(1) Isolation - A field producing any class of certified seed must be at least fifty feet from any other variety or fields of the same variety that do not meet the varietal purity requirement for certification.

(2) Poor stands, poor vigor, lack of uniformity, excess weeds, or conditions which are apt to make inspection inaccurate or bring certified seed into disfavor shall be cause for rejection.

(3) Field standards are as follows:

	Maximum permitted in each class
Factor	Foundation	Registered	Certified
Other varieties*	1:5000	1:2000	1:1000
Other inseparable crops	None	0.05%	0.10%

*	Other varieties shall be considered to include plants that can be differentiated from the variety being inspected. However, other varieties shall not include variations which are characteristic of the variety being tested.
	Fields must be free of prickly lettuce, fanweed, and shepherds purse.
	Fields will be inspected at full bloom. Fields swathed prior to inspection are not eligible for certification. Conditions such as poor stand, excessive weeds or insect damage that prevent varietal determination may be cause for rejection.
