This specification covers standard methods for sampling and testing of various ferroalloys for size analysis. Ferroalloys are classified into lump and crushed or plates sizes. The small-sized samples subject to screen testing shall be taken from the lot sample by riffling, and larger sized samples by mixing and quartering. Sizing of lumps shall be done by visual examination. Crushed or plates materials shall be subjected to sieving by using either manually driven or mechanically driven screen vibrators to divide samples into several size fractions.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 These test methods cover procedures for the sampling and testing of the various ferroalloys for sizing, either before or after shipment from the plants of the manufacturers.

1.2 They are designed to give results representative of each lot that will be comparable with the manufacturer's certified analysis for the same lot.

1.3 The purchaser may use any sampling procedure he desires, but the results obtained on such samples shall not be a basis for complaint or rejection, unless the procedure followed is of an accuracy equivalent to that prescribed in these test methods.

1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.4.1 Exception—The SI units that correspond to mesh sizes in Table 1 are to be regarded as standard.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
