该方法涉及在特定条件下测量玻璃纤维长度的变化。规定了包括所用膨胀计和校正可能性、最终长度和膨胀系数的公式在内的装置。附录中描述并举例说明了试样和推杆轴自调整对准装置。

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.
