Petroleum products - Gum content of fuels - Jet evaporation method - Amendment 1: Purity requirement for n-heptane (ISO 6246:2017/Amd 1:2019)

This document specifies a method for determining the existent gum content of aviation fuels and the
gum content of motor gasoline or other volatile distillates. It includes the determination of products
containing ethanol (up to a volume fraction of 85 %) and ether-type oxygenates and deposit control
additives.
For determination of gum content in automotive ethanol (E85) fuel, no precision data is available
(see 14.1).
For non-aviation fuels, a procedure for the determination of the heptane-insoluble portion of the residue
is also described.
CAUTION — This method is not intended for the testing of gasoline components, particularly
those with a high percentage of low-boiling unsaturated compounds, as they can cause
explosions during evaporation.

Naftni proizvodi - Vsebnost smolnega ostanka v gorivih - Metoda s prepihavanjem - Dopolnilo A1: Zahteva glede čistosti n-heptana (ISO 6246:2017/Amd 1:2019)

Ta dokument določa metodo za določevanje obstoječe vsebnosti smolnega ostanka v letalskih gorivih in vsebnosti smolnega ostanka v bencinu za motorna vozila ali drugih hlapnih destilatih. Vključuje določevanje izdelkov, ki vsebujejo etanol (s prostorninskim deležem do vključno 85 %) ter etrske kisikove spojine in aditive za nadzor ostankov.
Za določevanje vsebnosti smolnega ostanka v etanolu (E85), ki se uporablja kot motorno gorivo, ni na voljo podatkov o natančnosti (glej točko 14.1).
Za goriva, ki se ne uporabljajo v letalstvu, je opisan tudi postopek za določevanje dela ostanka, ki ni topen v heptanu.
POZOR – ta metoda ni namenjena za preskušanje komponent bencina, zlasti tistih z visokim deležem nenasičenih spojin z nizkim vreliščem, ker lahko med izhlapevanjem povzročijo eksplozije.
