Convective Heat Transfer and Hot Air Resistance
topic
Convective heat protection testing directs a heated air stream at controlled temperature and velocity through or over a fabric specimen while measuring transmitted heat flux with a calorimeter, calculating the convective heat transfer coefficient and protection time against hot air exposure hazards.
Role
Essential for evaluating fire proximity suits, bakery workwear, and industrial heat protective garments where convective hot air rather than radiant or contact heat is the primary thermal hazard, required by EN ISO 9151 certification protocols.
