STANDARD SAMPLES FOR METROLOGICAL SUPPORT OF TESTS FOR MEASURING CHEMICAL STABILITY OF JET ENGINE FUELS (OPTIONS) Russian patent published in 2021 - IPC G01N33/22 G01N31/00 G01N25/00 G01N1/00 

FIELD: metrology.

SUBSTANCE: invention describes standard samples for metrological support of tests for measuring the chemical stability of jet engine fuels containing chemically pure hydrocarbons, characterized by the fact that they contain decalin, 1-decene and n-undecane at the following ratio of components, wt. %: decalin 48-67, 1-decene 2-18 and n-undecane - the rest. The invention also describes standard samples for metrological support of tests for measuring the chemical stability of jet engine fuels containing chemically pure hydrocarbons, characterized by the fact that they contain n-undecane, decalin and 1-methylnaphthalene at the following ratio of components, wt. %: decalin 12-23, 1-methylnaphthalene 2-5, n-undecane - the rest.

EFFECT: increase in the reliability of the results of measuring the chemical stability of jet engine fuels and a reduction in the duration of the certification process of the installation where their chemical stability is determined, and an expansion of the range of standard samples for metrological support of tests for measuring the chemical stability of various fuels.
