26. Recalling the discussion on UN Regulation No. 121 at its previous session, GRSG agreed to remove ECE/TRANS/WP.29/GRSG/2010/20 from the agenda. GRSG considered generic provisions for symbols of automatic systems and agreed on ECE/TRANS/WP.29/GRSG/2012/11. The expert from OICA introduced GRSG-102-22 superseding ECE/TRANS/WP.29/GRSG/2011/32 and proposing to extend symbol Nos. 25 and 28 to the logics of the ISO colour coding and its hierarchy of alerts to the danger. GRSG adopted both documents, as reproduced in Annex VIII to this report, and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2012 sessions, as draft Supplement 8 to UN Regulation No. 121.
