Sampling -- Methods used in the sampling,
inspecting, testing, analyzing and examining seed for
certification. (1) The terms used in seed testing and the
methods of sampling, inspecting, analyzing, testing and examining
seed for certification are those adopted by the AOSA as shown in
WAC 16-301-010.
(2) The entire lot of seed must be cleaned and in condition
for sale at the time of sampling. Except for ryegrass which may
be sampled under the early sampling program as allowed in WAC 16-302-091.
(3) The department shall obtain a representative sample for
laboratory analysis of each lot of seed for certification. The
sample shall be taken in accordance with official sampling
procedures. Official sampling procedures are as follows:
Seed in bags.
(a) When more than one core is drawn from a bag, follow
different paths. When more than one handful is taken from a bag,
take them from well-separated points.
(b) For lots of one to six bags, sample each bag and take a
total of at least five cores or handfuls.
(c) For lots of more than six bags, sample five bags plus at
least 10% of the number of bags in the lot. Round numbers with
decimals to the nearest whole number. Regardless of the lot
size, it is not necessary to sample more than thirty bags.

(4) Bulk seed. To obtain a composite sample, take at least
as many cores or handfuls as if the same quantity of seed were in
bags of an ordinary size. Take the cores or handfuls from well
distributed points throughout the bulk.
(5) Seed in small containers. Seed in small containers
shall be sampled by taking the entire unopened container in
sufficient number to supply a minimum size sample for testing.
The contents of a single container or the combined contents of
multiple containers of the same lot shall be considered
representative of the entire lot of seed sampled.
(6) A mechanical sampling device installed in a conditioning
plant approved by the department under WAC 16-302-125 may be used
in lieu of the sampling procedures above.
(7) If it is necessary for a sample to be taken by the
department, a sampling fee will be charged under provisions of
chapter 16-303 WAC.
