57. The Secretary of GRRF reported to the follow-up to the decision of WP.29 at its March 2016 session (ECE/TRANS/WP.29/1120, para. 38): (i) discussion of GRRF in the framework of IWVTA (WP.29-168-15), (ii) the performance of automotive systems (e.g. Tyre Pressure Monitoring Systems) in conditions other than those tested according to the regulated test procedures. He informed GRSP that some safety systems, especially those relying on software, could possibly be designed to only work in limited conditions corresponding to those tested rather than in all the relevant driving conditions. GRSP did not provide any feedback on this subject and agreed to remove the item from the agenda of the next sessions.
