Materials and adhesives used in the construction of vehicle interiors can emit volatile organic compounds(VOCs), aldehydes, or other substances that are harmful to human body. Korea, Japan, and China have legislation related to this subject and ISO 12219-1:2012 concerns the measurement of volatile organic compounds in cabin interiors. Many vehicle manufacturers have also addressed this issue. Therefore, Korea proposes that WP.29 undertake an effort to establish worldwide uniform standards to ensure healthy vehicle interior air quality (VIAQ).

Proposal for an informal expert group to exchange information and develop recommendations concerning vehicle interior air quality as it relates to emissions of volatile organic compounds or aldehydes from materials used in vehicle interior which are harmful to humans. The proposal envisions the development of test procedures to measure such emissions for incorporation as recommendations within the Consolidated Resolution on the Construction of Vehicles (RE3 under the 1958 Agreement), Special Resolution 1 (SR1 under the 1998 Agreement), or as a new Mutual Resolution (covering both agreements).

Korean study of the exhaust emission level and engine control characteristics during EURO-VI Vehicle use a combination of EGR System & exhaust after treatment devices (LNT, SCR etc.). Comparison of test methods between NEDC, WLTP and RDE modes.

Proposal by the USA, European Union, Japan and the Republic of Korea to request revision of the authorization to develop a future proof global technical regulation of Real Driving Emissions based on Phase 2 work by the RDE informal working group.

Proposal to pursue development of methods for life cycle assessment (LCA) as an overall assessment from production to use and disposal as a means to substantially reduce CO2 emissions.

Proposal to clarify the intent of “a means of detecting that the driver is holding the steering control” by specifying that the vehicle manufacturer would define “holding the steering control” (e.g., one hand, two hands, firmness of grip, etc.) for each vehicle/system under test.

Proposal from Germany and the Republic of Korea to resolve measurement concerns in the test requirements for ACSF of Category B1 and C. The proposal addresses issues identified in Annex 8, improves reproducibility and robustness of the procedures, fills in gaps in the test cases, and provides additional details on measuring equipment and test execution.

Proposal to introduce technical requirements for Corrective Steering Functions (lane departure prevention, lane-keeping assistance (LKAS), steering angle correction, etc.) as defined in the regulation. The proposal offers four options to ensure appropriate approvals of LKAS and related CSF systems until such time as more precise requirements can be defined:

• Option 1 and option 2: Not to grant any type approvals for corrective steering functions until detailed technical requirements for CSF are incorporated into this Regulation.
• Option 3: Amend the definition of CSF as proposed in this document.
• Option 4: Amend the definition of corrective steering functions and to include technical requirements for LKAS as an ASCF of Category B1 as proposed in this document.

Proposal to amend the methodology of the 227g ball drop test for toughened glass in order to assess its mechanical strength (resistance against outside impact). This proposal stems from Korean testing that demonstrated inadequate mechanical strength of toughened glass treated with ceramic printing.

Proposal to amend the test methods for toughened glass pursuant to Korean defect investigations involving the ceramic printed area of certain panoramic sunroofs.

Proposal to add a new symbol (as defined by IEC standard 60417-5009) for power on/off controls in electrified vehicles (e.g., electric or fuel cell vehicles).

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

Proposal to modify the draft Amendment 2 to GTR 6 regarding obscuration area definitions.

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

Proposal to introduce a new definition for “radiant warmer”, to exclude such devices from the definition of “electric heater”, and to add a new safety requirement that such warmers must turn off immediately if there is contact with a vehicle occupant’s skin.

Proposal to align UN R43 with provisions in GTR 6 concerning the exemption of possible opaque obscuration areas from Zone I of the test area on the windscreen of M₂, M₃ and N categories of vehicles. This proposal updates and supersedes document GRSG/2023/7.

Proposal to amend the draft text to introduce provisions for radiant warmers into the regulation.

Proposal to clarify the vehicle conditions of the test methods for detection systems in Annex 10, including to specify that not only rear hatches or trunk lids but also the tail gates of cargo trucks and van-type vehicles should be closed or latched in their normal vehicle operating condition during the test.

Revised proposal intended to supersede the text proposed in GRSG/2024/4 (proposal to clarify that indicators, their identifications and identifications of controls need not be illuminated under certain conditions).

Republic of Korea proposed that indicators, their identifications, and the identifications of controls do not need to be illuminated if the driver intentionally deactivates the illumination and the electric vehicle is not in driving conditions. (ECE/TRANS/WP.29/GRSG/2024/4)

Proposal for the positioning of escape hatches for vehicles of classes I, II and III

Proposal to amend the supplement 5 to the Original Version of UN Regulation No. 158 and this proposal corrects the contents of the working document (ECE/TRANS/WP.29/GRSG/2024/4) and combines the informal document(GRSG-128-14)

Proposal for consolidating similar subfunction controls (e.g., climate
control) into a unified system enables easier selection and contributes to
reducing distraction while driving.

PSG informal group proposal to correct the scope of the GTR in accordance with Part A of the GTR, its UN R43 counterpart, and corresponding regional/national interpretations and to align the impact test procedure description with that of UN R43 and ISO 3537.

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

Proposes to clarify that the indicators, their identifications and the identifications of controls need not be illuminated, when it is bright enough outside of the vehicle, such as when daytime running lamps are operated.

Proposal to align UN R43 with provisions in GTR 6 concerning the exemption of possible opaque obscuration areas from Zone I of the test area on the windscreen of M₂, M₃ and N categories of vehicles.

Proposal to align UN R122 to technological progress concerning the use of radiation warmers in electric vehicles. The radiation warmer is expected to increase energy efficiency of EV and is also able to prevent the sharp reduction of All Electric Range (AER).
