78. The GRPE ambassador to the IWG on IWVTA and DETA introduced GRPE-87-20 and GRPE-87-21 updating GRPE on the latest information from the IWG on DETA about the implementation of the Unique Identifier (UI) in UN Regulations pertinent to GRPE. He also informed that the budget expected for 2023 to develop the UI had not been approved.

79. The representative from EUROMOT requested more time to review the need for UI in UN Regulations Nos. 96 and 120. He added that initial thinking done assumed that UI would not be able to mandate additional information. He requested to have a second look at the topic if UI could be accompanied with additional information to be read on the component, which would be needed for most engines to be fitted on non-road mobile machineries.

80. The representative from CITA showed a few examples of the impact of UI on space savings, to highlight the fact that in some cases, it would not save much space, and that this would not compensate time spent to search for the information on-line that would otherwise be readily available. He invited to re-think the configuration of UI, with the funding to develop it now being on-hold. The representative from OICA confirmed space was an issue on powertrain and also noted that several UIs could be combined.

81. The GRPE ambassador to the IWG on IWVTA and DETA agreed UI noted there might be advantages to OEMs to save space and a disadvantage to PTI and Type Approval Authorities to quickly get access to information. He proposed to convey to the IWG on DETA and IWVTA that GRPE thought that the disadvantages of UI outweighed their advantages. The representative from CITA believed embedded UI could be of use and again invited to further scrutinize the UI implementation for an optimum implementation for all parties.

82. The representative from the European Commission invited by the ambassador to change “smoke coefficient” by “absorption coefficient” in the remarks of Table for UN Regulation No. 24 in GRPE-87-21.

83. The Chair concluded that further remarks can be sent to the GRPE ambassador.
