An inspector who takes a sample must ensure that:
(a) the container of the sample is marked so that the sample is clearly identifiable, but in a way that prevents a person testing the sample from identifying the source of the sample; and
(b) the container cannot be opened, or the identification of the sample removed, without breaking the seal; and
(c) the sample is packed, stored and transported in a way that ensures:
(i) the integrity of the sample is preserved; and
(ii) testing of the sample produces the same results as would have been obtained if the sample had been tested immediately after it was taken.
