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.
