Timeline

1978 – 2014 Japan and the world

1978Okouchi prize and award of the Directorate General of Japan‘s Research and Development Agency for the development of FFU synthetic wood
1979Deming prize for high level and comprehensive quality control
1980Field trials of FFU railway sleepers at the bridge over the Miomonte river and in the Kanmon tunnel
1985Examination 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).
1996Japan‘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.
2007Japanese industry standard JIS E 1203 is published
2011RTRI 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.
2014ISO 12856-1 “Plastic railway sleepers“ in force
