Section 7

When it is intended to submit any sample for analysis, the officer purchasing or otherwise procuring it shall, before or forthwith after procuring it, inform the seller or his agent selling the article or the person having charge of the article that he intends to have the sample analysed by an analyst.

Such officer shall thereupon divide the sample into 3 parts, and shall mark and seal or fasten up in such manner as its nature permits each such part, and shall offer one of those parts to the seller or his agent or the person having charge of the article.

Such officer shall subsequently deliver either personally or by registered letter another of those parts to an analyst, and shall retain the third of those parts.

Where a sample consists of a substance contained in unopened containers or packages and the division into parts of the substance contained in those containers or packages is not reasonably practicable or might affect the composition or impede the proper analysis of the contents, subsection (2) shall be deemed to be complied with if the officer procuring the sample divides the containers or packages into the requisite number of lots and deals with each lot as if it were a part in the manner provided by this section; and references in this Act to a part of a sample shall be construed accordingly.
