Screenings: Mixed feed oats
Cleaning
- Divide a representative portion of at least 750 grams (g) from the uncleaned sample.
-
Sift the representative portion over the numberNo. 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 numberNo. 4.5 round hole sieve:
- Assess dockage.
- Record dockage to the nearest 0.1%.
- Handpick soft earth pellets from the cleaned sample.
- For samples containing up to 10% by weight of soft earth pellets (SEP), assess earth pellets as dockage.
- For samples containing over 10% soft earth pellets by weight, grade ‘Sample Screenings, Account Earth Pellets’.
- Show the composition in detail on all records for carlots and cargoes.
