The average sample is obtained by quartering. Form the pooled sample, adequately mixed, into an even and square –shaped heap, and divide it diagonally into four equal parts .Take two diagonally opposite parts and mix carefully. Repeat the process as necessary until the required quantity , to within 10 per cent, obtained. Any remaining material should be returned to the batch.
Using the same quartering procedure, divide the average sample into four final samples, taking care that each portion is representative of the bulk material
Sampling of material in retail packages
Form each wholesale container (boxes, cartons ,etc.) selected for sampling take at random two consumer packages. Form small batches ( 1 to 5 boxes ), take ten consumer packages. Prepare the pooled sample by mixing the contents of the selected consumer packages and proceed as described above to obtain the final sample.
