Liquid petroleum products - Determination of total contamination - Part 1: Middle distillates and diesel fuels
This European Standard specifies a method for the determination of the content of undissolved substances, referred to as total contamination, in middle distillates, in diesel fuels containing up to 30 % (V/V) fatty acid methyl esters (FAME), and in neat FAME. The working range is from 12 mg/kg to 30 mg/kg and it was established in an interlaboratory study by applying EN ISO 4259 [2].
This European Standard in general applies to products having a kinematic viscosity not exceeding 8 mm2/s at 20 °C, or 5 mm2/s at 40 °C, e.g. diesel fuel as specified in EN 590 [1].
This test method may be used for diesel fuels containing more than 30 % (V/V) FAME and for petroleum products having a kinematic viscosity exceeding 8 mm2/s at 20 °C, or 5 mm2/s at 40 °C, however in such cases the precision of the test method is not defined.
NOTE 1 Excessive contamination in a fuel system can give rise to premature blocking of filters and/or hardware failure, and is therefore undesirable.
NOTE 2 For the purposes of this European Standard, the term "% (V/V)" is used to represent the volume fraction, φ, of a material.
WARNING - Use of this standard may 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 the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.

Der zulässige Messbereich von 12 mg/kg bis 26 mg/kg wurde anhand von Ringversuchen unter Anwendung von EN ISO 4259-1 [1] festgelegt.
Dieses Dokument gilt im Allgemeinen für Erzeugnisse mit einer kinematischen Viskosität nicht über 8 mm2/s bei 20 °C bzw. 5 mm2/s bei 40 °C, z. B. Dieselkraftstoffe nach EN 590 [2].
Dieses Prüfverfahren kann ebenfalls für Dieselkraftstoffe mit mehr als 30 % (V/V) FAME sowie für Mineralölerzeugnisse mit einer kinematischen Viskosität oberhalb von 8 mm2/s bei 20 °C oder 5 mm2/s bei 40 °C eingesetzt werden. Für diese erweiterte Anwendung des Prüfverfahrens gibt es bisher allerdings keine Präzisionsangaben.
ANMERKUNG Für die Zwecke dieses Dokuments wird zur Angabe des Volumenanteils, φ, einer Substanz der Ausdruck "% (V/V)" verwendet.
WARNUNG - Die Anwendung dieses Prüfverfahrens kann den Einsatz gefährlicher Stoffe, Arbeitsgänge und Geräte mit sich bringen. Dieses Verfahren gibt nicht vor, alle mit seiner Anwendung verbundenen Sicherheitsprobleme anzusprechen. Der Anwender dieses Verfahrens ist dafür verantwortlich, vorher angemessene Maßnahmen hinsichtlich Sicherheit und Gesundheit zu ergreifen und die Anwendbarkeit einschränkender Vorschriften zu ermitteln.

Introduction
Excessive contamination in a fuel system can give rise to premature blocking of filters and/or hardware
failure, and is therefore undesirable. The determination of the content of undissolved substances,
referred to as total contamination, is a way to control this issue.
In the previous version of this method, the scope was covering middle distillates, diesel fuels containing
up to 30 % (V/V) of FAME and neat FAME. It was found that the improvement sought in 2014, give
problems in the lab in testing FAME and correlate the results to those obtained with the previous version
of the method. A solution has been found, which resulted in splitting the methodology in two parts: to
include the previous version as Part 1 and to develop a separate standard for neat FAME as Part 2.
1 Scope
This document specifies a method for the determination of the content of undissolved substances,
referred to as total contamination, in middle distillates, in diesel fuels containing up to 30 % (V/V) fatty
acid methyl esters (FAME). The working range is from 12 mg/kg to 26 mg/kg and it was established in
an interlaboratory study by applying EN ISO 4259-1 [4].
This document in general is applicable to products having a kinematic viscosity not exceeding 8 mm /s
at 20 °C, or 5 mm /s at 40 °C.
This test method can be used for paraffinic diesel fuels as specified in EN 15940, for diesel fuels
containing more than 30 % (V/V) FAME and for petroleum products having a kinematic viscosity
2 2
exceeding 8 mm /s at 20 °C, or 5 mm /s at 40 °C, however in such cases the precision of the test method
has not been determined.
NOTE For the purposes of this document, the term “% (V/V)” is used to represent the volume fraction, φ, of a
material.
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 the user of this document to establish appropriate safety and health practices and
determine the applicability of regulatory limitations prior to use.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminology databases for use in standardization at the following addresses:

3.1
total contamination
undissolved substances retained on a filter after filtration under test conditions
3.2
absolute pressure
pressure measured relative to zero pressure or a total vacuum
4 Principle
A sample portion is weighed and filtered under vacuum through a pre-weighed filter. In the case of liquid
2 2
petroleum products having a kinematic viscosity exceeding 8 mm /s at 20 °C, or 5 mm /s at 40 °C, the
weighed sample portion is diluted with a solvent before filtration. The filter with the residue is washed,
dried and weighed. Contamination is calculated from the difference in mass of the filter and expressed
relative to the sample mass as mg/kg.
5 Reagents and materials
5.1 Heptane, with a purity no less than 99,0 % (V/V), filtered using a membrane filter (6.18).
NOTE Heptane used as a reference fuel in EN ISO 5164 [5] is suitable.
5.2 Propan-2-ol, with a purity no less than 99,0 % (V/V).
NOTE Propan-2-ol is used to dry glassware and the sample container after rinsing with water.
6 Equipment
All glassware and sample containers shall be carefully cleaned as described in Clause 7.
Usual laboratory apparatus and glassware, together with the following:
6.1 Filtration apparatus, suitable for a filter (6.2), as shown in Figure 1.
A different filtration apparatus may be used if it is suitable to take the filters given in 6.2.
6.2 Filters, of high retention glass fibre type, 47 mm in diameter and with a 0,7 μm mean pore size.
NOTE Glass fibre filters Whatman GF-F type have been found suitable for total contamination measurements.
