- Abstract
- A series of different material systems representing potential reinforced knee areas of firefighter protective garments were subjected to both conductive and radiant heat resistance testing. Conductive heat resistance testing of prepared garment knee samples was based on ASTM Test Method for Thermal Protective Performance of Materials for Protective Clothing for Hot Surface Contact (F 1060), and included repeated exposures to the same area of the sample seprated by wash/dry cycles to simulate use and wear of garments. Other knee samples were tested in accordance with ASTM Test Method for Radiant Protective Performance of Flame Resistant Clothing Materials (F 1939) at radiant heat fluxes of 8.4 and 84 kW/m representing ordinary and emergency fire ground conditions. For both types of testing, samples were tested under both dry and wet conditions. Time-to-pain and time-to-burn were measured in both series of tests using established calorimeter-based temperature thresholds.
