Document presents technical challenges to defining retrofit kit types for electric conversion and approval processes. Identifies that retrofit kit type perimeter depends on the regulation considered, with different requirements across UN R10, R13, R100, R85, R138, WLTP, R79, R39, R51, R89, R121, and R122. Presents testing challenges at vehicle, component, and EPRS levels, noting that testing a kit type not installed on a vehicle is impossible to account for all impacts on the vehicle.

Minutes of the twelfth meeting of the IWG on EV/HFCV Retrofit Systems held 28 September 2026. The group adopted the provisional agenda and reviewed the work program, aiming to provide GRPE with a first draft of a future UN Regulation by 14–16 October 2026. The group focused on revising definitions in the draft UN Regulation, particularly EPRS definition, EPRS type, vehicle family, and installer provisions. Key unresolved issues include which components must remain identical within an approved type, alternative ways of grouping vehicles within a family, whether installer requirements should be included in the UN Regulation, and the scope regarding vehicles subject to UN Regulations Nos. 155 and 156.

Draft agenda for the 7th meeting of Task Force 4 Frontal Impact & Restraint System Requirements, scheduled for 21 October 2026. The meeting will cover welcome and agenda approval, approval of previous meeting minutes, progress dashboard review, priority table alignment, preparation for a Japan Workshop in Tokyo in November 2026 including definition of robustness and workshop agenda, conclusions and next steps, and other business.

GRSP sought WP.29 guidance on an apparent contradiction between transitional provisions 15.1.2. and 15.1.3. in the 06 series of amendments to UN R22 (helmets) and article 12.4 of Revision 3 of the 1958 Agreement. WP.29 agreed that the provisions of the 1958 Agreement should prevail over those of specific UN Regulations and that these transitional provisions are invalid, even though the 06 series entered into force on 3 January 2021 after Revision 3 of the 1958 Agreement entered into force on 14 September 2017. Article 12.4 applies to all UN Regulations regardless of date of issuance and preserves each Contracting Party’s freedom to choose whether to accept type approvals issued pursuant to earlier versions.

The meeting will review progress on the dashboard, finalize the HBM board with lower extremities remaining, prepare the board for the TF-4 workshop, and discuss next steps.

The informal working group on Equitable Occupant Protection reviewed the status of five task forces addressing rear-end impact, virtual crash testing, frontal impact and restraint systems, and assessment of currently not considered injury types with high frequency and risk of permanent medical impairment. The group discussed robustness assessment for occupant protection, defined as the vehicle’s ability to protect occupants with variation of body height, weight, shape, physical constitution, and age in real-world relevant collisions. An upcoming workshop in Tokyo will develop conceptual ideas for assessing robustness by evaluating performance over a matrix of human and crash-condition variability, complementing current requirement-specific assessments based on anthropomorphic test devices, with status reports due December 2026 and final report December 2027.

Draft minutes of the 12th meeting of the UNECE GRSP IWG Equitable Occupant Protection Task Force 2 Rear-end impact held online on 28 September 2026. The group discussed Euro NCAP workshop findings on EvaRID seat performance criteria, including preliminary testing results showing higher NIC values and differences in dummy response compared to BioRID. Topics included preventing sub-optimization when introducing new assessment tools, the role of dynamic testing in regulatory requirements, head-restraint adjustment mechanisms, and virtual testing potential for rear impact assessment. The group identified virtual testing validation and near-term practical improvements as priorities for continued consideration.

Input for agenda item 6 concerning definition and discussion on indirect plus and direct systems for CLIV-22. All references to indirect plus or direct sensing systems have been replaced by a CLIV warning system. Definitions for indirect plus or direct sensing would no longer be needed. A proposed CLIV warning system definition is presented for review, with a CLEPA proposal to modify the definition to include assessing if a child is left in a vehicle and triggering warning signals.

Proposal to establish a new UN Regulation to help prevent children being left unattended in M2 and M3, class B and III vehicles designed specifically for the carriage of children. The regulation covers vehicles intended for child carriage and establishes minimum requirements for vehicle-based warning systems. These systems remind drivers or responsible persons to physically inspect the passenger compartment before leaving the vehicle. External visual warnings use direction indicator lamps; audible warnings use type-approved horns or reverse alarm devices, or must pass specified test procedures.

Proposal to define CLIV System as the ability to derive the potential presence of a subject or object inside the car based on logic using sensing information such as pressure or capacitive sensing. CLIV System encompasses indirect sensing methods using door logic alone or door logic combined with additional sensors, indirect sensing without door logic using pressure, capacitive, temperature, motion sensors or CO₂ concentration sensor, and direct sensing using camera, millimeter wave radar, UWB radar, or WiFi sensing to detect the absolute presence of a human inside the vehicle.
