Standard Test Method for Thermal Transmittance of Textile Materials

This test method measures the thermal resistance of battings and batting/fabric systems under steady-state conditions by evaluating heat transfer from a warm plate to a cool atmosphere, either in still air or with airflow. The method applies to materials with thermal resistance between 0.1 and 1.5 K·m²/W and thicknesses up to 50 mm, also assessing bulk density, insulation per unit thickness, and insulation per unit weight.
