Download in .pdf format Download in .docx format

Proposal

  • to clarify the requirements for the type approval of booster seats in the over 135 cm category,
  • to update a reference with the new European Committee for Standardization (CEN) published EN 71-3:2019 on 10 April 2019,
  • to delete a cut-and-paste error in Annex 6, Appendix 2 taken from UN R44 referring to ECRS as in the “restricted” category which does not exist in UN R129,
  • to reconcile and consolidate various references to tolerances for the internal geometry assessment, and
  • to exclude the head acceleration criterion in certain cases of contact when testing booster cushions with the larger Q-dummies, in particular the Q10, due to dummy rebound over the back of the test bench during a frontal test.
