RULES AUD RBCJULATIONS 



Sampling 



(a) In order to secure a representative sample, equal portions shall 

 \>e taken from evenly distributed parts of the qiiantity of seed to be sampled. 

 Access shall be had to all parts of that quantity. 



(b) For free-flowing seed bags or bullc, a probe or trier shall be used. 

 For small free-flowing seed in bags, a probe or trier long enough to sample 

 all portions of the bag should be used. 



(c) Non-free-flowing seed, such as certain grass seed, uncleaned seed, 

 or screenings, difficult to sample with a probe or trier, shall be saiijpled 

 by thrusting the hand into the bulk and withdra^/ing representative portions . 



(d) The portions shall be combined into a composite sample or samples. 



(e) As the seed is sampled, each portion shall be examined, and when- 

 ever there appears to be a lack of iinifor:Tiity, additional sajnples shall be 

 taken to show such lack of uniformity as may exist . 



Bull-: seeds shall be sampled by inserting a long probe or thrusting the 

 hand into the bulk as circumstances require in several uniformly distributed 

 parts of the quantity being sampled. 



Bags, (l). In quantities of five bags or less, each bag shall be 

 sampled . 



(2) In quantities of more than five bags, at least every fifth bag but 

 not less than five bags shall be sampled. Samples shall be dra\m from un- 

 opened bags except under circumstances where the identity of the seed has 

 been preserved. 



In sampling packet seeds, entire unopened packets shall be tal:en. 



Size of sample. The follovring are minimum weights of samples of seed 

 to be submitted for analysis, test, or examination: 



(1) Tvro oxmces of grass seed not other^/ise mentioned, white or alsike

The New Hampshire seed laboratory ^-rilll be guided in making purity and 

 germination tests by the rules and regulations prescribed under the Federal 

 Seed Act. 



Tolerance 



OvTing to the natijiral variation between tests, the following tolerances 

 shall be allowed between the percentages found by analysis, test or examina-
