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 total pressure, exerted in vacuo, by volatile, low viscosity petroleum products, components, and feedstocks containing air, including oxygenated fuels containing up to 3,7%mass of oxygen and automotive ethanol (E85) fuel. It uses a three-step wise expansion equipment as an alternative to regular DVPE techniques.
Flüssige Mineralölerzeugnisse - Dampfdruck - Teil 3: Bestimmung des Dampfdruckes und des berechneten Trockendampfdruckes (BTDD) (Dreifache Expansions Methodik)
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.

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
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.

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
partial pressure from dissolved air
PPA
pressure exerted in vacuum from dissolved air that escapes from the liquid phase into the vapour phase
at a vapour to liquid ratio of 4:1 and at 37,8 °C
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 the test portion is calculated from the three resulting
pressures. The vapour pressure of the test portion is calculated by subtracting the PPA from the final
total vapour pressure. The calculated vapour pressure is converted to a dry vapour pressure equivalent
(DVPE) by applying a correlation formula.
NOTE For liquids containing very low levels of high vapour pressure contaminants, which behave like a gas,
this test method that determines the PPA and gases, can lead to wrong results since the partial pressure of the
contaminants will be included in the PPA.

6 Apparatus
6.1 Instrument:
NOTE This European Standard does not give full details of instruments suitable for carrying out this test.
Details on the installation, operation and maintenance of each instrument can be found in the manufacturer’s
manual.
6.1.1 General, apparatus suitable for this test method employs a small volume, cylindrically shaped
measuring chamber with associated equipment to control the chamber temperature at 37,8 °C. The
measuring chamber assembly contains a movable piston to allow sample introduction into the
measuring chamber, and expansion in three predefined volume steps, to a final 4:1 vapour to liquid
ratio. A pressure transducer is incorporated in the piston. The measuring chamber contains an
inlet/outlet valve combination for test portion introduction and expulsion. The piston and the valve
combination are at the same temperature as the measuring chamber to avoid any condensation or
excessive evaporation. The apparatus rinses the measuring chamber with the next sample to be tested,
or a solvent if required.
6.1.2 Measuring chamber assembly, approximately 5 ml total test volume (liquid and vapour) with
a moveable piston to provide a vapour to liquid ratio of 4:1, at the end of the test.
6.1.2.1 The accuracy of this 4:1 vapour to liquid ratio shall be within 3,95:1 and 4,05:1.
6.1.2.2 The volumes used in the calculations for vapour and partial pressures shall be accurate to
within 1 % of the total test volume of the measuring chamber.
6.1.2.3 The chamber shall be capable of retaining a vacuum within 1 kPa for 300 s at the total test
volume position of the piston.
6.1.2.4 The maximum dead volume with the piston at its lowest position shall be less than 1 % of
the total test volume.
The measuring chamber and piston used in generating the precision and DVPE correlation formula
were constructed of nickel plated aluminium, and stainless steel and/or brass respectively with a total
volume of 5 ml. Measuring chambers with different capacities and materials may be used, but the
precision and DVPE correlation formula have not been determined.
6.1.2.5 The test chamber shall be vacuum-tight, with a provision for introducing the sample
The test chamber shall be capable of controlling the temperature of the sample to achieve the specified
test temperature to within ± 0,1 °C.
6.1.2.6 Temperature measuring device, platinum resistance thermometer and electronic
temperature control shall be used to maintain the measuring chamber at 37,8 °C ± 0,1 °C for the
duration of the vapour pressure measurements.
6.1.3 The apparatus shall be capable of measuring the vapour pressure of small samples of petroleum
products, components and feedstocks up to, at least, 200 kPa by means of a pressure transducer.
