Guidance document for approval authorities on using DETA to implement UN Regulation No. 155. Notifying authorities shall upload cyber security information as PDF files no later than 14 days before granting a first-time approval, complete mandatory fields including approval number and date, and send a notification message to other authorities via DETA. Other approval authorities may submit comments within 14 days of notification by email and DETA message. Notifying authorities shall upload received comments to DETA without undue delay. These procedures apply before first-time approvals and each time assessment methods or criteria are updated.

Report on the secure internet database DETA for exchanging approval documentation between Contracting Parties of the 1958 Agreement. DETA has 41 notified Focal Points, approximately 153,300 approvals uploaded by 23 TAA, and approximately 8,700 manufacturers available. Migration to new software version with enhanced features including two-factor authentication, mailing functions, adaptations for UN R155/171/157 guidelines, and additional languages is planned for Q1/27. The IWG on DETA highlights DETA as an open, neutral, trustful platform for authorities to exchange compliance documents and invites input on new use cases.

The 57th session of the Informal Working Group on DETA will be held on Friday 13 November 2026, 9:30-12:30 (CET), as a hybrid meeting at the OICA office in Paris. The provisional agenda includes approval of DETA-57-01e rev1, approval of draft minutes DETA-57-02e, state of play, new DETA software version, widening DETA’s scope, potential use for sharing technical information regarding proposed GRPE UN Regulation on brake emission of non-original parts, adding an attribute to indicate latest series of amendments of approvals, potential update of the IWG’s Terms of Reference (ECE/TRANS/WP.29/2008/117) per DETA-54-03e-rev1, initial draft amending Guidelines for use of DETA regarding Cyber Security exchange due to new DETA software version per DETA-57-03e, report to WP.29 per DETA-57-04e, and next meetings.

In GRPE, discussions regarding control of aftermarket brake components with regard to brake particle emissions have prompted CLEPA’s desire to have access to type approval information to enable development of these components. Vehicle manufacturers make considerable investment in deriving these data and a supplier typically does not offer all affected brake components making a simple compliance test more difficult. OICA and CLEPA members are coming closer to an agreement regarding the necessary data, reducing the amount of data to be shared. A similar situation has been identified between UN R13H and UN R90.

The IWG on DETA held its 56th session on 18 June 2026. The group approved previous session minutes and noted 132,000 approvals uploaded by 23 approval authorities. A new DETA software version with two-factor-authentication, email features, and French and Spanish language options is being tested. The IWG agreed to change DETA’s meaning from “Database for the Exchange of Type Approval Documentation” to “Data Exchange for Transport Authorities”. The group discussed potential DETA use for sharing technical information on brake emissions and updating its Terms of Reference. An attribute to indicate the latest series of amendments for approvals was proposed for future consideration.

The 56th meeting of the Informal Working Group on DETA is scheduled for 18 June 2026, 9:30-12:30 (CET), as a hybrid meeting at KBA office in Flensburg, Germany. The agenda includes approval of provisional agenda and draft minutes from the 55th session, state of play, new DETA software version, widening DETA’s scope including results from a 17 June DETA/IWVTA Joint Workshop and considerations on renaming DETA, potential use of DETA for sharing technical information regarding proposed GRPE UN Regulation on brake emission of non-original parts, potential update of IWG’s Terms of Reference, guidance on data exchange via DETA in context of UNR157 on ALKS, and adding an attribute in DETA to indicate latest series of amendments of approvals.

The IWG on DETA discussed system operations showing 118,000 uploaded approvals with 41 contracting parties accessing the platform. Topics included widening scope to non-1958 Agreement parties, potential regulation updates for brake emission parts, renaming DETA to reflect broader applications, guidance on data exchange for ADS vehicles, adding attributes for series compliance, and granting read-only access to candidate countries. A June workshop will promote IWVTA and DETA adoption.
