GB/T 13747.7-2019 《Methods for chemical analysis of zirconium and zirconium alloys—Part 7：Determination of manganese content—Patassium periodate spectrometry and inductively coupled plasma atomic emission spectrometry》 Related products

This standard specifies the determination method of manganese content in zirconium and zirconium alloys, which is applicable to the chemical analysis of sponge zirconium, zirconium and zirconium alloys. The methods include potassium periodate Spectrophotometric method, spectra-trophotometry and Inductance coupled plasma atomic emission spectroscopy (AES) method, the measurement range is 0.0010% to 0.40%. When the measurement ranges overlap, Inductance coupled plasma atomic emission spectroscopy (AES) method is the arbitration method.
