• The intentional addition of Bi, Se, Te, and Pb is not permitted except for Grades 6F, 8F, and 8FA, in which Se is specified and required.
• Total aluminum, soluble and insoluble.
• Because of the degree to which sulfur segregates, product analysis for sulfur over 0.060 % max is not technologically appropriate.
