29. The expert from Spain introduced GRSP-64-06, GRSP-64-02-Rev.1, GRSP-64-03-Rev.1, GRSP-64-04-Rev.1 and GRSP-64-05-Rev.1 which aimed at providing better provisions for the dummy’s head displacement when surpassing the reference plane DE during frontal and rear impact tests of forward facing Enhanced Child Restraint Systems (ECRS). She explained that these documents were revised proposals and have already been introduced at the May 2018 session of GRSP (ECE/TRANS/WP.29/GRSP/63, para. 33) to provide better rationales for the sled test. GRSP adopted GRSP-64-02-Rev.1, GRSP-64-03-Rev.1, GRSP-64-04-Rev.1 and GRSP-64-05-Rev.1 as reproduced in Annex V to the session report. The secretariat was requested to submit GRSP-64-02-Rev.1 as draft Supplement 9 to the original version of UN Regulation No. 129, GRSP-64-03-Rev.1 as draft Supplement 6 to the 01 series of amendments, GRSP-64-04-Rev.1 as draft Supplement 5 to the 02 series of amendments and GRSP-64-05-Rev.1 as draft Supplement 2 to the 03 series of amendments to UN Regulation No. 129 for consideration and vote at the June 2019 sessions of WP.29 and AC.1.
