Draft text prepared by the Task Force Bumper Test Area (TF-BTA), a subgroup of the Informal Working Group on gtr No. 9 – Phase 2.

Proposal from the Bumper Test Area Task Force, pursuant to discussions within GRSP, to revise the procedure for determining the bumper test area under the pedestrian safety regulation. This proposal corrects shortcomings in the current definitions which could lead to a narrower test area than intended (leading to less effective pedestrian protection). This proposal does not take into account potentially harmful hard structures such as bumper beams that may lie behind the outer contour or front fascia extending beyond the defined bumper corners as consensus within the task force could not be reached. Presented as a Supplement, the proposal includes a September 2017 transition date in case GRSP determines that the changes should be put into a new series of amendments rather than as a supplement.

Proposal from the Bumper Test Area Task Force, pursuant to discussions within GRSP, submitted as an alternative to the proposal in document GRSP/2014/31 as amended by document GRSP-56-40, to revise the procedure for determining the bumper test area under the pedestrian safety regulation. This proposal corrects shortcomings in the current definitions which could lead to a narrower test area than intended (leading to less effective pedestrian protection). This proposal includes a “bumper beam” determination method. The proposal also includes a September 2017 transition date in the event that the GRSP determines that the proposal should be treated as a new series of amendments rather than as a Supplement.

Notice on the publication of an EC-sponsored study on the benefits and feasibility of a range of new technologies and unregulated measures in the field of motor vehicles and on future plans of the Commission in this regard.

Proposal to amend document GRSG/2015/8 which would revise the procedure for determining the bumper test area under the pedestrian safety regulation.

Proposal by the expert from EC on behalf of the Drafting Task Force to align the UN Regulation with the revised General Safety Regulation of the European Union – appropriate transitional provisions, and minor adaptations and clarifications to the existing requirements. This proposal will allow contracting parties to apply an enlarged head impact zone for regulatory compliance testing.

Proposal to align UN R127 with provisions set out in the revised General Safety Regulation (EU) 2019/2144 that will apply in the European Union in accordance with the proposed transitional provisions. The proposal also covers a specific provision on optional monitoring of headform contact with A-pillars, windscreen header and cowl and proposes inconsequential adaptations and clarifications to the existing requirements

Revised ECE/TRANS/WP.29/GRSP/2021/28

A decision was taken in mid-2025 to start drafting a new regulation for category Y vehicles. TF AVRS agreed to amend UN R127 to include Y-category vehicles. Supplement 5 to the 04 series of amendments proposes: for vehicles of category Y, dimensions based on front structural geometry shall determine exemptions ensuring equivalence to R-point criteria; Bonnet Rear Reference Line is defined for category Y vehicles without a windscreen; Front structure definition includes outer structures and, for category X and Y, automated driving sensors essential for vehicle operation; Normal ride altitude testing shall be at Unladen Vehicle Mass.

UN R127 amendment proposals include defining pedestrian protection requirements for category Y vehicles. Scope exemptions for category Y vehicles shall use front structural geometry to determine exemptions, ensuring equivalence to R-point criteria. Definitions require adjustments including Bonnet Rear Reference Line for vehicles without windscreens, Front structure definition to include automated driving sensors, Windscreen test area redefined as Upper structure test area where windscreens are non-existent, and supporting definitions for Side reference line and Cowl monitoring area. Testing shall occur at Unladen Vehicle Mass.

A decision was taken in mid-2025 to start drafting a new regulation collecting relevant safety requirements for Category Y vehicles. UN R127 on pedestrian safety performance could be directly amended to include Y-category vehicles instead of including requirements in a new regulation. TF AVRS agreed to amend UN R127 to include Y-category vehicles. A draft regulation (v4) is available proposing supplement 5 to the 04 series of amendments, including amendment suggestions in scope to determine exemptions for Y-category vehicles based on front structural geometry dimensions rather than R-point criteria.
