33. The expert from France on behalf of the IWG on CRS, introduced ECE/TRANS/WP.29/GRSP/2015/32 on limiting the use of booster cushions (booster seat without backrest) for children of a stature over 125 cm and on the application for type approval of these CRS only in mass Group III for children from 22 kg to 36 kg. The expert from Sweden introduced a possible alternative symbol (GRSP-58-27), to better clarify the use of this type of CRS for consumers. GRSP adopted ECE/TRANS/WP.29/GRSP/2015/32, as amended by Annex II to this report and requested the secretariat to submit the proposal for consideration and vote at the June 2016 sessions of WP.29 and AC.1 as draft Supplement 11 to the 04 series of amendments to UN Regulation No. 44.

34. The expert from the Russian Federation introduced ECE/TRANS/WP.29/GRSP/2015/33 on excluding the possibility of approval for child restraint systems with a guide strap. GRSP adopted the proposal, as amended by Annex II to this report and requested the secretariat to submit the proposal for consideration and vote at the June 2016 sessions of WP.29 and AC.1 as part of (see para. 33 above) draft Supplement 11 to the 04 series of amendments to UN Regulation No. 44.

35. The expert from CI introduced a presentation (GRSP-58-10) on a proposal (GRSP-58-09) to withdraw ISOFIX CRS from the UN Regulation. He added that the introduction of UN Regulation No. 129 should lead to the discontinuation in production of ISOFIX CRS according to UN Regulation No. 44 because of a lower level of protection offered (i.e. absence of side impact protection). The expert from Germany argued that deleting ISOFIX provisions from the UN Regulation was useless and that this could be simply dealt with in transitional provisions, beyond which date, type approval would no longer be granted to ISOFIX CRS. He added that, at the same time extensions of existing type approvals would be guaranteed in the future. GRSP agreed to resume consideration of a revised proposal at its May 2016 session.

36. The expert from CLEPA introduced a presentation (GRSP-58-25) to clarify the content of a proposal (GRSP-58-16 superseding ECE/TRANS/WP.29/GRSP/2015/6) aimed at introducing new provisions on toxicity and flammability of CRS materials. The experts from Denmark and Sweden had proposed GRSP-58-23 to introduce the flammability test procedure applied in FMVSS 302, which was commonly used throughout the industry. The experts from Denmark, Sweden and CLEPA jointly then prepared GRSP-58-16-Rev.1. Following the request of a study reservation from the experts of France, Germany and Japan. GRSP agreed to resume consideration on this proposal at its May 2016 session. The secretariat was requested to distribute GRSP-58-16-Rev.1 with an official symbol at the next session of GRSP.
