Individuals working in hot environments experience an increase in body core temperature due to the combined influences of physical activity, which elevates metabolic ,heat, production, and external ,heat, sources, which impede ,heat, loss. Since dry ,heat, exchanges are dependent upon ,thermal, gradients, then hotter environments restrict ,heat dissipation,, particularly when the air temperature ...

Clothing, insulation is the ,thermal, insulation provided by ,clothing,.. Even if the main role of ,clothing, is to protect from the cold, ,protective clothing, also exists to protect from ,heat,, such as for metallurgical workers or firemen. As regards ,thermal, comfort, only the first case is considered.

This study was designed to investigate the relationship between the microclimate temperature and ,clothing, insulation (I cl ) under comfortable environmental conditions. In total, 20 subjects (13 women, 7 men) took part in this study. Four environmental temperatures were chosen: 14°C (to represent March/April), 25°C (May/June), 29°C (July/August), and 23°C (September/October).

Total Heat Loss (THL) | Globe Turnout Gear

Generally speaking, the total ,heat, loss test has an inverse relationship with the ,thermal protective, performance (TPP) rating of a three-layer system. This actually makes sense when you consider that the way to obtain higher ,thermal, performance is to increase the ,thermal, insulation, while the way to allow more ,heat, to escape from a garment would be to decrease the ,thermal, insulation.
