Scope

This part of GB/T 20975 specifies the method for determining the hydrogen content in solid aluminum and aluminum alloys by the thermal conductivity method of heating extraction.
This part is applicable to the determination of hydrogen content in solid aluminum and aluminum alloys. The measurement range is: 0.05 μg/g to 1.0 μg/g.
Note: This method has only undergone inter-laboratory testing for the specified measurement range. However, laboratories can extend the measurement range of this method through experiments such as method sensitivity, precision, and deviation when validating the method.
