This is Part 10 GB/T 4103's.

This Part replaces GB/T 4103.10-2000 "of lead and lead alloys - Determination of silver content", and GB/T 4103.10- Compared to 2000, the main changes are as follows.

--- Additional fire assay Determination of silver content;

--- Measuring range extended from 0.0003% to ~ 1.5 to 0.0003% to 2.0%, by flame atomic absorption spectrometry - 0.0003% Adjusted 1.5% to 0.0003% to 0.50%, measured fire assay ranges from > 0.50% to 2.00%;

--- Supplementary terms of precision.

The non-ferrous metal part by the National Standardization Technical Committee (SAC/TC243) centralized.
