Application analysis of standard YB/T 4174.3-2022 Analytical methods of calcium-silicon alloy-Part 3:Determination of calcium oxide content-Potentiometric titration method
The application of YB/T 4174.3-2022 Analysis method for calcium-silicon alloy-Part 3:Deter-mination of calcium oxide content-Potentiometric titration method in actual detection was comprehensively analyzed.The corresponding terms in chapters of"scope,reagents and materials,instrument,sampling and sample preparation,sample analysis,results calculation and expression,and precision"were discussed in de-tail.Meanwhile,the matters that should be paid attention in testing,the test method for acceptability of measurement results,the in laboratory repeatability,and inter-laboratory reproducibility were supplemen-ted and described.This study provided reference for the use of standard.
