UN R124: Proposal for Supplement 2

Document WP.29/2021/9

17 December 2020

183rd WP.29 session (9-11 Mar 2021)

Proposal to align the acceptance criterion listed in the table in Annex 8, paragraph 3, with the negative rating criterion listed in paragraph 5 (c): total loss of inflation pressure within one minute. This change clarifies that only a complete decrease in the pressure in the tyre due to its depressurization is a negative evaluation criterion when conducting an impact test.

Status: Adopted
