Describes a method for determining the steady-state thermal resistance, conductance, conductivity and resistivity of homogeneous insulating solids in slab form from -20 Degrees C to 100 Degrees C using the 305 mm unguarded hot-plate apparatus. Covers definitions, principle, laboratory environment, apparatus, test specimens, procedure, edge-loss correction, expression of results and test report.
