This VDA test specification sheet describes the procedure for examining the corrosion of metallic
materials and surfaces in fuels.
Examination results show which material/fuel combinations are most likely to result in corrosive
reactions. Specific fuels and defined temperature/time profiles are used for this purpose.
If the temperatures and pressures that surfaces contacting fuel are exposed to in real operation
vary significantly from the temperatures and pressures planned for the purpose of examination,
these parameters should also be aligned in testing. In this case, such variations must be agreed
between the parties involved.
It must be noted that the results obtained for different materials cannot be applied to different fuel
qualities. The corrosion behavior of a material in gasoline cannot imply its corrosion behavior in
diesel. This also applies to admixtures of synthetically manufactured or biogenic fuel additives.
The aging behavior of fuels is not taken into consideration.
In reaching the decision to select materials for vehicle components, it is also necessary to conduct
tests extending beyond the scope of this preliminary examination, with such testing involving both
the type of exposure prevailing in practice as well as appropriate functional checks.
The applicable safety regulations on handling fuels must be followed.
