The AASCO Handbook on Seed Sampling presents methods, guidelines and equipment for both regulatory and industry applications to uniformly obtain representative seed samples for laboratory testing.  It also provides sampling procedures for the USA Accredited Seed Sampling Program (ASSP) for national and international certification and may be recognized by the Canadian Food Inspection Agency (CFIA).  The intent is to provide a broadly adaptable format to all seed sampling situations so that the resultant laboratory analyses accurately reflect the quality of the seed lot and prevent potential trade barriers from variability in sampling.
