where individual samples are analysed, one sample showing a single defect out of five to 10 samples or two samples each showing a single defect out of 11 to 15 samples may be allowed. Where a sample shows a defect, two new samples must be taken from either side of the sample showing the defect and checked for the parameter in question. Where neither sample meets the specification, the quantity of butter between the original two samples on either side of the sample showing the defect must be rejected from the quantity offered.
Quantity to be rejected where the new sample shows a defect:
where composite samples are analysed and found to show defects in respect of one parameter, the quantity represented by the composite sample concerned is to be rejected from the quantity offered. The quantity represented by one composite sample may be determined by subdividing the quantity before samples are taken randomly from each part thereof;
