This section GB/T 10574 Part 12.
This section drafted in accordance with GB/T 1.1-2009 given rules.
This Part replaces GB/T 10574.12-2003 "Determination of sulfur content of tin-lead solder chemical analysis." This section and
GB/T 10574.12-2003 compared to the main technical changes are as follows.
--- Increasing the normative references;
--- Determination range from 0.0002% to 0.030% adjusted to 0.00010% ~ 0.025%;
--- The amount of sample is adjusted from 0.5g to 0.20g, 0.50g and 1.0g;
--- Co-solvent from tin and tin tungsten co-solvent changed to iron and tungsten co-solvent;
--- Crucible pretreatment temperature from 1100 ℃ to 1350 ℃;
--- High-frequency infrared carbon and sulfur analyzer sulfur detector sensitivity from 0.0001% to ≤ 0.000001%;
--- Sulfur standard by tin-lead solder standard sample or tin standard sample changed to sulfur standard solution;
--- Increasing the oxygen purity requirements;
--- Precision from the allowable error to modify the repeatability and reproducibility of the content.
This part is proposed by China Nonferrous Metal Industry Association.

3 method summary
In the presence of a flux, the sample is heated and combusted in a stream of oxygen in a high frequency induction furnace and the resulting sulfur dioxide is carried from oxygen to infrared
Measuring room of the device. Sulfur dioxide absorbs infrared energy at a specific wavelength, its absorbance is proportional to the mass of sulfur, derived from the absorbance of sulfur
quality.
