21. Where the composite sample exceeds the minimum weight prescribed for a sample in paragraph 26 of Part II of this Schedule, any of the following instruments may be used to reduce the weight of the sample–
(i)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;
(ii)there shall be a minimum of 18 chutes, each discharging in the opposite direction to its immediate neighbour; and
(iii)three (or more) metal collecting vessels (pans) of sufficient depth to prevent seed bouncing out shall be used;
(i)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; and
(ii)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; or
other instruments and methods may be used with the written approval of the Scottish Ministers.
