Scope

This Part of GB/T 3074 specifies determination principles, instruments and
equipment, specimen preparation, test steps and results calculation for the
coefficient of thermal expansion of graphite electrodes.
This Part is applicable to the coefficient of other solid carbon materials of which
the ordinary power, high power, ultra-high-power graphite electrode and total
expansion at 600°C does not exceed 1mm, of which the temperature range is
room temperature ~ 600°C. If it needs to test the coefficient of thermal
expansion in other temperature ranges, it may refer to this method.
