Derailing tests
The impact test intended to simulate derailing was carried out using a shock load of a 500 kg mass dropped from a height.
After two tests at the same spot, FFU synthetic wood showed merely the image of a "wheel flange". Even after this derailment simulation the FFU sleeper remained dimensionally stable; this guarantees that the track gauge is maintained if a derailment occurs.
Test at low temperature
To analyse their behaviour at low temperatures, FFU sleepers were put into storage at -20°C.
The ensuing test showed that, even at extremely low temperatures, FFU retains its technical properties and the fibres of FFU synthetic wood remain free of brittleness.
