Document Title Proposal for amendments to document GRRF/2015/27 (Regulation No. 54)
Reference Number GRRF-80-10
Date
14 Sep 2015
Summary Document GRRF/2015/27 proposes to modify the marking requirements to replace PSI with kilopascals (“kPa”). The intent is to harmonize the pressure indication and avoid confusion between UN Regulation No. 54 and US FMVSS 119 or FMVSS 139. This proposal would allow for the use of kPa markings in place of PSI prior to the 1 January 2018 transition date.

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.
