Proposal to update the 07 series of amendments in line with UN R129 and changes to the 06 series (Supplements 8 and 9). Two “Booster Seat” fixtures (ISO/B2 and ISO/B3) were added to UN R16 to coincide with the implementation of Phase 2 of UN Regulation No. 129. These fixtures were developed within ISO/TC 22/SC 36/WG 2 (Child Restraint Systems) and follow the principle already established in Regulations 16 and 129 to ensure child restraint to car compatibility. An additional “Reduced-Size Rearward Facing toddler CRS” fixture (ISO/R2x) was added to facilitate compatibility in small cars/seating positions. The ISO/B2 booster seat fixture was added in the i-Size concept. Lateral facing fixtures (ISO/L1 and ISO/L2) have been upgraded.

This informal doc amends the draft supplement presented in document GRSP/2016/24 in order to harmonize the mass tolerances of the ISO fixtures. The proposal deletes a reference to the center of gravity and geometrical centroid. The centroid would need more information before choosing tolerances needed for certification tests.

Proposal to correct figure 2 in Annex 1B to show the referenced zones A and B, to add sentence “Non-rigid material of < 50 Shore A hardness may be removed in order to demonstrate that covered or padded rigid parts are not contacted by the head or the chest of the manikin during the test.”, and to make editorial improvements.
