Heat Transmission Measurements

The international group of papers in this volume covers representative subjects in the areas of fundamental studies of heat transmission processes, experimental techniques, both large and small scale, and the measurement and analysis of particular materials or systems for specific applications. The wide variety of subjects discussed, especially the Subcommittee Cl6.30 position paper which outlines their future philosophy, should stimulate further activities. The international representation of authors produces a further cross-fertilization of ideas which ultimately promotes greater international cooperation. One particu Alar area concerns that of the well characterized reference materials of low thermal conductivity being made available in the future. The Appendix briefly outlines how Subcommittee C 16.30 has started the work to solve the problem.
