Petroleum products - Determination of aromatic hydrocarbon types in middle distillates - High performance liquid chromatography method with refractive index detection

This European Standard specifies a test method for the determination of the content of mono-aromatic, di-aromatic and tri+-aromatic hydrocarbons in diesel fuels that may contain fatty acid methyl esters (FAME) up to 30 % (V/V) and petroleum distillates in the boiling range from 150 °C to 400 °C. The polycyclic aromatic hydrocarbons content is calculated from the sum of di-aromatic and tri+-aromatic hydrocarbons and the total content of aromatic compounds is calculated from the sum of the individual aromatic hydrocarbon types.
Compounds containing sulfur, nitrogen and oxygen can interfere in the determination; mono-alkenes do not interfere, but conjugated di-alkenes and poly-alkenes, if present, may do so.
The precision statement of the test method has been established for diesel fuels with and without FAME blending components, with a mono-aromatic content in the range from 6 % (m/m) to 30 % (m/m), a di-aromatic content from 1 % (m/m) to 10 % (m/m), a tri+-aromatic content from 0 % (m/m) to 2 % (m/m), a polycyclic aromatic content from 1 % (m/m) to 12 % (m/m), and a total aromatic content from 7 % (m/m) to 42 % (m/m).
NOTE 1   For the purpose of this European Standard, the terms "% (m/m)" and "% (V/V)" are used to represent the mass fraction and the volume fraction of a material respectively.
NOTE 2   By convention, the aromatic hydrocarbon types are defined on the basis of their elution characteristics from the specified liquid chromatography column relative to model aromatic compounds. Their quantification is performed using an external calibration with a single aromatic compound for each of them, which may or may not be representative of the aromatics present in the sample. Alternative techniques and test methods may classify and quantify individual aromatic hydrocarbon types differently.
WARNING - The use of this Standard can involve hazardous materials, operations and equipment. This Standard does not purport to address all of the safety problems associated with its use. It is the responsibility of users of this standard to take appropriate measures to ensure the safety and health of personnel prior to application of the standard, and fulfil statutory and regulatory requirements for this purpose.

Naftni proizvodi - Določevanje aromatskih ogljikovodikov v srednjih destilatih - Metoda tekočinske kromatografije visoke ločljivosti z detekcijo lomnega količnika

Ta evropski standard opredeljuje preskusno metodo za določanje vsebnosti monoaromatskih, diaromatskih in tri+-aromatskih ogljikovodikov v dizelskih gorivih, ki lahko vsebujejo do 30-odstotne (V/V) metilne estre maščobnih kislin (FAME) in naftne destilate z območjem vrelišča od 150 °C do 400 °C. Vsebnost policikličnih aromatskih ogljikovodikov je izračunana na podlagi vsote diaromatskih in tri+-aromatskih ogljikovodikov, skupna vsebnost aromatskih spojin pa je izračunana na podlagi vsote posameznih
vrst aromatskih ogljikovodikov.
Spojine z vsebnostjo žvepla, dušika in kisika lahko povzročajo motnje pri določanju; monoalkeni
ne povzročajo motenj, vendar jih konjugirani dialkeni in polialkeni lahko povzročajo, če so prisotni.
Izjava o natančnosti preskusne metode je bila določena za dizelska goriva s komponentami za mešanje z metilnimi estri maščobnih kislin in brez njih,
ki imajo 6-odstotno (m/m) do 30-odstotno (m/m) vsebnost monoaromatskih spojin, 1-odstotno (m/m) do 10-odstotno (m/m) vsebnost diaromatskih spojin, 0-odstotno (m/m) do
2-odstotno (m/m) vsebnost tri+-aromatskih spojin, 1-odstotno (m/m) do 12-odstotno (m/m) vsebnost policikličnih aromatskih spojin in 7-odstotno (m/m) do 42-odstotno (m/m) skupno vsebnost aromatskih spojin.
OPOMBA 1: V tem evropskem standardu sta uporabljeni oznaki % (m/m) in % (V/V), ki predstavljata masni delež oziroma prostornino materiala.
OPOMBA 2: Po dogovoru so vrste aromatskih ogljikovodikov opredeljene na podlagi njihovih elucijskih lastnosti določene kolone tekočinske kromatografije v primerjavi z modelnimi aromatskimi spojinami. Njihova kvantifikacija se izvede z uporabo zunanjega umerjanja z enojno aromatsko spojino za posamezno vrsto aromatskih ogljikovodikov, ki je lahko reprezentativna za aromatske spojine iz vzorca ali pa tudi ne. Druge tehnike in preskusne metode lahko drugače razvrstijo in kvantificirajo posamezne vrste aromatskih ogljikovodikov.
OPOZORILO: Pri uporabi tega standarda so lahko prisotni nevarni materiali, postopki in oprema. Ta standard ne obravnava vseh varnostnih težav, ki se nanašajo na njegovo uporabo. Za sprejetje ustreznih ukrepov za zagotavljanje varnosti in zdravja osebja pred uporabo standarda ter izpolnjevanje zakonskih in regulativnih zahtev za ta namen so odgovorni uporabniki tega standarda.
