Proposal to establish a Task Force on Swappable Batteries (TFSB) under GRPE. The task force will review WP.29 regulations and international standards to identify technical requirements for swappable-battery vehicles, focusing on commercial vehicles. It will define vehicle types, clarify vehicle type approval processes, and develop guidance documents. The task force will coordinate with other working groups including GRSP and GRVA, with deliverables expected by October 2027.
Proposal to establish a UN Global Technical Regulation for measuring brake particulate matter and particle number emissions from heavy-duty vehicles. The regulation defines laboratory test procedures using a brake dynamometer and the Worldwide Harmonized Heavy-Duty Vehicles Brake Cycle (WHBC), encompassing 20,353 seconds with 246 brake events across three driving segments. Tests require brake bedding with six WHBC repetitions, followed by emissions measurement. Laboratories must measure PM10 and PM2.5 mass gravimetrically and total and solid particle numbers (TPN10, SPN10) using particle counters. Technical specifications cover brake enclosure design, sampling tunnel configuration, climatic control, instrumentation calibration, and data reporting requirements to ensure reproducible and comparable brake emissions testing across regions.
Seven UN Regulation proposals were reviewed for consistency and errors. Issues identified include: unclear optical-logical signal transitions in R64; redundant definitions that should reference RE3 via footnotes; inconsistent ADS activity terminology requiring standardization to “when an ADS feature is active”; incorrect Category Y vehicle references in R51; spelling and numbering errors across multiple regulations; inconsistent Mass in Running Order definitions; and unclear testing provisions requiring improved cross-referencing. Corrections are necessary for regulatory robustness.
Proposal from the GRE EMC informal working group. The modifications extend the regulation’s scope to vehicles without driver compartments or manual controls. Changes include new definitions for ADS test configurations, updated immunity-related functions to address ADS sensor performance, and revised test conditions for vehicles with active ADS features. Additional reporting requirements for ADS systems are introduced in regulatory forms.
This document specifies testing procedures to verify door-opening systems remain functional after complete power loss. Interior testing requires unlocking, unlatching, and opening doors from inside the vehicle five times after a 60-minute wait following power disconnection. Exterior testing requires unlocking, unlatching, and opening doors from outside five times under identical conditions. All operations use only permanently installed components without tools.

Proposal to exempt metallic and glass elements because they are not affected by the tests according R118.
