Petroleum products - Determination of boiling range distribution - Gas chromatography method (ISO 3924:2019)
This document specifies a method for the determination of the boiling range distribution of petroleum products. The method is applicable to petroleum products and fractions with a final boiling point of 538 °C or lower at atmospheric pressure as determined by this document. This document does not apply to gasoline samples or gasoline components. The method is limited to products having a boiling range greater than 55 °C and having a vapour pressure sufficiently low to permit sampling at ambient temperature.
The document describes two procedures.
a) Procedure A allows a larger selection of columns and analysis conditions, such as packed and capillary columns as well as a thermal conductivity detector in addition to the flame ionization detector. Analysis times range from 14 min to 60 min.
b) Procedure B is restricted to only three capillary columns and requires no sample dilution. The analysis time is reduced to about 8 min.
Both procedures have been successfully applied to samples containing fatty acid methyl esters (FAME) up to 20 % (volume fraction).
NOTE For the purposes of this document, the terms "% (mass fraction)" and "% (volume fraction)" are used to represent the mass fraction (µ), the volume fraction (φ) of a material.
Mineralölerzeugnisse - Bestimmung des Siedeverlaufs - Gaschromatographisches Verfahren (ISO 3924:2019)
Dieses Dokument legt ein Verfahren zur Bestimmung des Siedeverlaufs von Mineralölerzeugnissen fest. Das Verfahren ist anwendbar auf Mineralölerzeugnisse und Fraktionen mit einem nach diesem Dokument bestimmten atmosphärischen Siedeende von 538 °C oder darunter. Dieses Dokument gilt nicht für Ottokraftstoffproben oder Ottokraftstoffkomponenten. Das Verfahren ist beschränkt auf Erzeugnisse mit einem Siedebereich größer als 55 °C und mit einem Dampfdruck, der niedrig genug ist, um eine Probenahme bei Umgebungstemperatur zu ermöglichen.
Dieses Dokument beschreibt zwei Verfahren.
a) Verfahren A bietet eine größere Auswahl von Säulen und Analysenbedingungen, wie z. B. gepackte Säulen und Kapillarsäulen, sowie einen Wärmeleitfähigkeitsdetektor zusätzlich zum Flammen-ionisationsdetektor. Die Analysenzeit liegt zwischen 14 min und 60 min.
b) Verfahren B ist auf nur drei Kapillarsäulen begrenzt und erfordert keine Probenverdünnung. Die Analysenzeit wird auf etwa 8 min verringert.
Beide Verfahren wurden erfolgreich auf Proben mit einem Gehalt von Fettsäuremethylestern (FAME, en: fatty acid methyl ester) bis zu 20 % (Volumenanteil) angewendet
ANMERKUNG Für die Zwecke dieses Dokuments wird zur Angabe des Massenanteils (μ) einer Substanz der Ausdruck „% (Massenanteil)“ und für den Volumenanteil (φ) einer Substanz der Ausdruck „% (Volumenanteil)“ verwendet.
Produits pétroliers - Détermination de la répartition dans l'intervalle de distillation - Méthode par chromatographie en phase gazeuse (ISO 3924:2019)
Le présent document spécifie une méthode pour déterminer la répartition dans l'intervalle de distillation des produits pétroliers. La méthode est applicable aux produits pétroliers et aux fractions pétrolières dont le point final de distillation est inférieur ou égal à 538 °C à la pression atmosphérique quand il est mesuré en appliquant le présent document. Celui-ci ne s'applique pas au cas des essences ou composés à base d'essences. Le domaine d'application de la méthode est limité aux produits dont l'intervalle de distillation est supérieur à 55 °C et dont la pression de vapeur est suffisamment basse pour permettre un échantillonnage à la température ambiante.
Ce document présente deux modes opératoires:
a) Le mode opératoire A propose une sélection élargie de colonnes, telles que des colonnes capillaires ou remplies, et de conditions d'analyse avec aussi bien un catharomètre qu'un détecteur à ionisation de flamme (FID). Les temps d'analyse s'étendent sur un intervalle de 14 à 60 min.
b) Le mode opératoire B ne propose que trois colonnes capillaires et ne nécessite pas de dilution de l'échantillon. Le temps d'analyse se réduit à environ 8 min.
Ces deux modes opératoires ont été appliqués avec succès à des échantillons contenant des esters méthyliques d'acides gras (EMAG) jusqu'à des teneurs de 20% (en fraction volumique).
NOTE Pour les besoins du présent document, les termes "% fraction massique" et "% fraction volumique" sont utilisés pour désigner la fraction massique (µ) d'un produit et sa fraction volumique (φ).
Naftni proizvodi - Določevanje destilacijskega območja - Metoda plinske kromatografije (ISO 3924:2019)
Ta dokument določa metodo za določevanje destilacijskega območja naftnih proizvodov. Metoda se uporablja za naftne proizvode in frakcije z zgornjo točko vretja pri temperaturi 538 °C ali manj pri atmosferskem tlaku, kot je določeno v tem dokumentu. Ta dokument se ne uporablja za vzorce bencina ali sestavine bencina. Metoda je omejena na proizvode z destilacijskim območjem nad 55 °C in dovolj nizkim parnim tlakom, ki zagotavlja vzorčenje pri temperaturi okolja. Dokument opisuje dva postopka. a) Postopek A omogoča večjo izbiro kolon in analiznih pogojev, kot so nasute ali kapilarne kolone ter tudi detektor toplotne prevodnosti poleg plamensko ionizacijskega detektorja. Časi analize zajemajo od 14 min do 60 min. b) Postopek B je omejen na samo tri kapilarne kolone, redčenje vzorca pa ni potrebno. Čas analize je skrajšan na približno 8 min. Oba postopka se uspešno uporabljata pri vzorcih, ki vsebujejo do 20 % (prostorninski delež) metil estrov maščobnih kislin (FAME).
