Estimates of Thermal Conductivity for Materials Used in Fire Fighters' Protective Clothing
Fire fighters' protective clothing provides a limited amount of thermal protection from environmental exposures produced by fires. This level of thermal protection varies with the design, materials, construction, and fit of the protective garments. This report presents thermal conductivity data for nine materials used in fabricating fire fighters' protective clothing. These materials included outer shell fabrics, moisture barrier, thermal linear batting, and reflective trim. As a comparison, measurements were also made on a cotton duck fabric. The thermal conductivity of individual protective clothing materials was measured using the test procedure specified in ASTM C-518 Standard Test Method for Steady-State Thermal Transmission Properties by Means of Heat Flow Meter Apparatus (1). Measurements producing estimates of thermal conductivity for single layers of materials were carried out at mean teat temperatures of 20 deg C (68 deg F), 48 deg C (118 deg F), 55 deg C (131 deg F), and 72 deg C (162 deg F). No visible physical changes were observed with any of the materials tested at these temperatures. Thermal conductivity estimates for materials used in the construction of fire fighters' protective clothing ranged from 0.034 W/mK to 0.136 W/mK over the range of temperatures addressed in the study. Generally, thermal conductivity values increased for all materials as mean test temperatures were increased.
