3.2 Sampling Sampling shall be carried out in accordance with EN 196-7. Sample granular material in accordance with the procedures given in EN 932-1 for aggregates taking into account the need to minimize moisture and carbon dioxide absorption. The spot sample size shall be (8 ± 3) kg. The test sample prior to testing shall be kept in hermetically sealed containers. 3.3 Preparation of the sample Before carrying out tests, the mass of the sample shall be homogenized. Before carrying out chemical analyses, a representative sample of (50 ± 5) g shall be taken and be ground to a particle size of ≤ 0,1 mm. 3.4 Water The water used for reference tests and chemical analyses shall be distilled or deionised.

of particles
retained on 5000 µm sieves 4.1.2.1 Procedure From the hermetically sealed laboratory sample weigh 500 g ± 5 % and pass through a 5000 µm sieve, crushing any soft lumps with a spatula. Weigh the residue and examine any hard particles retained on the sieve. Repeat the procedure on a second sample. 4.1.2.2 Expression of
results Express the mass retained on the sieve as a percentage of the total sample. Take the mean of the two results and
record it in the test report. 4.1.3 Determination of particles retained on 200 µm and 100 µm sieves 4.1.3.1 Procedure Take approximately 200 g from the hermetically sealed sample and dry
it to constant mass1 at (40 ± 2) °C. Cool in a desiccator to room temperature. Weigh 50 g ± 5 % and transfer to the test sieve. Hold the sieve in one hand, slightly tilted, and shake it, allowing it to strike the other hand on each movement at a rate of approximately 125 times per minute, so that the plaster always spreads out evenly.
1 Constant mass is defined as two successive weighings 24h apart, differing by less than 0,1 %. SIST EN 13279-2:2004
