Peas – Chapter 16 | Official Grain Grading Guide
Net weight of sample
The sample after cleaning and removal of dockage is called the cleaned sample. Its weight is the net weight of the sample. Percentages by weight for grading of peas for human consumption refer to percentages of the cleaned sample, or the net weight.
Gross weight of sample
The sample as it arrives is referred to as the uncleaned sample. Its weight is the gross weight of the sample.
Percentages by weight for grading feed peas refer to percentages of the uncleaned sample, or the gross weight.
Hazardous substances in samples
Wear gloves and a mask to handle any samples that you suspect may contain hazardous substances. Hazardous substances are defined in the Regulations as “any pesticide, herbicide, dessicant or inoculant.”
Where grain of any kind is not a registered variety under the Seeds Act, no person shall, except with the permission of the Canadian Grain Commission, assign a statutory grade to that grain which is higher than the lowest grade established by regulation for that kind of grain. An order is issued annually to allow non-registered varieties of Peas to be graded higher than the lowest statutory grade.
Representative portion sizes for grading
All grading of human consumption peas is done on representative portions divided down from the cleaned sample, using a Boerner-type divider.
All grading of feed peas is done on representative portions divided down from the gross sample, using a Boerner-type divider.
The terms “Minimum” and “Maximum” refer to the range of sample portion size to be analyzed when an objective factor is present. The optimum representative portion (see glossary) is determined by taking into consideration the tolerance and concentration of the objective factor being assessed.
