(3)

The presence of one seed of wild oats or darnel in a sample of the prescribed weight shallnot be regarded as an impurity where a second sample of the same weight is free from any seed of either of these species.

(4)

In basic seed, the nil standard shall apply only in respect of wild radish and corn cockle.
