1.1. General U.K.

The mass of the sample presented to the laboratory for analysis shall be at least 200 grams.

1.2. Preparation of the sample for analysis in the laboratory U.K.
1.2.1.Thoroughly mix and break down any lumps, etc., in the laboratory sample by repeatedly shaking and inverting the container (if necessary, after having transferred all of the laboratory sample to an air-tight container of sufficient capacity (twice Volume of sample) to allow this operation to be carried out).U.K.
1.2.2.Transfer a representative portion of the sample, i.e. about 50 grams of the thoroughly mixed laboratory sample (1.2.1) to the test sieve (3.3).U.K.
1.2.3.If the 50 gram portion completely or almost completely passes (at least 95 % by weight) through the sieve (3.3), use for the determination the sample as prepared in 1.2.1.U.K.
1.2.4.Otherwise, grind the 50 gram portion, using the grinding device (3.4), until it satisfies the sieving criterion (1.2.3). Immediately transfer all the sieved sample to an air-tight container of sufficient capacity (twice volume of sample) and mix thoroughly by repeated shaking and inverting. During these operations, take precautions to avoid any change in the moisture content of the product.U.K.
1.2.5.After the test sample has been prepared, any determination should be proceeded with as soon as possible.U.K.
1.3. Containers U.K.

The sample shall always be kept in an air-tight and moisture-tight container.


2.1. Water U.K.
2.1.1.Wherever mention is made to water for solution, dilution or washing purposes, distilled water, or de-mineralized water of at least equivalent purity, shall be used.U.K.
2.1.2.Wherever reference is made to ‘solution’ or ‘dilution’ without further indication, ‘solution in water’ or ‘dilution with water’ is meant.U.K.
2.2. Chemicals U.K.

All chemicals used shall be of recognized analytical reagent quality except where otherwise specified.


3.1. Lists of equipment U.K.

The lists of equipment contain only those items with a specialized use and items to a particular specification.

3.2. Analytical balance U.K.

Analytical balance means a balance capable of weighing to at least 0,1 mg.

3.3. Test sieve U.K.

The test ieves to be used are to be fitted with a lid, to be of diameter 200 mm, to be constructed of wire cloth with a nominal aperture size of 500 urn. The aperture tolerances and wire diameters to be permitted are as given in ISO 3310/1. (Test sieves — Technical requirements and testing — Part 1: Metal wire cloth. ISO 3310/1 — 1975).

The sieves are to be fitted with a receiver.

3.4. Grinding device U.K.

For grinding the laboratory sample if necessary (see 1.2.4), without development of undue heat and without loss or absorption of moisture, a hammer mill shall not be used.


4.1. Results U.K.

The result stated in the analytical report is to be the mean value obtained from two determinations which satisfy the repeatability criterion for that method.

4.2. Calculation of percentage U.K.

Except where otherwise specified, the result shall be calculated as a percentage by mass of the sample.


The test report shall identify the method of analysis used as well as the results obtained. In addition, it shall mention all details of procedure not specified in the method of analysis or which are optional, as well as any circumstances that may have influenced the results obtained. The test report shall give all the information necessary for the complete identification of the sample.
