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.
