Software identification and updates for vehicles no longer in production. UN R156 series 01 introduces mandatory RXSWIN for software updates after registration. RE3 Annex 7, UN R157, UN R171, and UN R185 define type approval rules post-production. Manufacturers may apply for new approvals to differentiate software for registered vehicles from new vehicles, covering type approval regulation updates or hardware changes. Duplication of tests shall be avoided where possible. National Type dates need not be respected for new approvals under the 1958 Agreement.
Proposal to amend the Guidelines on Transitional Provisions by applying footnote 6 to V.3 as well as V.8, replacing the added as well language in footnotes 4 to 6 with used instead of, deleting also from footnotes 4 and 5, adding Notwithstanding paragraph V.4 before Contracting Parties applying in footnotes 4 and 5, and using continue to only for the V.8 case in footnote 6 to align terminology, clarify scope, and remove overlaps between main text and footnote wording.
Provisional agenda for the 52nd session of the IWVTA Informal Group scheduled for November 12, 2026 in Paris. The session will address election of a new Chair, adoption of the agenda and 51st session report, highlights from the 199th WP.29 session, amendments to UN R0 series, contradiction between transitional provisions in UN R22 and Revision 3 of the 1958 Agreement, proposed amendments to Guidelines on Transitional Provisions, IWVTA awareness and promotion, extension of mandates, and DETA scheme implementation.
Proposal from the EDO task force on “unlocking” to amend the working draft for the 05 series (EDO-Intermediate-03-02).
The DDADWS 10th (October 2026) session discussed proposals to:
A study of methods to evaluate submarining using human body models and anthropomorphic test devices. The research tested 600 simulations across six environments with one human body model and three anthropomorphic test devices, integrating 20 different indicator definitions. A distance-based nearest node dynamic indicator emerged as most promising. The indicator is purely kinematic, time-resolved, automated, and configurable, depending only on node coordinates without force or sensor outputs. It was subsequently tested and extended to additional anthropometries. The indicator detects submarining effectively and can be combined with complementary criteria.
Document presents results from an open text poll and ranking polls conducted during the EqOP-Japan workshop on robustness assessment. Participants submitted ideas for robustness assessment addressing human body model evaluation, injury types, protection principles, and regulatory framework considerations. Topics ranked include brain injuries, submarining, lower extremities, chest injuries, soft tissue neck injuries, abdominal injuries, and assessment parameters such as lower test speeds, more anthropometries, rear row assessment, and seat position variations.
Study on axonal injury from uniaxial stretching in rat nerve cells. Experiments measured formation of axonal swellings and bulbs following stretching at various strain and strain rate conditions. Results show axonal injury observed at strain levels of 0.18 and above. Under 0.15 strain, injury percentage significantly increased at strain rates over 50 s⁻¹. Under 0.20 strain, injury percentage significantly increased at strain rates over 30 s⁻¹. Injury tolerance for axonal injury assessment should be determined based on combination of strain and strain rate.
Proposal to introduce provisions for triangular retro-reflectors of Class IIIB.
