ASTM A835/A835M-84(2005)
(Specification)Standard Specification for Sizes of Ferroalloys and Alloy Additives
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 E 11. Representative procedures for evaluation of each lot are described in Methods A 610. Refer to for applicable sieve designations (see ).

it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

3.1.1 The sizes listed in Table 1 are typical as shipped from the manufacturer’s plant. Ferroalloys exhibit varying degrees of
friability; therefore, some attrition may be expected in transit, storage, and handling. A quantitative test is not available for rating
relative friability of ferroalloys.Acode system has been developed, therefore, for this purpose, and a number rating each product
type is given.
