21. The expert from CI introduced ECE/TRANS/WP.29/GRSP/2017/20 to definitively phase out approvals granted to non-integral group 2 or group 2/3 of child restraint systems (CRS). The expert from CLEPA supported a unique set of provisions in the future (UN Regulation No. 129) to which the CRS manufacturers could refer. However, he introduced the rationales in GRSP-62-18 for an adequate time period to implement this transition sensibly. In response to the presentation of CLEPA the expert from CI stated that the timeline of the withdrawal of group 0, 0+ and 1 integral harness from UN Regulation No. 44 should not precedent the withdrawal of group 2/3 CRS. He explained that a short lead time could apply, as demonstrated by CRS manufacturers in the past and could allow consumers to benefit from a higher standard as soon as possible. However, the expert from France noted that the transitional provisions proposed by ECE/TRANS/WP.29/GRSP/2017/20 cannot be applied from the administrative point of view and proposed a one year delay to cease new type approvals. The expert from the United Kingdom encouraged a compromise to allow the industry to phase out any such provisions from UN Regulation No. 44. Finally, GRSP agreed on the transitional provisions set out GRSP-62-29 and adopted ECE/TRANS/WP.29/GRSP/2017/20 as amended by Annex VI to this report. The secretariat was requested to submit it to the June 2018 sessions of WP.29 and AC.1 as draft Supplement 14 to the 04 series of amendments to UN Regulation No. 44.
