Sizing of yellow peas

In yellow peas only, size is part of the grade name, if size is determined as small or large, then size becomes part of the grade name. If a sample does not meet the definition for large or small, it is graded without reference to size.

1. Using a Boerner-type divider, divide a representative portion of 250 g.
2. Sieve the representative portion over the No. 14 round-hole sieve.
3. Determine the portion remaining on top of No. 14 round-hole sieve.

95% or more remains on top of No. 14 round-hole sieve	Less than 95% remains on top of No. 14 round-hole sieve
The sample is designated Large.	1. Recombine the sample.
	2. Sieve the sample over the No. 15 round-hole and No. 11 round-hole sieves.
	3. Determine the portion passing through the No. 15 round-hole sieve.
	90% or more passes through the No. 15 round-hole sieve		Less than 90% passes through
	Determine the amount that remains on top of the No. 11 round-hole sieve.		Graded without reference to size
	95% or more	Less than 95%
	The sample is designated Small.	Graded without reference to size
