title: On the transition thermal discomfort to heat stress as a function of the PMV value.
abstract: ISO 15265 Standard - Ergonomics of the thermal environment - Risk assessment strategy for the prevention of stress or discomfort in thermal working conditions - can be considered as a key document for helping responsible for the health protection and prevention of working situations. According to the SOBANE strategy, this standard provides a three-step protocol aimed to the prevention, elimination or reduction of risks affecting the workplaces. Although both methods and procedures suggested by ISO 15265 appear very clear, this standard could bring in confusion both beginners and not specialists in occupational health concerning Predicted Mean Vote (PMV) threshold values consistent with comfort - hot discomfort and the discomfort - hot stress transitions. In this work such matter has been extensively discussed showing a certain difficulty in the definition of an unambiguous PMV threshold value for each working situation in any microclimate.
