Abstract
On the basis of the principles in State Standard GOST R ISO 21748, formulas are derived for the expanded uncertainty in standard methods of measurements of eleven coal parameters. Values of the uncertainty are calculated. A form of representation of the measurement results is proposed for use in the test protocols of laboratories accredited on the basis of State Standard GOST ISO 17025.
