Proposal for amendments to Regulation No. 54
Document GRRF-78-12
10 September 2014

Clarifications and corrections to document GRRF/2014/26 which proposes to alter the marking requirements of UN R54 to replace the PSI Index by the inflation pressure in kilopascals (“kPa”) and to add the possibility to put the “LT” marking as a prefix or suffix to align the requirements with current practice for C2 tyres with metric size designation.

38. The expert from ETRTO also introduced ECE/TRANS/WP.29/GRRF/2015/27 as amended by GRRF-80-10 proposing to replace the “PSI index” by the pressure in “kPa”. The proposal received several comments e.g. on paragraph 3.1.10. and the use of “may” or “shall”. GRRF agreed to resume consideration of this proposal at its next session on the basis of a revised proposal that the expert from ETRTO volunteered to prepare.
