Periodical Technical Inspections: Minutes of the 43rd (May 2026) session

The 43rd session of the IWG on PTI convened on 8 May 2026 in Brussels. The group reaffirmed the need to strengthen integration between type approval and in-use inspection per WP.29 Whole-Life Compliance framework (WP.29/2023/89). At least 20 UN Regulations contain incomplete, non-harmonised PTI provisions. The IWG agreed to add “Review of PTI provisions in UN Regulations (1958 Agreement)” to its Action Plan and submit a proposal to WP.29 requesting endorsement. Work on diagnostic tools in PTI and automated vehicles inspection continues. The group reviewed recent amendments to UN Regulations Nos. 13 and 13-H for new braking technologies and identified challenges regarding LED replacement light source inspection.

Excerpts from session reports
GRE | Session 89 | 24-27 Oct 2023

6. GRE noted that a revised concept on vehicle whole-life compliance that had been prepared by the Informal Working Group on Periodical Technical Inspections (IWG PTI) (ECE/TRANS/WP.29/2023/89) would be considered at the November 2023 session of WP.29.

WP.29 | Session 191 | 13-16 Nov 2023

132. The Chair of the IWG on PTI introduced ECE/TRANS/WP.29/2023/89, a proposal for a Framework Document on Vehicle Whole-Life Compliance, aimed at providing guidance to WP.29 and its GRs to coordinate the evaluation of harmonised conditions for the assessment of performances of vehicles, equipment and parts along different stages of their legal life.

133. The representative of Sweden raised her concerns with regards to:


(i) Compliance, related to PTI provisions added to UN Regulations and the follow up process,
(ii) The impact of this framework document on the relation between manufacturers and the inspections bodies as well as on the possibility for inspection bodies to act independently.

134. The Chair of the IWG on PTI clarified that this document was intended to be a reference document for the methodologies of drafting rules that would be applied by all GRs and IWGs when preparing relevant proposals, and that it would not propose a change in the work of the technical authorities. The representative of the Netherlands supported this clarification and highlighted the possibility to modify the document in the future.

135. The representative of Sweden agreed that this document could be adopted since it was not binding and understood as a living document. She stressed that more work and discussions need to take place before it could be implemented.

136. WP.29 endorsed the document as a reference document and agreed to keep it as a living document.
