Measurements uncertainty evaluation at determination yield of volative matter of solid mineral fuel

I.P. Zakharov, E.N. Shevchenko
Annotations languages:

The article discusses the relevance of the determination of yield of volatile matter of solid fuel,, an analytical determination of yield of volatile matter on analytical, working, dry and dry ash free state samples of fuel are analyzed, the circuit of performance measurement is resulted, the modeling equation is made, a budget of uncertainty is drawing up, expressions for calculation of the standard, combined and expanded uncertainty of measurement are received, recommendations on record of result of measurement are resulted.
Keywords: yield of volatile matter, uncertainty in measurements, coverage factor, uncertainty budget
