ASTM A835-10(R2020) pdf free download.Standard Specification for Sizes of Ferroalloys and Alloy Additives
1. 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 Test Methods A610. Refer to Appendix X1 for applicable sieve designations (see Table X1.1). 1.4 Units—The values stated in either SI units or inch- pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently ofthe other. Combining values from the two systems may result in noncon- formance with the standard. 1.4.1 This specification is expressed in both inch-pound units and in SI units (within the text, the SI units are shown in brackets); however, unless the purchase order or contract specifies the applicable M specification designation (SI units), the inch-pound units shall apply. 1.5 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3. Dimensional Requirements
3.1 Screened products shall conform to the sizes given in Table 1. 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 avail- able for rating relative friability of ferroalloys. A code system has been developed, therefore, for this purpose, and a number rating each product type is given. N OTE 1—For further description of friability ratings for ferroalloys, refer to Appendix X2.
