5. Sampling
5.1 Gross Sample ofLoose Ferrous Scrap: 5.1.1 Take a minimum ofone gross sample having a volume of 7 ft 3 (0.2 m 3 ) (approximately equal to a 55-gal drum). Guidance for determining the number of gross samples needed to characterize a given lot of material and methods for accumulating a gross sample can be found in Practices E122 and D2234/D2234M, respectively. In all cases, the actual sampling procedures to be used and the number of gross samples required to obtain a representative sample of the lot shall be established in accordance with an agreement between the purchaser and supplier. 5.1.2 Air-dry the gross sample at ambient temperature for a period of 24 h by spreading the sample on a clean, dry surface to one-layer thickness. Protect the sample from contamination by falling dust and debris. Reduce the gross sample to four samples by the method of coning and quartering, as described in Method B of Practice C702/C702M. 5.2 Gross Sample of Baled Ferrous Scrap—Take a mini- mum of two bales. Guidance for determining the number of bales needed to characterize a given lot of material and methods for selecting the bales can be found in Practice E122. In all cases, the actual sampling procedures to be used and the number of gross samples required to obtain a representative sample of the lot shall be established in accordance with an agreement between the purchaser and supplier.
6. Bulk Density
6.1 Loose Ferrous Scrap: 6.1.1 Apparatus: 6.1.1.1 Container, constructed of suitable materials, for example, plywood, having the following approximate internal dimensions: base of 1 by 1 ft (300 by 300 mm) and a height of at least 2 ft (600 mm). Measure the internal dimensions of the box to the nearest 0.1 in. (3 mm). Suitable handles may be attached to the exterior of the container to aid in subsequent handling. Alternatively, containers of other geometries agree- able to the purchaser and supplier may be employed provided the area of the base is at least 1 ft 2 (0.09 m 2 ). N OTE 1—The operator should be aware that this test method is not intended for those occasional pieces whose size is of the order of the dimensions of the box. As a guide, the maximum length of a single piece should not exceed three-fourths of the maximum dimension of the base. 6.1.1.2 Balance or Scale, accurate within 0.1 % of the test load within the range of use. The range of use shall be considered to extend from the weight of the container empty to the weight of the container plus its contents at 100 lb/ft 3 (1600 kg ⁄m 3 ). 6.1.1.3 Measuring Rod, calibrated in 0.1-in. (3-mm) intervals, having a blunt end with an area of 4 in. 2 (26 cm 2 ). 6.1.2 Procedure: 6.1.2.1 Use each of the four samples from 5.1.2 to deter- mine the bulk density. 6.1.2.2 Before each determination, weigh the empty con- tainer to the nearest 0.1 lb (0.05 kg). 6.1.2.3 Place oversize pieces likely to protrude above the surface of the material in the container at the bottom of the container prior to filling with the remainder of the sample. 6.1.2.4 Fill the container in three approximately equal layers. After each layer, place the container on a firm base, for example, a concrete floor, raising the opposite sides alternately about 2 in. (50 mm) and allowing the container to drop in such a manner as to hit with a sharp, resounding impact. Do this settling step ten times, five times on each side, in the manner described. Level the surface of the material manually to minimize surface irregularities. 6.1.2.5 Using the measuring rod described in 6.1.1.3, mea- sure the distance from the top of the container to the surface of the material to the nearest 0.1 in. (3 mm) in each of the four corners of the container. Subtract the average of the four measurements from the inside height of the container to determine the height of the material. 6.1.2.6 Weigh the filled container to the nearest 0.1 lb (0.05 kg).
