MIL-S-851D
5 minutes +/- 5 seconds when a nominal sieve size of 35 or coarser is used. For nominal sizes finer than 35 sieve, shaking shall continue for 10 minutes +/- 50 seconds. After shaking, the percentage of material on each screen shall be determined by weighing.
4.3.5.1.1 Interpretation of screening results. Any two identical numbered U.S. Standard Test Sieves can give different weight percent results for the same shot sample because of the tolerance on average opening size permitted by RR-S-366 (and ASTM E 11 referenced therein). Tables II and III define grit and shot sizes in terms of such sieves. Therefore, the weight percent requirements expressed in these tables apply even under adverse tolerance conditions of test sieve average opening size. For example, in Table III the "Max. 5% On Screen" applies in conjunction with the smallest, and "Cumulative Min. 85% On Screen" applies with the largest average
opening sizes permitted by RR-S-366 for their respectively listed test sieves.
4.3.5.2 Size of cut wire shot. The size of as-cut steel wire shot as specified in 3.6.3, shall be determined as follows: ten random particles from each sample in 4.1.3, shall be metallographically mounted, ground, and polished to the centerline of the cylinder longitudinal section and the combined length of these ten particles measured for compliance with Table IV.
4.3.5.3 Weight of cut wire shot. The weight of cut steel wire shot either as-cut or conditioned as specified in 3.6.3 shall be determined as follows: Fifty particles selected at random from samples in 4.1.3 shall be weighed for compliance with the requirements of Table IV.
5. PACKAGING
5.1 Packing and palletizing. Packing shall be Level A, B, or C as specified (See 6.2). When specified, the containers for Level A or B shall be palletized in accordance with MIL-STD-147. When palletizing is specified for Level C, the pallet shall be the four way commercial expendable type.
5.1.1 Level A. For overseas shipment, the grit or shot shall be packed in unit quantities of 100 pounds in fiber drums conforming to PPP-D-723, Type III.
5.1.2 Level B. For domestic shipment and storage, the grit or shot shall be packed in unit quantities of 50 pounds in shipping sacks conforming to UU-S-48, Type II, Grade 15-15X.
5.1.3 Level C. For domestic shipment and immediate use, the grit or shot shall be packed in accordance with the suppliers commercial practice in a manner to assure protection against damage from the supply source to the first receiving activity. Shipping containers shall comply with the Uniform Freight Classification Rules, or regulations of other carriers as applicable to the mode of transportation.
5.2 Marking for Shipment and Storage shall be in accordance with MIL-STD-129.
