Español1978 – 2014 Japan and the world
| 1978 | Okouchi prize and award of the Directorate General of Japan‘s Research and Development Agency for the development of FFU synthetic wood |
| 1979 | Deming prize for high level and comprehensive quality control |
| 1980 | Field trials of FFU railway sleepers at the bridge over the Miomonte river and in the Kanmon tunnel |
| 1985 | Examination of test sleepers by Japan‘s Railway Technical Research Institute (RTRI). Results are outstanding. FFU synthetic wood is adopted as the standard sleeper by Japanese National Railways (JNR). |
| 1996 | Japan‘s Railway Technical Research Institute (RTRI) retests sleepers from the field trials of 1980. An extrapolation over 100 million load cycles leads to a forecast lifespan of 50 years. |
| 2007 | Japanese industry standard JIS E 1203 is published |
| 2011 | RTRI tests sleepers from field trials of 1980. Results confirm a 50-year life expectancy. Written notification to JNR that sleepers can be used reliably for a further 20 years. |
| 2014 | ISO 12856-1 “Plastic railway sleepers“ in force |
2004 - 2016 Europe
