This Part replaces GB/T 15072.14-1994 "precious metals and their alloys - Silver alloys Determination of aluminum content."
This section compared with the GB/T 15072.14-1994, have the following main changes.
--- Name from "precious metals and their alloys - Silver alloys Determination of aluminum content" to "precious metal alloys -
- Silver alloy of aluminum and nickel content - Inductively coupled plasma atomic emission spectrometry ";
--- By inductively coupled plasma atomic spectrophotometry instead of the original criteria used emission spectroscopy;
--- The scope of the original standard method AgCuNiAl20-2-1 alloy extended to AgCuNiAl, AgCuNiCe, AgCuNi
And AgMgNi series alloys, which AgCuNiCe, AgCuNi and AgMgNi for the new series;
--- Aluminum measurement range (mass fraction) from 0.5% to 1.2% expands to 0.1% to 2.5%;
--- Nickel element increases the simultaneous determination of measurement range (mass fraction) of 0.1% to 2.5%;
--- Repeatability and allows the use of relatively poor poor allowed to replace the original criteria used.
