ASTM F2894 - Heat Resistance

ASTM F2894, Standard Test Method for Evaluation of Materials, Protective Clothing and Equipment for Heat Resistance Using a Hot Air Circulating Oven, and ISO 17493, Test Method for Convective Heat Resistance using a Hot Air Circulating Oven, are commonly used methods to evaluate the heat resistance and thermal shrinkage of flame resistant clothing. Materials are placed into an oven at 260°C (500°F)and evaluated for melting and dripping, ignition, separation and shrinkage. ASTM F2894 is one method cited by NFPA 2112.
