Determination of the thermal resistance of textiles. Two-plate method: fixed pressure procedure, two-plate plate method: fixed opening procedure, and single-plate method Ingestion-build-242630 ISO 6506:19811 Scope This part of BS 4745 specifies three methods for the determination of the resistance of fabrics, fabric assemblies or fibre aggregates in sheet form to the transmission of heat through them in the steady state condition. rt applies to materials whose thermal resistance is up to approximately 0. 2 m2K W. These methods are suitable for materials up to 20 mm thick (above this thickness, edge losses become appreciable). Advice on suitable
