# The Feeding Stuffs (Sampling and Analysis) Regulations 1999, Paragraph 1: Introduction


(a) In general a single method of analysis applies for the determination of the presence or quantity of a substance in feeding stuffs. Where two or more methods are prescribed the choice between them shall, except where otherwise indicated, be left to the agricultural analyst concerned; the method used must however be indicated in the certificate of analysis.
(b) the result given in the analysis report shall be the average value obtained from at least two independent determinations, carried out on separate portions of the sample, and of satisfactory repeatability.
(c) The result shall be expressed, in the manner laid down in the method of analysis, to an appropriate number of significant figures and shall be corrected, if necessary, to the moisture content of the final sample prior to preparation (see paragraph 3(d) below).
