1.1 These practices are intended to provide the nuclear industry with procedures for obtaining representative bulk samples from uranium-ore concentrates (UOC) (see Specification C967).
1.2 These practices also provide for obtaining a series of representative secondary samples from the original bulk sample for the determination of moisture and other test purposes, and for the preparation of pulverized analytical samples (see Test Methods C1022 and C1843).
1.3 These practices consist of a number of alternative procedures for sampling and sample preparation which have been shown to be satisfactory through long experience in the nuclear industry. These procedures are described in the following order.
| Stage | Procedure | Section |
|
|
|
|
| Primary Sampling | One-stage falling stream | 5 |
|
| Two-stage falling stream | 6 |
|
| Auger | 7 |
| Secondary Sampling | Straight-path (reciprocating) | 8 |
|
| Rotating (Vezin) | 9, 10 |
