The US safety agency raises questions concerning the specific nature of the observed failures and the scope of the test procedures to ensure that glazing with ceramic printed areas resist such failures. NHTSA notes anomalies in the data that might suggest failure modes specific to particular manufacturers and/or production batches while questioning the focus on panoramic sunroofs rather than all glazing where ceramic printing might be a potential cause of failure.

Explanatory statement on CPA limitation from Korea.

Proposal from the UN R55 informal group to allow the fitment of a secondary coupling and/or a brake away cable for un-braked O1 trailers or inertia braked trailers up to 3.5t which are equipped with class B coupling heads and class S drawbar eyes (38 mm, 40 mm, and others) and for the related use of integrated towing brackets.

Proposal by the informal working group on Regulation No. 55 concerning vehicle combination applications to introduce:
(a) An amendment for the separation of requirement calculation procedures from the procedure of setting and certifying performance values.
(b) An amendment that adds procedures for requirement calculation for vehicle combinations that have hitherto not been accounted for in the Regulation.

Proposal by the informal working group on Regulation No. 55 and introduces a procedure to identify allowable combinations of performance values DC and V for drawbar coupling equipment.

Proposal by the informal working group on Regulation No. 55 to introduce:
a) Correction of an error in Annex 5, figures 12 and 17;
b) An amendment that concerns identification of worst cases for design assessment;
c) Clarifications on minimum articulation angles.

Proposal to restrict component type-approval for mechanical coupling devices dedicated to category M1 vehicles to use only on such M1 vehicles as are designed to tow trailers.

At its fifty-ninth session, GRSP approved a proposal for the 07 series of amendments to UN R16 to mandate safety belt reminders for all vehicle seats. This proposal aligns provisions in UN R121 with the changes to UN R16:
a) the term “seat belt” is replaced by “safety belt”,
b) the symbol for safety belt, defined in item 21 of Table 1 in the Regulation, may be displayed in different colours to convey different meanings. Therefore, the existing footnote ¹⁸ has been added to item 21, and
c) this symbol may be replaced by different symbols for seats other than those of the front row. Therefore, a new footnote ²² is added to item 21. This proposal does not change any of the technical requirements of UN R121.

Proposal to allow for the approval of speedometers and odometers that enable drivers to display figures either in km/h or mph (but not both simultaneously). The proposal also clarifies the application of the provisions across the category L vehicle subcategories.

Proposal for new safety provisions with regard to LPG systems having hydraulic interconnections with the petrol or diesel fueling system through which inter-flows of fuels may occur.

Proposal to expand the scope of the regulation by deleting paragraph 1.2.2. which allows for the exclusion of “vehicles designed and constructed for special purposes where it is not possible, for practical reasons, to fit lateral protection devices” from the text. The proposal allows Type Approval Authorities to nonetheless exempt “vehicles where any LPD (e.g. fixed, removable, foldable, adjustable, etc.) is incompatible with their on-road use” through the addition of new paragraphs.

Proposal to align the requirements for plastic panes other than windscreens with the requirements of plastic pane windscreens. This includes amendments concerning rigid plastic panes, flexible plastic panes and rigid plastic multiple-glazed units. The proposed modifications to this type of glazing are in line with the requirements of Supplement 4 to the 01 series of amendment of UN Regulation No. 43.

Proposal to improve and clarify provisions concerning the approval of interior materials, cables and insulation materials. The proposaladds new requirements for cable sleeves and conduits, modifies vertical testing requirements under Annex 8 to allow testing of small test samples and to clarify their fixation to the specimen holder., and adds a new Annex 10 on provisions for testing of electrical cables.

Proposal to reduce the administrative burden in obtaining approvals for electrical cables according to UN Regulation No. 118. The experts from Finland, France and Germany agreed that the change from ISO 6722:2006 to ISO 6722-2011 does not impact the degree of safety and, therefore, the test reports or approvals established under the older version of the ISO standard shall remain valid.
