This VDA test specification sheet describes the procedure for examining the corrosion of metallicmaterials and surfaces in fuels.Examination results show which material/fuel combinations are most likely to result in corrosivereactions. 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 operationvary 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 agreedbetween the parties involved.It must be noted that the results obtained for different materials cannot be applied to different fuelqualities. The corrosion behavior of a material in gasoline cannot imply its corrosion behavior indiesel. 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 conducttests extending beyond the scope of this preliminary examination, with such testing involving boththe type of exposure prevailing in practice as well as appropriate functional checks.The applicable safety regulations on handling fuels must be followed.
