Introduction
Both the limited range and scope of crude oil and other fossil energy sources, as well as the impact on
the climate resulting from the anthropogenic output of greenhouse gases, have led to a politically
induced initiation of the restructuring of energy usage.
In addition to increasing actual efficiency in the technical utilization of fossil energy sources, the focus is
on the development and expansion of renewable energies. The integration of regenerative resources in
sustainable heat generation can reduce the output of greenhouse gases such as CO , as well as the need
2
for fossil energy sources. As a bio-component of blends, fatty acid methyl ester (FAME) is currently
used. As a result of the chemical/physical properties, as well as evaporation and combustion
characteristics, experience shows that an admixture is possible up to 30 % (V/V) FAME [22, 23]. Due to
the possible interactions of the blends with components and in particular with non-ferrous metals such
as copper/brass, the manufacturers of consuming units and devices have approved their products only
to a limited extent for such an admixture. By contrast, the manufacturers of tanks and components in
the fuel piping consider their products to also be suitable for blends with higher admixtures.
However, with regard to the increasing market penetration of blends as a liquid fuel with biogenic or
alternative admixtures, requirements for the materials used should be defined and stipulated as
standard. There is, therefore, the need to prove the resistance of the materials used against these fuels.

1 Scope
This Technical Report includes application-relevant metallic materials of supply systems for liquid fuels
and their blends with regard to corrosive or service life reducing influences. Assessment of the
specialist literature showed possible interactions with biogenic and alternative fuels and motor fuels as
well as their blends with mineral oil and motor fuels. The results of this assessment are given in this
CEN/TR.

5 Liquid fuels
Three categories are specified for liquid fuels:
Category A Liquid fuels derived from petroleum refining processes with a maximum viscosity of
2
10 mm /s at 20 °C, e.g. fuel category ISO-F-D according to ISO 8216-99.
NOTE 1 Liquid fuels derived from petroleum refining processes are listed in CEN/TR 15738.
Category B Liquid fuels from renewable resources, e.g. FAME according to EN 14214 or alternative
fuels.
Category C Mixtures of category A and B, e.g. diesel as a motor fuel according to EN 590, EN 15940,
EN 16709.
NOTE 2 For national requirements for liquid fuels, see Annex A.
6 Resistance of metallic materials to liquid biogenic and alternative fuels and
their blends
Statements from the literature on the resistance of the material groups against biogenic and alternative
fuels and their blends are collated in Table 2.
The test methods or test conditions of the published specialist literature references are only rarely
described with precision. Therefore, an own evaluation of the resistance of the various different
material groups against biogenic and alternative fuels and their blends was effected in Table 2.

In connection with the literature research relevant reports by the “Deutsche Wissenschaftliche
Gesellschaft für Erdöl, Erdgas und Kohle (DGMK)” (German Scientific Association for Mineral Oil,
Natural Gas and Coal) were taken into account. In some reports on specific topics there are no details to
be found with regard to material compatibility [31, 32, 34]. The few statements contained therein with
regard to the material compatibility of metals do not allow for any classification according to the
scheme of Table 2, since none of their own examinations were carried out; there are only quotations
from various different specialist literature references, that are shown in Table 2 [29, 30, 33].
7 Test procedure on resistance
The closely connected standards ASTM G1 and ASTM G31/NACE TM-01-69 specify an immersion test
for evaluating the corrosion of materials when in contact with various different liquid media. With
regard to test conditions, no parameters are specified. Instead it is pointed out that the test conditions
should be orientated in accordance with the respective purpose of the test, so that it is possible to
achieve the highest possible approximation to the actual practical use of the respective material. The
composition of the test media as well as the test temperatures and durations are thus to be selected
freely and as close as possible to actual practice.
The steel pin corrosion test is a currently used procedure for the evaluation of mineral oils and other
liquids with regard to the corrosion of parts made of iron in the presence of water. In accordance with
the standard ISO 7120 this immersion test is used
