Excerpts from session reports
GRRF | Session 78 | 16-19 Sep 2014

33. GRRF agreed to defer consideration of ECE/TRANS/WP.29/GRRF/2014/26 and GRRF-78-12 to its February 2015 session.

GRRF | Session 80 | 15-18 Sep 2015

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.
