Studies on the Allowance of the Chemical Analysis of Ferro-alloys by JIS Methods (II). Ferrosilicon

Abstract

The determination of several elements in ferrosilicon is increasing in importance with the newer developments in metallurgy. But often, there is a difference between the actual contents and its analytical values, caused by segregation or errors in the analytical procedure. This paper reports on the standard deviation (σ) for each method, and studies the results with reference to the allowance that is tolerated in practice.
