Test agencies expressed concern about knowing the material and fitting configuration of adapters in advance of testing. One agency suggested adapter material should match the original valve material strength. Agencies agreed small diameter supply lines present no pressure and temperature issues but suggested mandating a one to two second hold at maximum pressure during cycles. Test agencies questioned whether adapters and TPRD plugs are considered part of the test and whether leakage constitutes failure. Components not covered by UN R134 should be tested per ISO 19887-1.
Proposal to amend Annex 3 paragraph 5.1 regarding the CHSS test article. The modification adds supply lines for additional TPRDs through appropriate adaptors to the required test article components, and clarifies that vent lines shall be connected to TPRDs to direct TPRD exhausts in a manner representative of the configuration in the vehicle. The task force identified contradicting language in the regulation regarding supply lines for additional TPRDs and aims to correct this inconsistency.
The agenda includes continuation of supply line discussions, corrections to UN R134/03, clarifications needed in UN R134/03 with responses from test labs, next steps, and scheduling of next meetings.
TFGP-07-08 provides a draft list of recommendations for GRE-94 addressing glare prevention. Recommendations include providing driver instructions for manual override of adaptive driving beam in case of glare; considering dynamic auto-levelling for all vehicles; lowering maximum installation height of headlamps; investigating aiming differences; defining limits on maximum luminous flux and intensity output; improving adaptive driving beam requirements; introducing motorway adaptive driving beam usage; reducing the 2000 lm limit or making cleaning mandatory; considering dimming of beam pattern; introducing adaptive cut-off line; clarifying definitions for cut-off line; improving connection between type approval and inspection; clarifying practical periodic technical inspection aspects; defining remedies for alignment degradation; defining uniform requirements for floor evenness and headlamp aiming devices; improving market surveillance; and improving driver awareness on headlamp cleaning and levelling systems.
Two presentations were delivered to the task force: one on abdominal injury assessment using human body models in frontal sled simulations, examining seatbelt trauma and submarining effects; and another proposing a real-world frontal crash assessment matrix based on field data, advocating for morphed human body models to represent diverse occupant sizes and ages. Continued discussion on priorities and workshop planning were postponed to the next meeting on April 14, 2026.
Proposal to amend UN R13, 13-H, 79, 89, 130, 131, 139, 140, 152, 155, 156, 157, 171, 175, and 178 by introducing provisions on software identification and software updates. Amendments add new paragraphs referring to Software Identification Number definitions in Consolidated Resolution R.E.3, require manufacturers to provide Technical Services with information on hardware and software influencing performance, permit vehicle manufacturers to apply for new approvals differentiating software versions for registered versus new vehicles while avoiding test duplication, and modify production discontinuation provisions to exclude cases where manufacturers seek approval extensions for software updates of registered vehicles.
