Analysis method
4.1 Determination of total mass fraction of water .
4.1.1 Position
Total mass fraction of water is total water contents of definite qaulity during sampling. At 102-105 lost quality which is 1/100 part of the previous quality is a total mass fraction of water.
4.1.2 Devices
а) Drier;
b) SUrfacial layer: Diameter 190mm;
с) Balance: accuracy of 0.1 gr
4.1.3 The results of determination of mass fraction of charcoal is to be calculated by formula : W=(1-m/m) x 100
4.3 Determination of mass fraction of coal grains of no less than 100 mm
4.3.1 Position
When taking samples of a definite weight, sieve with the mesh of 10x10mm is used for sorting, the number of sorted grains is 1/100 of quality of test samples..
4.3.2 Devices
а) Sieve: GF3W10.0 x 2.50
b) Mortar and pestle
с) Balance with accuracy up to 0,1 kg
4.3.3 Analysis procedure
Test samples (10 kg) are taken (accuracy 0,1 kg). The samples are placed on the Sieve, sifted out by turns and weight the mass .
4.3.4 The result of determination of coal grains of no less than 10 kg is to be calculated by formula:
М = mt/mс Х 100,
where М ----- grain contents of no less than 10mm , %
mt ----- Fraction of grain of no less than 10 mm, kg
mс ---- Fraction of test sifted grains , kg.
4.4 Determination of coal pieces and sand contents
4.4.1 Coal pieces and sand contents are to be calculated by formula : H=m3/mo, Where Н – is coal and sand contents, %; m3 – coal and sand fraction, kg; mo – tested (sifted) fraction , kg.
 
5. Analysis methods

5.1 Coal grade, quality index of each coal consignment should be similar. At the same time, before delivery any quantity of coal is to be checked by manufacturing companies or quality check organizations, who make standard technical report .
5.2 Sampling analysis

5.2.1During bulk transportation, from the beginning of loading and unloading, middle and last stages are divided by 3 in accordance with equal sampling in amount of 3-5% of total quantity. After convergence general samples are determined.

5.2.2 All samples are taken in duplicate, the fraction of each sample is no less than 100 kg. First copy of all samples is used for tests, if the test result do not correspond the standard requirements, than the second copy is used for repeated test.

5.2.3 During the test of all samples are taken regularly, then all samples are divided into four parts. The first part is used to analyze samples, the remaining part are use to determine granularity. Coal that serves for analysis of samples should be immediately placed in three clean and dry glass bottles.The legend on each bottle include name and number of samples, manufacturing company, type of coal, number of consignment, date of sampling, name of the person who took the samples.
Then one bottle is used to determnine mass fraction of water, the second bottle is taken for analysis, the third one is to be stored during two months for the secondary analysis.

5.3 Rules and methods

5.3.1 If the analysis results do not meet the requirements of p 3.2, then it is necessary to used parallel samples for the secondary analysis. If the results of the secondary analysis do not meet the requirements of pp. 3.2, then all the consignment doesn't meet standard requirments.

5.3.2The buying company has right to test all the purchased coal using these standard rules and methods.

5.3.3. In case of disagreement the conflicting parties are entitled to apply for arbitration. The arbitration is to be conducted in accordance with rules and methods of the present Standard .
