4.4 Selection of sample bearings and preparation of test specimens.
4.4.1 Statistical selection of samples. Whenever a visual, and dimensional, and hardness examination of a lot
of bearings/staves is required, the sample shall be obtained by statistical sampling. Bearings/staves shall be selected
from each lot in accordance with Table VI. The bearings shall be visually inspected (see 4.5.1), dimensionally
inspected (see 4.5.2), and hardness tested (see 4.6.1) to verify compliance with this specification.

NOTE: Unless otherwise specified (see 6.2), any bearing/stave in the sample
containing one or more visual, dimensional, or hardness defect shall be
rejected and 100% inspection of all bearings/staves for that particular test is
mandated.
