In a wide range of temperatures from about 1 K to 4000 K, a wide variety of relative and absolute methods to measure thermal expansion is mentioned and special emphasis is placed on methods which allow high precision to be achieved and on procedures suitable for special sample shapes and short-time measurements, for example, of thermal instable materials. The experimental handling and marginal conditions are discussed. Evaluation and conversion in the case of differing references are presented. Check lists are given for planning measurements and for purchasing a commercial dilatometer. Three tables show available reference materials and the range of the thermal expansion of natural and technical materials.
