Measurements uncertainty evaluation at determination ash in solid mineral fuel

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

The relevance of the definition of solid fuel ash is considered, an analytical determination of ash content on analytical, working and dry 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: Ash content, uncertainty of measurements, factor of scope, uncertainty budget
