The FAM testing fluid corresponds neither to a motor fuel commercially available at the time this standard was prepared, nor to any motor fuel anticipated for the future. It can be considered as a testing fluid intended to assess the behaviour of polymer materia

It cannot be expected that these circumstances are fully revealed in every case by the ethanol and water content of the FAM testing fluid at test temper- atures and durations normally employed. Thus, in order to avoid long-term tests, the use of other methods of test in- tended to demonstrate this is recommended for polymer materials sensitive in this respect.
