Résumé
Relates to fabrics, fabric assemblies and fleeces. Applies to materials whose thermal resistance is within about 0.2 m^2·K/W to 2.0 m^2·K/W. This value of resistance is obtained by measuring the energy required to maintain an invariable difference of temperature in a heating body covered with the fabric to be tested as compared with the ambient temperature. Details of heating body are described and are shown in figures.
