PART I DEFINITIONS
In this Schedule–
“sampled portion” means a quantity of a material constituting a unit and having characteristics presumed to be uniform;
“incremental sample” means a quantity taken from one point in the sampled portion;
“aggregate sample” means a aggregate of incremental samples taken from the same sampled portion;
“reduced sample” means a representative part of the aggregate sample obtained from the latter by a process of reduction;
“final sample” means a representative part of the reduced sample or, where no intermediate reduction is required, of the aggregate sample; and
“unit” has the same meaning as in the sampling Directive.

PART II INSTRUCTIONS FOR THE TAKING AND PREPARATION OF SAMPLES
1. In the case of feeding stuffs in packages or containers, except where section 68(2)(b) of the Act applies, only unopened packages or containers, which appear to the inspector proposing to take the sample to be the original packages or containers of the feeding stuff, shall be selected for the purpose of the sample.
2. The sample shall be taken and prepared as quickly as possible, having regard to the precautions necessary to ensure that it remains representative of the sampled portion. Instruments, surfaces and containers used in sampling shall be clean and dry.
3. No sample shall be drawn from any part of the sampled portion which appears to be damaged.
4. Where any appreciable portion of the feeding stuff appears to be mouldy, or is otherwise apparently unsuitable for feeding purposes, separate samples shall be drawn of the unsuitable portion and of the residue of the feeding stuff respectively. These shall be treated as separate sampled portions.
5. (1) An inspector who intends to take a sample in accordance with the provisions of section 76(1)(b) of the Act shall satisfy himself that the conditions in which the material concerned is stored are not such as might have caused undue deterioration thereof, and that it appears not to have been contaminated by any other material.
(2) The provisions of sub-paragraph (1) above shall not apply as respect any feeding stuff purchased for the purpose of resale in the course of trade.
6. The sampling apparatus shall consist of materials which cannot contaminate the feeding stuff to be sampled.
7. Subject to paragraph 8 below, in the absence of good reason to the contrary, the sampling apparatus for solid feeding stuffs shall be taken from among the following:
(a) a flat-bottomed shovel with vertical sides;
(b) a sampling spear with dimensions appropriate to the characteristics of the sampled portion in all respects, including dimensions of the container and particle size of the feeding stuff;
(c) mechanical apparatus which, if used for the purpose of sampling a feeding stuff being moved at the time the sample is taken, must be capable of taking samples right across the flow of the product;
(d) apparatus designed to divide the sample into approximately equal parts for taking incremental samples, and for the preparation of reduced and final samples.
8. A sampling spear shall not be used if the material is in a package or container containing not more than 50 kg and, prior to the taking of a sample, the manufacturer objects to such use on the ground that the material is unsuitable.
9. The sample shall be taken, prepared and packaged in accordance with the requirements specified, in the Annex to the Sampling Directive–
(a) in paragraphs 5A and 5B under the heading “QUANTITATIVE REQUIREMENTS” (as set out in section A of the Table to this Part); and
(b) in paragraphs 6.2 to 6.4 under the heading “INSTRUCTION FOR TAKING, PREPARING AND PACKAGING THE SAMPLES” (as set out in Section B of the Table to this Part).
10. Any sample taken in accordance with the preceding paragraphs of this Schedule shall be considered as representative of the sampled portion.

SCHEDULE 2 METHODS OF ANALYSIS
Regulation 6

PART I GENERAL PROVISIONS

Introduction
1. (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).

Reagents and Apparatus
2. (a) Unless otherwise specified in the method of analysis concerned, all reagents must be analytically pure. The purity of the reagents, especially when determining trace elements, must be checked by a blank test. Depending upon the results obtained, further purification of the reagents may be required.
(b) Where any operation involves preparation of solutions, dilution, rinsing or washing, as part of a method of analysis, water must be used unless the specification of the method indicates otherwise.
(c) Water should, in the absence of good reason to the contrary, be demineralized or distilled. Where indicated in the method of analysis concerned it must be subjected to special purification procedures.
(d) All instruments or apparatus used must be clean, especially when very small amounts of substances have to be determined.

Preparation of the sample for analysis
3. (a) Samples must be prepared in such a way that the amounts weighed out, as provided for in the methods of analysis, are homogeneous and representative of the final sample.
(b) All the necessary operations must be performed in such a way as to avoid, as far as possible, any change in, or contamination of, the sample. Grinding, mixing and sieving should be carried out as quickly as possible, with minimal exposure of the sample to air and light. Overgrinding is to be avoided. Mills and grinders likely to heat the sample appreciably should not be used. Nevertheless, where some loss or gain of moisture is unavoidable, allowance should be made for such changes (see sub-paragraph (d) below). Manual grinding is recommended for feeding stuffs which are particularly sensitive to heat. Care should also be taken to ensure that the apparatus itself is not a source of contamination by trace elements.
(c) If the final sample as received consists of unopened packages or containers then, immediately prior to the preparation of the sample for analysis, all the contents shall be thoroughly mixed together.
(d) If the sample is appreciably moist, or if for any reason the preparation cannot be carried out without significant changes in the moisture content of the sample, determine the moisture content before and after preparation, using the method specified in columns 2 and 3 of Annex I to Part II of this Schedule, appearing opposite to the reference to “Moisture” in column 1 of that Annex.
(e) When a microscopial examination for the presence of undesirable substances is required then, in the absence of good reason to the contrary–
(i) the sample should be crushed and ground only to such an extent as facilitates the examination, and
(ii) grinding to pass 1 mm should not be used where it could lead to difficulties in identifying the undesirable substances listed in Schedule 5 of the Feeding Stuffs Regulations 1995.
S.I. 1995/1412; the relevant amendments are in S.I. 1996/1260, 1998/2072 and 1999/1528.

(f) Procedure
Mix the sample thoroughly either mechanically or manually. Divide the sample into two equal portions (the quartering method should be used where applicable). Preliminary crushing and/or grinding may be necessary, if the sample is in a coarse condition, to facilitate division. Keep one of the portions in a suitable container, i.e. non-corrodible, clean and dry and fitted with an air-tight stopper, and prepare the other portion or a representative part of it, of at least 100 g, as indicated below.
(i) Feeding stuffs which can be ground as such
Unless otherwise specified in the method of analysis concerned, sieve the whole sample through a sieve having apertures of 1 mm square, in accordance with recommendation ISO R565, after grinding, if necessary.
(1) Test sieves conforming to British Standard 410:1976 are suitable.
(2) Where an analysis for copper has to be carried out, a stainless steel sieve should be used.
Mix the sieved sample and collect it in a suitable container, i.e. non-corrodible, clean and dry and fitted with an air-tight stopper. Mix again, immediately before weighing out the amounts for analysis.
(ii) Feeding stuffs which can be ground only after drying
Unless otherwise specified in the method of analysis concerned, dry the sample to reduce its moisture content to a level of 8–12%, in accordance with the preliminary drying procedure specified in point 4.3 of the method referred to in sub-paragraph (d) above, until grinding enables the sample to be passed wholly through a sieve having apertures of 1 mm square. Then proceed as indicated in sub-paragraph (f)(i) above.
(iii) Liquid or semi-liquid feeding stuffs
Collect the sample in a suitable container, i.e. non-corrodible, clean and dry and fitted with an air-tight stopper. Mix thoroughly immediately before weighing out the amount for analysis.
(iv) Other feeding stuffs
A sample which cannot be prepared according to any of the above procedures should be treated by any other procedure which ensures that the amounts weighted out for analysis are homogeneous and representative of the final sample.

(g) Storage of samples
Samples must be stored at such a temperature as will cause no compositional changes. A sample intended for the analysis of vitamins, or substances which are particularly sensitive to light, should be placed in a brown glass container.

PART II METHODS OF ANALYSIS
The methods of analysis for the purposes of this Schedule are–
(a) Community methods of analysis, as specified in Annex I to this Part of this Schedule;
(b) the method for determining uric acid, as specified in Annex II to this Part of this Schedule; and
(c) the method for determining isobutylidenediurea, as specified in Annex III to this Part of this Schedule.
