Time, according to GB/T 601, GB/T 602 and GB/T 603 requirements.
4 sampling
4.1 Laboratory samples
According to the provisions of GB/T 6679 obtained.
4.2 samples
The laboratory samples were mixed evenly and about 40 g was fractionated by a quartile. The pellets were crushed and graded in a porcelain mortar.
The samples were passed through a 150 μm test sieve (according to the R40/3 series in GB/T 6003.1), placed in a weighing flask, dried at 105 ° C
To constant volume, remove into the dryer, cooling to room temperature, spare.
