experimental test data are presented which demonstrate that an increase in the fabric- or assembly-heat sensor separation improved protection against convective heat (flames) exposure. zirpro wool assemblies required a longer exposure time to reach second-degree burns, with a longer pain-alarm time than comparable assemblies of aramid or flame-retardant cotton. an increase in the weight of zirpro wool fabrics decreased heat transfer, but an assembly of a zirpro wool woven outerwear and a zirpro wool knitted underwear fabric transferred significantly less heat than a single layer of a zirpro wool woven fabric of comparable weight with the assembly, because of entrapped air in the thicker innerwear. with decreasing imposed heat flux, time for second-degree burns and pain-alarm time was increased, especially in the case of zirpro wool. 10 refs
