scope:

This part of the standard describes a method for the determination of the linear thermal expansion characteristics of advanced monolithic technical ceramics up to a maximum temperature of 1500 °C (see 5.2) and to a specified level of accuracy A or B as defined in table 1. The method describes general principles of construction, calibration and operation of suitable apparatus. Specific details, including test piece dimensions, depend on the design of the apparatus. Methods of calibration are given in annexes A and B. Thermal expansion reference data are given in appendix C.
