Liquid petroleum products - Vapour pressure - Part 3: Determination of vapour pressure and calculated dry vapour pressure equivalent (DVPE) (Triple expansion method)
This document specifies a method for the determination of the vapour pressure, exerted in vacuo, by volatile, low viscosity petroleum products, components, ethanol blends up to 85 % (V/V), and feedstocks using a variable volume chamber. A dry vapour pressure equivalent (DVPE) is calculated from the vapour pressure.
The conditions used in the test described in this document are a vapour-to-liquid ratio of 4:1 and a test temperature of 37,8 °C.
The equipment is not wetted with water during the test, and the method described is therefore suitable for testing samples with or without oxygenates; no account is taken of dissolved water in the sample.
This procedure calculates the partial pressure of the air dissolved in the test portion during the triple expansion process. It is suitable for samples with a DVPE between 15,7 kPa and 97,6 kPa; vapour pressures outside this range can be measured but the precision has not been determined.
This document is applicable to fuels containing oxygenated compounds up to the limits stated in the relevant Council Directive 85/536/EEC [6], and for ethanol-fuel blends up to 85 % (V/V) ethanol.
NOTE For the purposes of this document, the terms "% (m/m)" and "% (V/V)" are used to represent the mass and volume fractions respectively.
WARNING - The use of this document can involve hazardous materials, operations and equipment. This document does not purport to address all of the safety problems associated with its use. It is the responsibility of users of this document to take appropriate measures to ensure the safety and health of personnel prior to application of the standard, and to determine the applicability of any further restrictions for this purpose.
Flüssige Mineralölerzeugnisse - Dampfdruck - Teil 3: Bestimmung des Dampfdruckes und des berechneten dem trockenen Dampfdruck entsprechenden Druckes (DVPE) (Dreifach-Expansionsmethode)
Dieses Dokument legt unter Verwendung einer Kammer mit veränderlichem Volumen ein Verfahren zur Bestimmung des Dampfdrucks fest, der in negativem Überdruck von flüchtigen, niedrigviskosen Mineralölerzeugnissen, Komponenten, Ethanolgemischen bis zu 85 % (V/V) und Rohstoffen ausgeübt wird. Ein dem trockenen Dampfdruck entsprechender Druck (DVPE, en: dry vapour pressure equivalent) wird aus dem Dampfdruck berechnet.
Bei den Bedingungen, die bei der in diesem Dokument beschriebenen Prüfung angewendet werden, handelt es sich um ein Dampf Flüssigkeitsverhältnis von 4 : 1 und eine Prüftemperatur von 37,8 °C.
Das Prüfgerät wird während der Prüfung nicht mit Wasser benetzt, und das beschriebene Verfahren ist daher für Proben sowohl mit als auch ohne sauerstoffhaltige Komponenten geeignet; in der Probe gelöstes Wasser wird nicht berücksichtigt.
Bei diesem Verfahren wird der Partialdruck der in dem Probenteil gelösten Luft während der Dreifach Expansion berechnet. Es ist für Proben mit einem DVPE zwischen 15,7 kPa und 97,6 kPa geeignet; Dampfdrücke außerhalb dieses Bereiches können gemessen werden, die Präzision wurde jedoch nicht ermittelt.
Dieses Dokument ist anwendbar auf Kraftstoffe, die sauerstoffhaltige Verbindungen bis hin zu den in der maßgebenden Richtlinie 85/536/EWG des Rates [6] angegebenen Grenzen enthalten, sowie für Ethanol Kraftstoff Gemische mit einem Ethanolanteil von bis zu 85 % (V/V).
ANMERKUNG Für die Zwecke dieses Dokumentes werden die Bezeichnungen „% (m/m)“ und „% (V/V)“ zur Angabe des Massenanteils bzw. des Volumenanteils verwendet.

Produits pétroliers liquides - Pression de vapeur - Partie 3 : Détermination de la pression de vapeur et de la pression de vapeur sèche équivalente calculée (PVSE) (Méthode triple expansion)
Le présent document spécifie une méthode de détermination de la pression de vapeur exercée dans le vide par des produits pétroliers, des constituants pétroliers, des mélanges contenant de l'éthanol jusqu'à 85 % (V/V) et des bases pétrolières, volatils et de faible viscosité, en utilisant une chambre à volume variable. Il est possible de calculer une pression de vapeur sèche équivalente (PVSE) à partir de la pression de vapeur.
Les conditions mises en œuvre dans l’essai du présent document correspondent à un rapport vapeur sur liquide de 4:1 et une température d’essai de 37,8 °C.
L'équipement n'étant pas en contact avec de l'eau au cours de l'essai, la méthode est par conséquent applicable aux échantillons contenant ou non des composés oxygénés. Il n'est pas tenu compte de l'eau dissoute dans l'échantillon.
Le présent mode opératoire calcule la pression partielle de l'air dissous dans la prise d'essai, durant le processus de triple expansion. Il convient aux échantillons dont la PVSE est comprise entre 13,7 kPa et 98,3 kPa. Les pressions de vapeur en dehors de cette plage peuvent être mesurées mais la fidélité n’a pas été établie.
Le présent document s’applique aux carburants contenant des composés oxygénés dans les limites définies par la Directive du Conseil 85/536/CEE correspondante [6], et aux mélanges de carburant et d'éthanol contenant jusqu'à 85 % (V/V) d'éthanol.
NOTE Pour les besoins du présent document, les termes « % (m/m) » et « % (V/V) » sont utilisés pour représenter, respectivement, les fractions massique et volumique.

This part is based on and developed in parallel with IP 619 [9] and ASTM D6378 [3].
Introduction
Vapour pressure is used as a classification criterion for the safe handling and carriage of petroleum
products, feedstocks and components; it has a relationship to the potential for hydrocarbon emissions,
under uncontrolled conditions, and thus is the subject of environmental scrutiny.
Vapour pressure limitations are often imposed to prevent pump cavitation during transfer operations.
Vapour pressure is one measure of the volatility characteristics of fuels used in many differing types of
engines with large variations in operating temperatures. Fuels having a high vapour pressure can
vaporize too readily in the fuel handling systems, resulting in decreased flow to the engine and possible
stoppage by vapour lock. Conversely, fuels of low vapour pressure vaporize not readily enough,
resulting in difficult starting, slow warm-up and poor acceleration.
1 Scope
This document specifies a method for the determination of the vapour pressure, exerted in vacuo, by
volatile, low viscosity petroleum products, components, ethanol blends up to 85 % (V/V), and
feedstocks using a variable volume chamber. A dry vapour pressure equivalent (DVPE) is calculated
from the vapour pressure.
The conditions used in the test described in this document are a vapour-to-liquid ratio of 4:1 and a test
temperature of 37,8 °C.
The equipment is not wetted with water during the test, and the method described is therefore suitable
for testing samples with or without oxygenates; no account is taken of dissolved water in the sample.
This procedure calculates the partial pressure of the air dissolved in the test portion during the triple
expansion process. It is suitable for samples with a DVPE between 15,7 kPa and 97,6 kPa; vapour
pressures outside this range can be measured but the precision has not been determined.
This document is applicable to fuels containing oxygenated compounds up to the limits stated in the
relevant Council Directive 85/536/EEC [6], and for ethanol-fuel blends up to 85 % (V/V) ethanol.
NOTE For the purposes of this document, the terms “% (m/m)” and “% (V/V)” are used to represent the mass
and volume fractions respectively.
