Literature data on the thermal conductivity of commercially Dure aluminum, copper, iron, and tunqsten specimens have been collected, coded, critically analyzed, and correlated with analytical techniques based on theoretical and empirical equations. The resulting functions are presented and used to qenerate tables and graphs of thermal conductivity as a function of temperature and residual resistivity ratio (RRR). An annotated biblioqraphy of references is included. Discussions are included on the variations in thermal conductivity caused by chemical impurities, physical defects, size effects, and maqnetic fields. Smoothed values are presented for temperatures from 1 K to near the melting point and for a large ranqe of RRR val ues.

The thermal conductivities of three specimens of glass fiber/epoxy composites were measured and reported for the temperature range 4 to 300 K. These specimens were fabricated from two cryogenic dewar support bands. An average conductivity curve for the three specimens is presented.The data for the three specimens are within _+5% of this average curve.The average curve is compared to a similar curve obtained five years ago in Phase I of this continuing study of composite materials.

A brief review given of temperature scales, their definition, and measurement. Methods of practical temperature measurement are described. Differences between internationally accepted temperature scales are presented graphically and in tabular form; comparisons are also given for several national temperature scales. Emphasis has been placed on temperatures below 0°C, but some information on temperatures above 0°C has also been included. Suggested methods of conversion between different temperature scales are described.
