Petroleum products - Determination of sulfur content of automotive fuels - Ultraviolet fluorescence method (ISO 20846:2019)
This document specifies an ultraviolet (UV) fluorescence test method for the determination of the sulfur content of the following products:
— having sulfur contents in the range 3 mg/kg to 500 mg/kg,
— motor gasolines containing up to 3,7 % (m/m) oxygen [including those blended with ethanol up to about 10 % (V/V)],
— diesel fuels, including those containing up to about 30 % (V/V) fatty acid methyl ester (FAME),
— having sulfur contents in the range of 3 mg/kg to 45 mg/kg,
— synthetic fuels, such as hydrotreated vegetable oil (HVO) and gas to liquid (GTL).
Other products can be analysed and other sulfur contents can be determined according to this test method, however, no precision data for products other than automotive fuels and for results outside the specified range have been established for this document. Halogens interfere with this detection technique at concentrations above approximately 3 500 mg/kg.
NOTE 1 Some process catalysts used in petroleum and chemical refining can be poisoned when trace amounts of sulfur-bearing materials are contained in the feedstocks.
NOTE 2 This test method can be used to determine sulfur in process feeds and can also be used to control sulfur in effluents.
NOTE 3 For the purposes of this document, "% (m/m)" and "% (V/V)" are used to represent the mass fraction, w, and the volume fraction, φ, of a material respectively.
NOTE 4 Sulfate species in ethanol do not have the same conversion factor of organic sulfur in ethanol. Nevertheless, sulfates have a conversion factor close to that of organic sulfur.
NOTE 5 Nitrogen interference can occur, see 6.5 for further guidance.
Mineralölerzeugnisse - Bestimmung des Schwefelgehaltes von Kraftstoffen - Ultraviolettfluoreszenz-Verfahren (ISO 20846:2019)
Dieses Dokument enthält Festlegungen an ein Ultraviolettfluoreszenz Verfahren zur Bestimmung des Schwefelgehaltes von folgenden Erzeugnissen:
— mit einem Schwefelgehalt im Bereich von 3 mg/kg bis 500 mg/kg;
— Ottokraftstoffe, die bis 3,7 % (m/m) Sauerstoff (einschließlich solcher mit einem Gehalt bis 10 % (V/V) Ethanol) enthalten;
— Dieselkraftstoffe, die bis 30 % (V/V) Fettsäuremethylester (FAME) enthalten;
— mit einem Schwefelgehalt im Bereich von 3 mg/kg bis 45 mg/kg;
— synthetische Kraftstoffe, z. B. hydrogeniertem Pflanzenöl (HVO) und Gas to Liquid (GTL).
Andere Erzeugnisse und andere Schwefelgehalte können mit diesem Verfahren untersucht werden, jedoch wurden die in diesem Dokument angegebenen Präzisionsangaben nur für Kraftstoffe für Kraftfahrzeuge für den angegebenen Bereich ermittelt. Halogene stören die Bestimmung bei Konzentrationen oberhalb von etwa 3 500 mg/kg.
ANMERKUNG 1 Einige der in Raffinerieprozessen der Erdöl und chemischen Industrie verwendeten Katalysatoren können vergiftet werden, wenn in den Einsatzprodukten Spuren von schwefelhaltigen Substanzen enthalten sind.
ANMERKUNG 2 Dieses Prüfverfahren kann zur Bestimmung von Schwefel in Raffinerie Zwischenprodukten und auch zur Kontrolle von Schwefel in Endprodukten verwendet werden.
ANMERKUNG 3 Für die Zwecke dieses Dokuments wird zur Angabe des Massenanteils, w, einer Substanz „% (m/m)“ und für den Volumenanteil, φ, einer Substanz der Ausdruck „% (V/V)“ verwendet.
ANMERKUNG 4 Sulfatspuren in Ethanol haben zwar nicht denselben Umrechnungsfaktor wie organischer Schwefel in Ethanol, jedoch ist er diesem sehr ähnlich.
ANMERKUNG 5 Störungen durch Stickstoff können auftreten; siehe 6.5 für weitere Einzelheiten.
Produits pétroliers - Détermination de la teneur en soufre des carburants pour automobiles - Méthode par fluorescence ultraviolette (ISO 20846:2019)
Le présent document spécifie une méthode par fluorescence ultra-violette (FUV) pour le dosage du soufre dans les produits suivants:
— ceux dont la teneur en soufre est comprise dans l'intervalle de 3 à 500 mg/kg:
— les essences automobiles contenant jusqu'à 3,7 % (m/m) en oxygène [les mélanges avec de l'éthanol jusqu'à environ 10 % (V/V) inclus],
— les carburants diesel, dont ceux contenant jusqu'à 30 % (V/V) d'esters méthyliques d'acides gras.
— ceux dont la teneur en soufre est comprise dans l'intervalle de 3 à 45 mg/kg:
— les carburants synthétiques, tels que les huiles végétales hydrogénées (HVO) et les carburants liquides produits à partir de gaz («gas to liquid», GTL).
D'autres produits peuvent être analysés et d'autres teneurs en soufre peuvent être déterminées suivant cette méthode, cependant, il n'a pas été établi de données de fidélité pour des produits autres que les carburants pour automobiles et pour des résultats en dehors de la gamme spécifiée pour le présent document. Les halogènes, à des concentrations supérieures à environ 3 500 mg/kg, interfèrent.
NOTE 1 Certains catalyseurs utilisés dans le raffinage chimique et pétrolier peuvent être pollués lorsque des composés soufrés sont présents en trace dans les charges.
NOTE 2 Cette méthode peut être utilisée pour déterminer la teneur en soufre des charges et peut aussi être utilisée pour contrôler la teneur en soufre des effluents.
NOTE 3 Pour les besoins du présent document, «% (m/m)» et «% (V/V)» sont utilisés pour désigner respectivement la fraction massique, w, et la fraction volumique, φ, d'un produit.
NOTE 4 Le facteur de conversion des sulfates dans l'éthanol n'est pas le même que celui des composés organiques sulfurés dans l'éthanol. Ils sont cependant proches.
NOTE 5 Une interférence avec l'azote peut avoir lieu, voir 6.5 pour plus de précisions.
Naftni proizvodi - Določevanje žvepla v gorivih za motorna vozila - Ultravijolična fluorescenčna metoda (ISO 20846:2019)
Ta dokument določa ultravijolično fluorescenčno preskusno metodo za določevanje žvepla v naslednjih proizvodih: – proizvodih z vsebnostjo žvepla od 3 do 500 mg/kg; – bencinu za motorna vozila, ki vsebuje do 3,7 % (m/m) kisika (vključno z mešanicami z do 10-odstotno (V/V) vsebnostjo etanola); – dizelskih gorivih, vključno z gorivi, ki vsebujejo do 30 % (V/V) metilnih estrov maščobnih kislin (FAME); – proizvodih z vsebnostjo žvepla od 3 do 45 mg/kg; – sintetičnih gorivih, kot so z vodikom obdelano rastlinsko olje (HVO) in produkti pretvorbe plina v tekočino (GTL). To preskusno metodo je mogoče uporabiti za analizo drugih proizvodov in vsebnosti žvepla v drugih proizvodih, vendar za ta dokument niso bili določeni podatki o natančnosti za proizvode, ki niso goriva za motorna vozila, in za rezultate zunaj določenega obsega. Halogeni pri koncentracijah nad 3500 mg/kg vplivajo na to tehniko zaznavanja.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing Documents is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates
closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical
standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www .iso

This document was prepared by Technical Committee ISO/TC 28, Petroleum and related products, fuels
and lubricants from natural or synthetic sources.
This third edition cancels and replaces the second edition (ISO 20846:2011), which has been technically
revised. The main change compared to the previous edition is the extension of the Scope to include
hydrotreated vegetable oil (HVO) and the synthetic fuel “gas to liquid” (GTL).
