SEEDS GENERALLY
Section 587.180 - Samples: Generally

1. In order to secure a representative sample, equal portions must be taken from evenly distributed parts of the quantity of seed or screenings to be sampled. Access must be had to all parts of that quantity. When more than one trierful of seed is drawn from a bag, different paths must be followed. When more than one handful is taken from a bag, the handfuls must be taken from well separated points.

2. For free flowing seed in bags or bulk, a probe or trier must be used. For small free flowing seed in bags, a probe or trier long enough to sample all portions of the bag should be used.

3. Nonfree flowing seed, for example, certain grass seed, uncleaned seed or screenings difficult to sample with a probe or trier, must be sampled by thrusting the hand in the bulk and withdrawing representative portions. The hand is inserted in an open position and the fingers are held closely together while the hand is being inserted and the portion withdrawn.

4. As the seed or screenings are sampled, each portion must be examined. If there appears to be a lack of uniformity, the portions must not be combined into a composite sample, but retained as separate samples or combined to form individual container samples to determine such lack of uniformity as may exist.

5. When the portions appear to be uniform, they must be combined to form a composite sample.
