Brussels
Agenda Item 6.8.
Cumulative acceleration (3ms) presentation by TASS

show and explain difference between γ(3ms) cumulatively & γ(3ms) continually.

According to Farid BENDJELLAL (BRITAX) , it’s not clear in the current R129 regulation.

It’s different in the R44 regulation because it’s defines 3ms “exceedance”. For Tommy PETTERSSON (VTI), we do not have to change the current R44 regulation. Pierre CASTAING (UTAC & chairman) agree to make modification for γ(3ms) cumulatively for phase I in chapter 8.1 and Annex 17. Erik SALTERS (DOREL): we can add something like “Align R129 to R44 by improving definition of R129.
