26. The expert from Germany introduced informal document GRSP-76-07 to correct the values given in UN Regulation No. 127 for the moments of inertia of the femur and the tibia of the flexible lower legform impactor. This would bring UN Regulation No. 127 in line with UN GTR No. 9 Phase 2 and M.R.1 addendum 3, where these values had already been corrected. GRSP supported the amendments but indicated a preference for incorporating them as supplements to the relevant series of amendments rather than as corrigenda. The expert from Germany proposed to come back to the next session with a working document.
