Fababeans – Chapter 21 | Official Grain Grading Guide
Determination of dockage
Dockage is not assessed on fababean samples that meet the commercially clean specifications set out in the Fababean Export Shipments section. All samples must be analyzed to determine if they meet commercial cleanliness standards prior to dockage being assessed. The analysis of samples which are clearly not commercially clean may consist of a visual assessment. For example, if there is no doubt that a sample contains more than 0.2% of foreign material then dockage will be assessed using the procedures defined under Determination of Dockage. Where there is any doubt regarding whether the sample is commercially clean the sample must be analyzed.
Dockage is assessed and recorded to the nearest 0.1%.
Dockage is defined under the Canada Grain Act as “any material intermixed with a parcel of grain, other than kernels of grain of a standard of quality fixed by or under this Act for a grade of that grain, that must and can be separated from the parcel of grain before that grade can be assigned to the grain.” Dockage is removed by following the cleaning procedures described in this section of the guide.
The sample as it arrives is referred to as the uncleaned or dirty sample. Its weight is the gross weight of the sample. Dockage is assessed on the gross weight of the sample.
Dockage not reported
Dockage is not reported for samples graded
- Fababeans, Sample Canada Account Fireburnt
- Fababeans, Sample Salvage
- Fababeans, Sample Condemned
Normal cleaning procedures
Wear gloves and a mask to handle any samples that you suspect may contain hazardous substances.
- Using a Boerner-type divider, divide the uncleaned sample to obtain a representative portion.
- Official samples shall be at least 1 kg.
- Unofficial samples shall be at least 1 kg.
- Choose the appropriate hand sieve for the size of fababean:
- No. 8 slotted
- No. 9 slotted
- No. 11 slotted
- Sieve the samples over the appropriate slotted sieve, using approximately 250 g at a time, to remove all readily removable material.
- Determine dockage, using the list under Composition of dockage.
Composition of dockage
- Material handpicked from the sieved sample, including all coarse vegetable matter such as pods, stems, straw, and thistle tops
- All material removed by sieving
- Important: Do not handpick mineral matter, ergot, sclerotinia, or large-seeded grains other than fababeans from the sieved sample.
- Soft earth pellets, if they are 10.0% or less of the uncleaned sample by weight
Commercially clean primary samples can have up to 0.75% for finely broken fababeans removed by the No. 8 slotted sieve as dockage is allowed. Primary samples are considered commercially clean when meeting the requirements set out in the table below;
|Grade name||Foreign material|
|Material passing through No. 8 slotted sieve, including handpicked material %||Total %|
|No. 1 Canada||0.1||0.2|
|No. 2 Canada||0.1||0.2|
|No. 3 Canada||0.1||0.2|
Where a shipper requests special cleaning of a carlot of grain at a terminal elevator, and the elevator manager agrees, dockage material will be analyzed for the presence of grain. The percentage and grade of any grain contained in the dockage will be reported.
- Analyze the official sample.
- Record the following on inspection records:
- The percentage by gross weight to the nearest 0.1% and the grade of fababeans.
- The percentage by gross weight to the nearest 0.1% and the grade of grain separable from dockage.
- The percentage of dockage.
95.0% Fababeans, No. 1 CAN
4.0% Domestic Mustard Seed, No. 1 CAN Oriental
