4 Tests and sample sizes
4.1 Minimum mass of the laboratory sample
Sampling methods for spices and condiments are specified in ISO 948.
Considering the high cost of saffron, the mass of sample received in the laboratories for carrying out the tests is often limited. The minimum mass of the laboratory sample shall be 23 g (11,5 g x 2) for saffron filaments and cut filaments and 13,5 g (6,75 g x 2) for saffron powder in order to carry out the standard analyses in duplicate.
It is recommended that larger quantities of sample be placed at the disposal of the laboratories in case of dispute.
Since the mass of the test portion is low, it is advisable that it be taken from a homogenized sample.
4.2 Tests required and test sample sizes
See Table 1 for saffron in filaments, cut filaments and Table 2 for saffron in powder.
