ASTM E362-99 PDF Download

For the chemical examination of these alloys, instructions are provided in the ASTM E362-99 standard. The standard outlines the maximum concentrations for elements like arsenic, carbon, chromium, lead, manganese, molybdenum, nickel, phosphorus, silicon, sulfur, and tin, as well as the chemical composition limitations for silicomanganese and ferrosilicon manganese.

The standard offers two test procedures for figuring out how much lead and arsenic are in these alloys. The Molybdenum Blue Photometric Method, the first technique, measures the amount of arsenic present at concentrations between 0.002 and 0.06%. Lead concentrations between 0.02 and 0.05% are measured using the second technique, the Dithizone Photometric Method.

These test procedures are crucial for making sure that silicomanganese and ferrosilicon manganese alloys meet the required chemical composition limitations and are of high quality. These guidelines improve the overall safety and effectiveness of these alloys in a variety of applications by precisely calculating the quantities of lead and arsenic.
