Abstract : Modifications to the direct heating apparatus to permit measurement of the thermophysical properties of shorter samples and of samples of anisotropic materials are discussed. The measurement of thermal linear expansion using the multiproperty apparatus is described and data are presented for a standard copper sample. Thermophysical property data for arc cast tungsten and for MOD-3 carbon to about 2600 K are given. These properties include the electrical resistivity, hemispherical total emittance, normal spectral emittance, and thermal conductivity for both materials, Lorenz function for tungsten and thermal linear expansion for MOD-3 carbon. Some data on Thornel 50 and Morganite II fibers are also presented. A brief analysis of digital data acquisition systems for the laboratory and a description of the system purchased by TPRC ARE INCLUDED. (Author-PL)
