The principle of the method consists in dividing of the contract sample (see ISO 542) by suitable means, if necessary after removal of impurities of large size, using one or other of the dividing instruments specified and taking care that the final analysis sample thruly represents the bulk of the contract for sample. A table gives the minimum mass of each analysis sample for 17 species of seed.
