Proposal to add new CRS fixtures and otherwise align UN R16 with changes introduced through UN R129 (enhanced child restraint systems). Two “Booster Seat” fixtures (ISO/B2 and ISO/B3) were added to UN R16 to coincide with the implementation of Phase 2 of UN R129. 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. The proposal also corrects figure 2 in Annex 1B to show the referenced zones A and B, to add the 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 makes editorial improvements.
