Liquid petroleum products - Vapour pressure - Part 3: Determination of vapour pressure and calculated dry vapour pressure equivalent (DVPE) (Triple Expansion Method)
This European Standard 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 standard 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 13,7 kPa and 98,3 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 European Standard, the terms "% (m/m)" and "% (V/V)" are used to represent the mass and volume fractions respectively.
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.
Flüssige Mineralölerzeugnisse - Dampfdruck - Teil 3: Bestimmung des Dampfdruckes und des berechneten dem trockenen Dampfdruck entsprechenden Druckes (DVPE) (Dreifach-Expansionsmethode)
Diese Europäische Norm legt ein Verfahren zur Bestimmung des Dampfdrucks fest, der im Vakuum von flüchtigen, niedrigviskosen Mineralölerzeugnissen, Komponenten, Ethanol-Blends bis zu 85 % (V/V) und Einsatzprodukten ausgeübt wird, unter Verwendung einer Kammer mit veränderlichem Volumen. Ein dem trockenen Dampfdruck entsprechender Druck (en: dry vapour pressure equivalent, DVPE) wird aus dem Dampfdruck berechnet.
Die in der in dieser Norm beschriebenen Prüfung verwendeten Bedingungen sind 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 der Prüfmenge gelösten Luft während der dreifachen Expansion berechnet. Es ist für Proben mit einem DVPE zwischen 13,7 kPa und 98,3 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 des Rates 85/536/EWG [6] angegebenen Grenzen enthalten, sowie für Ethanol-Kraftstoff-Gemische mit einem Ethanolanteil von bis zu 85 % (V/V).
ANMERKUNG Für die Zwecke dieser Europäischen Norm werden die Bezeichnungen "% (m/m)" und "(V/V)" zur Angabe des Massenanteils bzw. des Volumenanteils verwendet.
WARNUNG - Die Anwendung dieser Norm kann die Anwendung gefährlicher Stoffe, Arbeitsgänge und Geräte mit sich bringen. Diese Norm beansprucht nicht, alle damit verbundenen Sicherheits¬probleme zu behandeln. Es liegt in der Verantwortung des Anwenders dieser Norm, vor ihrer Anwendung geeignete Maßnahmen für die Sicherheit und den Gesundheitsschutz des Personals zu ergreifen, und dafür Sorge zu tragen, dass behördliche und gesetzliche Maßnahmen eingehalten werden.

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 may
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 may not vaporize readily enough,
resulting in difficult starting, slow warm-up and poor acceleration.
1 Scope
This European Standard 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 standard 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 13,7 kPa and 98,3 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 European Standard, the terms “% (m/m)”and “% (V/V)” are used to represent
the mass and volume fractions respectively.
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

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
vapour pressure
VP
total pressure minus the partial pressure of the dissolved air in the liquid at a vapour to liquid ratio of
4:1 and at 37,8 °C
3.2
dry vapour pressure equivalent
DVPE
vapour pressure as calculated via EN 13016-1 by a correlation formula from the measured vapour
pressure (VP)
Note1 to entry: This Part of the European Standard calculates an equivalent DVPE result by applying a
correlation formula. DVPE is only applicable to a vapour to liquid ratio of 4:1 and at a test temperature of 37,8 °C
3.3

3.4
total vapour pressure
TP
pressure exerted in vacuum by air and gas containing petroleum products, components and feedstocks,
and other liquids, in the absence of undissolved water at 37,8 °C
Note 1 to entry: The total vapour pressure reported at the end of the test is at a vapour to liquid ratio of 4:1.
4 Principle
Employing a measuring chamber with a built-in piston, a test portion of known volume is drawn into
the measuring chamber that is temperature controlled at approximately 20 °C. After sealing the
measuring chamber, the temperature of the measuring chamber is increased to the 37,8 °C test
temperature simultaneously with the first expansion using the piston. Two further expansions are
performed to a final test volume of five times that of the test specimen. After each expansion, the total
vapour pressure is measured. The PPA from
