The agenda includes adoption of meeting minutes from the 5th EDO Meeting and two intermediate sessions, documents for WP.29’s 200th session requesting authorization to amend UN GTR No. 1 and 14, transformation to IWG with Terms of Reference and Rules of Procedure, amendments to UN Regulation No. 11 and No. 21, discussion of open items, and preparation of working documents for GRSP’s 80th session.

This document addresses terminology inconsistencies in UN R11 regarding emergency door opening. It proposes consistent use of entry or exit and occupant(s) versus passenger(s) in amendments without editorial changes to existing parts. Step-by-step checks of all parts of UN R11 are proposed for locking device terminology and latch release control terminology, with definitions for latch release control and door handle already available. For power supply terminology, a definition is needed, while power loss terminology should be retained.

Proposal to insert new paragraphs in Section I defining the background, scope, and technical rationale for emergency door opening provisions addressing power loss scenarios, insert new paragraphs 3.25. to 3.31. in Section II defining terms including “latch release control”, “door handle”, “retractable door handle”, “unlock”, “unlatch”, and “power loss”, insert new para. 4.3. establishing requirements for exterior and interior door operation with intuitively accessible latch release controls and door handles on doors providing direct occupant access, insert new para. 5.4. specifying that latch release controls and door handles shall be intuitive, that power-assisted latch release controls shall remain capable of unlatching doors after power loss for at least 60 minutes through secondary mechanical means, active secondary power supply, or fail-safe systems, that power-assisted latch release and unlocking controls shall similarly remain functional after 60 minutes of power loss, that power-assisted door opening systems shall remain manually openable after power loss, that door handles including retractable door handles shall provide accessible gripping features to unlatched doors after power loss, and that unlocking means and latch release controls shall be unobstructed, directly visible, and not located in storage devices or obstructed by interior components, and insert new Annex 6 specifying test procedures for interior and exterior door operation after power loss, including vehicle preparation steps, 60-minute waiting periods, and opening procedures to be completed within 10 minutes with up to five cycles per door.

Proposal to amend UN R11 to modify scope and definitions regarding vehicles of categories M₁ and N₁, introduce provisions for Automated Driving Systems, revise door operation requirements including exterior and interior latch release controls and door handles, add performance requirements for power-assisted systems and intuitive operation, amend provisions on door locks for side rear doors and back doors, include new definitions for latch release control, door handle, retractable door handle, unlock, unlatch, door opening, and power loss, add transitional provisions for the 05 series of amendments, and introduce new test procedures in Annex 7 for power loss events with interior and exterior door opening procedures requiring demonstration of door functionality within 60 minutes of power disconnection and at least five opening cycles. The amendments apply to supplement 3 of the 04 series for vehicles of category X and the 05 series of amendments to UN R11, based on justifications in GRSP-79-19 and GRSP-78-48.

The document addresses open issues and comments regarding UN R11 and GTR No. 1 concerning emergency door opening. It proposes defining vehicle master control switch as the device bringing onboard electronics from off to normal operation mode, and suggests activating this switch rather than switching ignition on in test procedures. The document defines main power supply as power source(s) and supply path(s) normally used for door system operation, excluding secondary or back-up supply. It raises concerns about secondary or back-up power supply failure occurring in the field before emergencies despite compliant test results. The document discusses objective intuitiveness criteria including visibility, accessibility, discoverability, identification, and operability. It recommends standardized marking for exterior door handles and proposes that door opening and closing procedures be described in vehicle owners’ manuals.

Proposal to amend para. 1.1. to clarify that the Regulation applies to vehicles of categories M₁ and N₁ with respect to latches, door retention components, latch release controls, and door handles to prevent the risk of occupants being thrown from a vehicle and to ensure evacuation at emergency events, insert new paras. 2.30. to 2.36. defining latch release control, door handle, retractable door handle, unlock, unlatch, door opening, and power loss, insert new para. 5.4. establishing exterior and interior door operation requirements, insert new para. 6.4. establishing requirements for latch release controls and door handles to be intuitive and to remain capable of operating after power loss for at least 60 minutes, and insert new Annex 7 establishing a power loss test procedure to verify door opening systems remain functional following an emergency event leading to loss of the vehicle’s ordinary power supply.

This document presents draft provisions for UN Regulation No. 11 concerning door latches and door retention components. Inspired by justifications in GRSP-79-19 and GRSP-78-48, amendments address vehicles equipped with Automated Driving System features (ADSF-1 and ADSF-2), extending requirements to vehicles of category X while excluding category Y. Key EDO additions include definitions for latch release controls, door handles, power loss, and unlock/unlatch operations. New performance requirements mandate intuitive latch release controls and door handles; power-assisted exterior and interior controls must remain functional for at least 60 minutes after power loss through secondary mechanical means, active secondary power supplies, or fail-safe principles. Annex 7 introduces a power loss test procedure verifying door operability following emergency events, with interior and exterior opening procedures conducted within 10 minutes after 60-minute power disconnection periods.

Proposal to establish a submergence test procedure requiring that at least one window per row of seats be capable of being fully opened after a vehicle enters water for occupant escape, with the window operable up to 2 minutes after submergence as designed by the manufacturer, defining container dimensions to accommodate the vehicle without wall or floor contact during the 2-minute period except when fully submerged, permitting open-water test sites provided they comply with test conditions while prohibiting freshwater lakes, reservoirs, and saltwater bodies, requiring the master control switch position allow window operation, specifying unladen kerb mass with measuring apparatus not changing axle reference load by more than 5 per cent, lowering the vehicle into water-filled container at horizontal angle 0–10 degrees with time zero defined as when lowering straps become slack and vehicle floats freely, requiring the vehicle remain in water for 2 minutes from time zero without floor contact until fully submerged, requiring window operation by remote system after 2 minutes with vehicle immersed, and permitting alternative subsystem tests demonstrating window opening functionality under submerged conditions.

Proposals developed during the EDO session to:

• Amend para. 1.1. to include application to evacuation of occupants in emergency events,
• amend definitions of child safety lock system, full locking system, and door closure warning system,
• insert new definitions of latch release control, door handle, retractable door handle, unlock, unlatch, power loss, vehicle master control switch, main power supply, and door opening,
• insert new para. 5.4. establishing requirements for exterior and interior door operation including latch release controls and door handles,
• amend para. 6.3.1. to reference exterior latch release control and insert para. 6.3.1.1. requiring full locking systems to activate only when vehicle master control switch is deactivated with specified measures,
• amend para. 6.3.2. for side rear doors,
• insert new para. 6.4. establishing requirements for intuitive operation of latch release controls and door handles, power-assisted systems capability after 60-minute power loss, and unobstructed positioning,
• insert new para. 7.3. requiring testing in accordance with Annex 7,
• insert new Annex 7 establishing power loss test procedures for interior and exterior door opening after main power supply disconnection.

Discussions to amend GTR 1 to require doors providing direct access for occupants to be equipped with an intuitively accessible exterior latch release control or alternatively in close vicinity to the door. The document notes that “intuitive,” “discoverable,” and “in close vicinity” are subjective terms difficult to assess objectively. It suggests defining these terms through objective criteria such as untrained first-time user performance testing within a specified timeframe, standardized ISO symbols, defined proximity zones relative to the door, and requirements balancing accessibility against inadvertent operation risks.

Working draft proposal to:

• Amend paragraph 1.1. to include application to evacuation of occupants in emergency event
• Amend the definition of child safety lock system in paragraph 2.7.1. to specify prevention of unlatching when interior latch release control is activated and describe normal locked/unlocked logic when inactive,
• Amend the definition of full locking system in paragraph 2.7.2. to refer to interior latch release control,
• Amend the definition of door closure warning system in paragraph 2.9. to replace ignition with master control switch,
• Insert new paragraphs 2.30. to 2.38. defining latch release control, door handle, retractable door handle, unlock, unlatch, power loss, vehicle master control switch, main power supply, and door opening,
• Insert new paragraph 5.4. establishing requirements for exterior and interior door operation including latch release controls, door handles, and unlocking means,
• Amend paragraphs 6.3.1. to 6.3.2. to address exterior and interior locking devices and full locking systems with reference to master control switch deactivation and alarm or acoustic warning provisions,
• Insert new paragraph 6.4. prescribing intuitive operation of latch release controls and door handles, requirements for power-assisted systems to function after power loss for 60 minutes, and door handle design for opening after power loss,
• Insert new paragraph 7.3. requiring testing of power-assisted latch release controls and door opening systems in accordance with Annex 7,
• Insert new Annex 7 establishing a power loss test procedure to verify door opening functionality from interior and exterior following main power supply disconnection, with 60-minute wait before testing and door opening completion required within 80 minutes after power disconnection based on GRSP-78-20/Rev.1 and GRSP-78-48.

Proposal to renumber paragraph 5.8.4.2. as paragraph 5.8.4.3., insert new paragraph 5.8.4.2. requiring controls of electric side windows adjacent to the front seat row to be within reach and directly accessible, insert new paragraphs 5.8.8. and 5.8.8.1. to 5.8.8.2. requiring electric side windows of the front seat row to function for at least 2 minutes during vehicle submergence, and insert new Annex 11 prescribing submergence test procedures including container-based test, slope-entry test, and alternative test methods to demonstrate window opening capability under water.
