Gives two methods for determination of the thermal expansion of refractory materials. Applies to products fired to a temperature equal to or greater than the upper limit of intended testing, also can be used with oxidizable materials should the equipment be fitted with means to produce a reducing atmosphere. Maximum testing temperature is 1500 deg C.

This Section of BS 1902 : Part 5 describes two methods for determining the thermal expansion of refractory materials. The methods are applicable to products which have been fired to a temperature equal to or greater than the upper limit of intended testing, and may also be used with oxidizable materials if the equipment is fitted with means to produce a reducing atmosphere. The maximum temperature for testing is 1500 °C.
NOTE 1. The methods may be used to determine the dimensional changes occurring during heating of unfired materials, which is not usually described as thermal expansion.
NOTE 2. The titles of the publications referred to in this standard are listed on the inside back cover.
Appendix B gives the method for testing investment casting shell moulds. This method is for determination of both thermal expansion and contraction as a function of temperature and time, and is applicable to all shell mould test pieces whether in a green or fired condition.
