1978 – 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.
