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
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.

4 Materials
Table 1 lists material groups and materials, which are used in supply systems for liquid fuels. In the case
of the material groups in Table 1 an evaluation of the literature has shown that the resistance against
biogenic and alternative fuels and their blends may be limited.
The material groups steel, stainless steel and cast iron were not considered here as no limitation of
resistance is known for these materials.

Three categories are specified for liquid fuels:
Category A Liquid fuels derived from petroleum refining processes with a maximum viscosity of
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

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.
