These practices are intended to provide the nuclear industry
with procedures for obtaining representative bulk samples from
uranium-ore concentrates (UOC) (see Specification C967).
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
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.
It is possible to combine the various elements of these stages
in different ways to give satisfactory results depending on the
agreed requirements of the contracting parties. For a given stage,
however, each procedure must be regarded as a whole. It is highly
inadvisable to mix elements belonging to different procedures.
These procedures do not include requirements for health, safety,
and accountability. The observance of these practices does not
relieve the user of the obligation to be aware of and to conform to
all applicable international, federal, state, and local regulations
pertaining to processing, shipping, or using uranium-ore
concentrates. (Guidance is provided in CFR, 10, Chapter 1.)
