11 Jul 2016 2016-07-12 21:48:42 UTC 3 3 04 series of amendments | Supplement 10 Based upon the adopted proposal: WP.29/2015/94

Text prepared by the UN R44 Technical Services Group to clarify the regulation, including test failure parameters, CRS displacement or locking systems, seat installation color coding systems, and use of load limiting devices. The test procedure would be modified, including an increase in the applied load to exceed the maximum allowed resistance to permit sliding of the strap through the quick adjuster and through rigid parts, increased tolerances related thereto, deletion of the option for shorter shift (deemed unnecessary since it is a test on the strap, not on the complete component), and modification of drawings to improve consistency with the text.

Proposal to limit the use of a booster cushion (booster seat without backrest) with children of a stature greater than 125 cm (i.e., prohibit use of booster cushion for children under 125 cm) and the application for type approval of such CRS only in mass Group III for children of mass from 22 kg to 36 kg and to clarify that a guide strap which constrains the shoulder strap of the adult seat belt in a position to suit the child in a child restraint system cannot be approved as a separate CRS under UN R44.

UN R44 | Revision 3 | Amendment 5 (2017)
26 Jul 2017 2017-07-31 13:41:04 UTC 3 5 04 series of amendments | Supplement 12 Based upon the adopted proposal: WP.29/2016/101

Proposal to amend the toxicity and flammability declarations via references to EN 71 (European safety standards), taking into account procedures of FMVSS 302. The amendments propose the burning rate values of FMVSS 302 (302.4 inches/102 mm per minute), to harmonize the three proposals with regard to EN standards references, and to incorporate the amendment 1 to EN 71-3 (A1:2014).

The proposal also would align requirements for deceleration test devices with acceleration ones (making explicit that it is mandatory to match the corridor for each test) and to add dummy criteria and compliance with ISO 17025 to the information required in test reports.

Proposal to amend UN R44 in line with the proposal to amend UN R14 in order to separate child restraint provisions (including ISOFIX anchorage provisions) into a new UN Regulation. The ISOFIX amendment to UN R14 has been introduced to facilitate the establishment of the International Whole Vehicle Type Approval (IWVTA) regulation by limiting the scope of UN R14 to adult safety belts.
