Cleaning

  1. Divide a representative portion of at least 750 g from the uncleaned sample
  2. Sift the representative portion over the No. 4.5 round-hole sieve to remove up to 1% by weight of small weed seeds, chaff and dust.
    If more than 1% of small seeds, chaff and dust passes through the No. 4.5 round hole sieve,
    1. Assess dockage.
    2. Record dockage to the nearest 0.1%.
  3. Handpick soft earth pellets from the cleaned sample.
    • For samples containing up to 10% by weight of soft earth pellets, assess earth pellets as dockage.
    • For samples containing over 10% soft earth pellets by weight, grade Sample Screenings, Account Earth Pellets.
  4. Show the composition in detail on all records for carlots and cargoes.
