GB/T 10574.7-2017 《Methods for chemical analysis of tin-lead solders—Part 7：Determination of silver content—Flame atomic absorption spectrometry and potassium thiocyanate potentiometric titration》 Related products

This standard specifies methods for the determination of silver content in tin-lead solders, covering flame atomic absorption spectroscopy (AAS) and potassium thiocyanate potential Titrimetric method. The flame atomic absorption spectroscopy (AAS) method is suitable for the determination of silver content from 0.0020% to 0.500%, while the potassium thiocyanate potential Titrimetric method is suitable for the determination of silver content from 0.500% to 5.00%. The standard provides detailed procedures and reagent requirements for the accurate analysis of silver content in tin-lead solders, and is an important technical document for arbitration analysis.
