slotted or double tube, or slotted tube and rod, all with pointed ends.
Take >500 g sample, 1 kg preferred, as follows: Lay bag horizontally and remove core
diagonally from end to end. Determine number of cores as follows: From lots of 1-10 bags,
sample all bags; from lot of >11, sample 10 bags. Take 1 core from each bag sampled, except
that for lots of 1-4 bags take enough diagonal cores from each bag to total > 5 cores. For bulk
feed draw > 10 cores from different regions; in sampling small containers 1 sample is enough.
Reduce composite sample to amount required, preferably by riffling, or by mixing thoroughly on
clean oil cloth or paper. Place sample in air tight container.
A sample from less than these numbers of bags may be declared official if guarantor agrees. For
samples that cannot be representatively taken with probe described, use other sampling means.
ProcedureUse
Using slotted single or double or slotted tube and rod, all with pointed ends, take 500g. minimum. If representative bulk sample cannot be taken with probe described, other probes may be used if guarantor agrees.
