Standard Test Methods for Sampling and Testing Ferroalloys for Determination of Size

Standard Details

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.

(A) The larger amounts are to be used for testing alloys of high specific gravity (50 % ferrosilicon and higher density); the smaller amounts are to be used for light alloys and metals (for example, calcium silicon and silicon metal).

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.
