The work of the main European research teams in the field of thermal factors was coordinated in order to improve significantly the Required Sweat Rate model published as an international standard. Many significant modifications were brought, in particular concerning the effects of forced convection, body movements and exercise and the prediction of the skin temperature as a function of the rectal temperature and in case of severe conditions of radiation, humidity and clothing. The criteria for acceptable work durations in hot environments were updated concerning the maximum increase in core temperature and the acceptable water loss. The revised model, called Predicted Heat Strain model, was validated through a set of lab and field experiments involving stable and fluctuating conditions with high and low radiation, humidity and air velocity. It is meanwhile adopted as an ISO and CEN standard. In addition, a strategy was developed to assess the risks of heat disorders in any working situation. It is based on the three highest stages of the SOBANE strategy: an "Observation" method for improving simply the thermal conditions of work; an "Analysis" method to evaluate the magnitude of the problem and optimise the choice of solutions and an "Expert" method for in depth analysis of the working situation when needed.

:协调了主要的欧洲研究团队在热因素领域的工作,以便显着改善作为国际标准发布的“要求的出汗率”模型。带来了许多重要的改进,特别是关于强制对流,身体运动和运动的影响以及根据直肠温度以及在严重的辐射,湿度和衣服条件下皮肤温度的预测。更新了高温环境下可接受的工作时间标准,有关核心温度的最大升高和可接受的水分流失。经过修订的模型称为预测的热应变模型,已通过一组实验室和现场实验进行了验证,这些实验涉及稳定和波动的条件,以及高低辐射,湿度和空气速度。同时,它被用作ISO和CEN标准。此外,还制定了一项策略来评估在任何工作情况下发生热病的风险。它基于SOBANE策略的三个最高阶段:“观察”方法,用于简单地改善工作的热工条件;一种“分析”方法,用于评估问题的严重程度并优化解决方案的选择;另一种“专家”方法,用于在需要时对工作状况进行深入分析。
