Description / Abstract: The method deals with the measurement of the change of length of a glass fibre under specified conditions. The apparatus including the used dilatometers and the possibilities of corretion, the formulae for the final length and the expansion coefficient are specified. In the annex, devices for self-adjusting alignment of specimen and push-rod axis are described and illustrated.
