This Part replaces GB/T 15072.13-1994 "precious metals and their alloys - Silver alloys Determination of cerium content of."
This section compared with the GB/T 15072.13-1994, have the following main changes.
--- Standard name from "precious metals and their alloys - Silver alloys Determination of cerium content of" to "precious metal alloys stars
Analytical methods of Tin silver, cerium and lanthanum content - Inductively coupled plasma atomic emission spectrometry ";
--- By inductively coupled plasma atomic emission spectrophotometry replace the original criteria used spectroscopy;
--- The scope of the original standard method AgCe0.5 alloy extended to AgCe, AgSnCeLa, AgCuSnCe,
AgCuNiCe series alloys, which AgSnCeLa, AgCuSnCe, AgCuNiCe for the new series;
--- Cerium measurement range (mass fraction) from 0.3% to 0.7% expands to 0.2% to 2%;
--- Increased lanthanum, tin element simultaneous determination of measurement range (mass fraction) of 0.2% to 2%;
--- Repeatability and allows the use of relatively poor poor allowed to replace the original criteria used.
