ASTM A835/A835M-84(2010)

Standard Specification for Sizes of Ferroalloys and Alloy Additives

ABSTRACT
This specification covers standards for sizes of screened ferroalloys and alloy additives. Products shall conform to specified nominal size, standard ordered size, maximum allowable oversize, maximum allowable undersize, and friability rating. Description of the friability ratings of the ferroalloys is also provided.
SCOPE
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 X1 for applicable sieve designations (see Table X1.1).
