A Konosu/chairperson presented TF-RUCC-1-04 to introduce Japan observations as well as Japan proposals. Proposal was to re-examine all the GTR corridors by preparing bones that are in the middle of the bone corridor to avoid going back to discussion on injury thresholds. Japan proposed to carry out this testing at JARI because JARI has the original test rigs which were used to make static and pendulum corridors.

Different results were obtained with bone core between JARI and Humanetics. M Burleigh requested the JARI bone fixture to set up the round robin bones and look to see if it was the fixture or the test set up that was the problem.

JARI propose the use of the PE sheet as opposed to the rollers as it is more stable, repeatable and easier to control.

BASt again opposed that a high repeatability in that context should not alone decide on whether to use the PE sheet test setup because the repeatability is due to unintended friction.

Dr Ries confirmed the importance of a stable consistent build, M Burleigh said this proposed procedure from the bone core up should ensure this.
