The Fodder Plant Seeds Regulations 1993

Obtaining submitted sample–composite sample division instruments

13.  Provided the composite sample is of at least the minimum weight prescribed in Part II below for a submitted sample for a particular kind of seed, it may be used as the submitted sample. Where the composite sample exceeds the weight prescribed for the submitted sample, any of the following instruments may be used to obtain the submitted sample. Other instruments and methods may be used at the discretion of the Minister.

(a) Riffle Divider

The riffle divider shall consist of a rectangular hopper leading to a series of evenly spaced chutes, arranged so that seed is distributed equally on two sides. There shall be a minimum of 18 chutes, each discharging in the opposite direction to its immediate neighbour.

• Three (or more) metal collecting vessels (pans) of sufficient depth to prevent seed bouncing out shall be used.

(b) Centrifugal Divider

The centrifugal divider shall consist of a hopper from which seed flows on to a shallow cup which is then rotated by an electric motor. The seed shall be distributed by centrifugal force onto a stationary baffle which divides it into two equal parts which are then discharged through separate spouts.

• Four metal collecting vessels (pans) of sufficient depth to prevent seed bouncing out shall be used.
