Section 02.06.01.112 - METHODS OF SAMPLING - GENERAL PROCEDURE01.Sample. In order to secure a representative sample, equal portions are taken from evenly distributed parts of the quantity of seed or screenings to be sampled with access to all parts of that quantity. When more than one (1) trierful of seed is drawn from a bag, different paths will be followed. When more than one (1) handful is taken from a bag, the handfuls will be taken from well-separated points.02.Free Flowing Seed. For free-flowing seed in bags or bulk, a probe or trier is used. For small free-flowing seed in bags a probe or trier long enough to sample all portions of the bag is used.03.Non-Free Flowing Seed. Non-free-flowing seed, such as certain grass seed, uncleaned seed or screenings difficult to sample with a probe or trier, is sampled by thrusting the hand into the bulk and withdrawing representative portions. The hand is inserted in an open position and the fingers are held closely together while the hand is being inserted and the portion withdrawn.04.Composite Samples. Composite samples will be obtained to determine the quality of a lot of seed (i.e., percentages of pure seed, other crop seed, weed seed, inert matter and germination). Individual bag samples may be obtained to determine if the lot of seed is uniform.a. To determine if there is an obvious lack of uniformity of seed from which a composite sample is being obtained, each portion will be examined and the portions then combined to form a composite sample or samples.b. If the lot is found not to be uniform when obtaining a composite sample to determine its quality then additional individual bag samples are taken for the purpose of testing for uniformity.c. Such individual bag samples may also be taken for the purpose of testing for uniformity even though a composite sample has not previously been obtained. The identity of each individual bag sample must be maintained.05.Bulk. Bulk seed or screenings are sampled by inserting a long probe or thrusting the hand into the bulk, as circumstances require, in at least seven (7) uniformly distributed parts of the quantity being sampled. At least as many trierfuls or handfuls are taken as the minimum that would be required for the same quantity of seed or screenings in bags of a size customarily used for such seed or screenings.06.Bags. a. For lots of six (6) bags or less, each bag will be sampled with a total of at least five (5) trierfuls taken.b. For lots of more than six (6) bags, five (5) bags plus at least ten percent (10%) of the number of bags in the lots will be sampled. (Round off numbers with decimals to the nearest whole number, raising five tenths (.5) to the next whole number.) Regardless of the lot size it is not necessary that more than thirty (30) bags be sampled.c. Samples are drawn from unopened bags except under circumstances where the identity of the seed has been preserved.07.Packets. In sampling seed in packets, entire unopened packets are taken.08.Size of Sample.a. For composite sample to test for quality, the following are minimum weights for samples of seed to be submitted for analysis, test or examinationi. Two (2) ounces (approximately fifty five (55) grams) of grass seed not otherwise mentioned, white or alsike clover, or seeds not larger than these.ii. Five (5) ounces (approximately one hundred fifty (150) grams) of red or crimson clover, alfalfa, lespedezas, ryegrasses, bromegrasses, millet, flax, rape, or seeds of similar size.iii. One (1) pound of Sudangrass, sorghum, proso, hemp seed, or seeds of similar size.iv. Two (2) pounds (approximately one thousand (1,000) grams) of cereals, vetches, or seeds of similar or larger size.b. For individual bag samples to test for uniformity.i. The size of any individual bag sample to determine uniformity in a lot of seed is not less than the quantities set out in the "Rules and Regulations, under the Federal Seed Act" (53 Statute 1275) (Subsection 201.46).ii. If the sample drawn is larger than desired, it is thoroughly mixed before it is divided to the desired size.09.Forwarding and Receipt of Official Samples. Before being forwarded for analysis test or examination, the containers of official samples shall be properly sealed and identified with the containers of official samples initialed and dated and the sample weighed by the person who breaks the seals.Idaho Admin.
