Chairperson presented TR-RUCC-K-04.

Chairperson: we should check current GTR leg components if they pass the original GT corridors.

Bernard Been: all current legs were developed to pass the agreed TEG GTR component corridors. The GT tests and corridors are no longer relevant. If the GTR does not pass the GT corridors, could it mean that all 23 legs need bone replacement? What is the purpose of repeating GT tests? The group should focus on dynamic test corridors.

Chairperson: we expect only a small influence of tests condition change for component level certification tests, but we have not checked this. It is important to review all steps of the certification procedure. For component check (PE sheet to roller carriage comparison) 3 bones would be sufficient.

Bernard Been: bone material is missing in the slides as a variable. Would be good to show in the slides.

Mark Burleigh: we did not see major problems with first Vinyl ester bone batch, problems only showed up with subsequent batches.

Oliver Zander: would be good to show number of tests used to set corridors and number of legs.

Mark Burleigh: asked for further testing to be added to future action plan we should retest due to different bone material, different bone batches and longer rubber flesh. The component review would be needed first.

Oskar Ries: If legs go into regulation we must have reliable corridors that can be met in the future. The group must be confident that the legs are build consistently and reproducible, before it can commit to spending a big effort on a large test matrix. As starting point, we must first establish that the legs going into the round robin meet the current GTR component tests consistently.

Chairperson: Based on our discussion at this meeting, TR-RUCC-K-03 and TR-RUCC-K-04 will be modified (TR-RUCC-K-03-Rev.1 and TR-RUCC-K-04-Rev.1). As for the activity schedule after Jan. 2012, we will discuss again at the 1st TF-RUCC meeting in Jan. 2012.
