OICA proposal to provide a clearer and more precise definition for “stable acceleration”. The definition introduced in document GRB/2017/02 is specified as "when the acceleration from line AA’ to PP’ has a low variation to the acceleration from line PP’ to BB’.” The term “low variation” is imprecise and so OICA proposes the wording “when the acceleration ratio a_{(PP’-BB’)}/a_{(AA’-BB’)} is lower than 1,2.”

GRB | Session 65 | 15-17 Feb 2017

12. On behalf of the Informal Working Group (IWG) on Additional Sound Emission Provisions (ASEP), the expert from France introduced proposals for Supplement 2 to the 03 series of amendments to Regulation No. 51 (ECE/TRANS/WP.29/GRB/2017/2, GRB-65-25 and GRB-65-26). GRB adopted these proposals, as laid down in Annex III, and requested the secretariat to submit them to WP.29 and AC.1 for consideration and vote at their June 2017 sessions as a draft Supplement 2 to the 03 series of amendments to Regulation No. 51.
