Proposal to amend para. 2.12. to replace the reference to ISO [CD] 19206-4 with ISO 19206-4:2020 and specify an adult bicyclist target, and amend para. 5.3.2. to replace the reference to ISO [CD] 19206-4:2018 with ISO 19206-4:2020, clarify requirements for demonstrating BSIS performance for smaller bicycles and smaller bicyclists differing by up to 36 per cent from nominal dimensions for the adult bicyclist target through physical testing using a child bicyclist target, simulation sufficiently validated by physical testing, or another documented means sufficiently valid and accurate to establish BSIS performance for a child bicyclist target.

Status report on the Special Interest Group on Component & Separate Technical Unit work on UN R158 and UN R159. The SIG-C&STU is developing proposals to add Component and Separate Technical Unit approval routes to UN R151, UN R158, UN R159, and UN R166. For UN R159, Supplement 4 is under review with documents at GRSG-132. For UN R158, a Proposal for Supplement 7 is in development. The group requests feedback on structural approaches and timelines for working document submissions by January 2027.
