What this standard covers
This standard specifies the method for determining the rhenium content in tungsten-rhenium alloy by spectrophotometry and inductively coupled plasma atomic emission spectrometry. This standard is applicable to the determination of rhenium content in tungsten-rhenium alloy. The determination range (mass fraction) of spectrophotometry is 0.50% to 5.00%, and the determination range (mass fraction) of inductively coupled plasma atomic emission spectrometry is 0.50% to 28.00%. For the overlapping determination ranges, spectrophotometry is used as the arbitration method.
