Document Description

WP29 to consider the request from Republic of Korea for authorization to develop an amendment to UN GTR 6 (Safety Glazing)

Document Description

Proposal to exempt Zone I from opaque obscuration requirements of GTR 6 under certain conditions.

Document Description

Proposal to introduce provisions for the optional use of laminated-glass panes with improved mechanical properties, particularly for the front, exterior, forward-facing glazing of the upper deck of a double-deck vehicle.

Document Description

Proposal to:

1. clarify that the application of an AECD approval to other vehicle categories than M₁ and N₁ is not mandatory,
2. align the power supply requirement of Part III, para. 34.1 with the corresponding requirement in Part II, para. 25.1.
3. clarify with regard to para. 34.1 that if the vehicle is equipped with both
   • -a “back-power supply” as listed in para. 35.10.1 and
   • -a “Power supply other than back-up power supply mentioned in paragraph 35.10.1” as listed in para. 35.10.2
   both should be tested according to Annex 9. The “Power supply other than back-up power supply mentioned in paragraph 35.10.1” should indeed only be tested if it is the only power supply for the AECS.
4. include two-year transitional provisions
5. remove the exclusion of M₁ and N₁ not equipped with a side airbag and to specify that the AECS shall be able to output the navigation solution in an NMEA-0183 protocol format (RMC, GGA, VTG, GSA and GSV message), among other clarifications.

Document Description

Proposal to specify that "the motor-vehicle’s user instructions (e.g. owner’s manual, vehicle handbook) shall clearly specify that the removable or repositionable mechanical coupling device shall always be removed or repositioned when it is not in use.” The purpose is to comply with an EU General Safety Regulation provision that prohibits couplings from obscuring rear lighting components or registration plates.

Document Description

Proposal to introduce a generic drawing to improve interpretation of the regulation, especially with regard to contactable parts (sphere protocol). The proposal clarifies which requirements apply to which part of the windscreen wiper and thus clarifies whether parts may be “exempted”. Given the implications for approvals, the proposal is presented as a new series of amendments with transitional provisions starting from September 2022.

Document Description

Proposal to clarify that UN R144 does not specify the frequency (number) of attempts or the duration of efforts to establish a network connection (voice or data transmission) for automatic emergency call systems.

Document Description

Proposal to correct erroneous references (to annexes in the regulation as well as to UN R94 and R95) in the text and to correct an inconsistency in the text (paragraph 26.7.2. refers to situations where the AECS is not equipped with a back-up power supply; however, the subparagraph 26.7.2.3. refers to an AECS with a back-up power supply).

Document Description

Proposal to add a missing footnote concerning the exemptions for heaters located outside the passenger compartment using water as a transfer medium and to clarify that it is not necessary to apply Annex 4 for the heat pump because the heat transfer fluid does not contain polluting air.

Document Description

Proposal to introduce changes/additions in the Change of Design Table to better specify appropriate test requirements for CNG cylinders with composite materials and, in some cases, to harmonize with International Standard Organisation (ISO) standard 11439.

Document Description

Proposal to clarify provisions for periodic testing and periodic requalification of Compressed Natural Gas (CNG) cylinders and Liquefied Natural Gas (LNG) tanks.

Document Description

Proposal to introduce a definition for “Aerodynamic devices” and ensure that such devices shall not compromise the functionality of rear underrun protection devices.

Document Description

Proposal to

1. clarify test procedures allowing non-random selection of parameter combinations and
2. provide for protrusion requirements for Blind Spot Information Systems (BSIS) external elements.

Document Description

Proposal to enable the use of small indicative lines to assist the driver in discriminating among two or more fields of vision rendered as a combined continuous image on a display.

Document Description

Proposal to introduce provisions for activation of a “temporary modified view” (such as change in image magnification or resolution) per ISO 16505:2015 to complement the static Class II field of vision using a Camera Monitoring System (CMS).

Document Description

Proposal to exempt rear edges of fenders and rear edges of A pillars under certain conditions from the requirement that sheet metal edges be folded back or fitted with a shield.

Document Description

For escape hatches on buses of Classes A and B, proposal to allow a maximum length of 1600 mm equally spaced to cover the shortest vehicles, so the allowed space should be the maximum of either the third of the length or 1600 mm. This proposal will not affect the positioning requirements for any mid-sized and larger buses.
