1.1 This specification covers standard nominal sizes and size tolerances of screened ferroalloy and alloy additive products. This specification provides a range of sizes as referenced in all ASTM specifications for ferroalloys and alloy additives.
1.2 The sizes and tolerances allow for varying degrees of friability upon receipt of material since some attrition may be expected in transit, storage, and handling.
1.3 Specifications of sieve sizes used to define tolerances are listed in Specification E11. Representative procedures for evaluation of each lot are described in Methods A610. Refer to Appendix
ICS Number Code 77.100 (Ferroalloys)
