiological
feedback model) is validated for different scenarios by comparison to
human subject trials(1, 2). The scenarios also included warm and hot
environments as can be expected for firefighter applications. Core
temperature, being one of the most important physiological variables,
and mean skin temperature, which is a useful indicator of thermal comfort
sensation and of the overall condition of the body, are chosen as relevant
physiological parameters for the thermophysiological human simulator.
