- Scope
- This standard specifies the method summary, reagents, instruments, analysis steps, drawing of working curves, calculation of analysis results and allowable differences for the determination of cerium content in high-temperature alloys using DBC-arsenazo absorptiophotometry. This standard is applicable to the determination of cerium content in high-temperature alloys (it refers to the case where the high-temperature alloy contains only cerium. When the high-temperature alloy contains mixed light rare earths mainly cerium, the measured value is the total amount of mixed light rare earths).
