UN R24: Proposal for a Supplement
Document GRPE-85-23
30 December 2021

The use of test fuels is permitted for certification testing of gaseous and particulate pollutants and power/smoke testing in Europe. However, other countries that have adopted and referenced UN R24 may not allow this. This proposal would permit the use of the same test fuel in cases where the testing for emission of gaseous and particulate pollutants is conducted at the same time as the testing under UN R24.

40. The representative from OICA introduced ECE/TRANS/WP.29/GRPE/2022/22 and ECE/TRANS/WP.29/GRPE/2022/23 on reference fuels allowed to be used when performing tests according to UN Regulations Nos. 24 and 85. The representative from the UK found the proposals acceptable and would be willing to adopt after removal of the square brackets. The representative from the European Commission required proposals to be bundled so regulatory texts are not updated at every GRPE session, that increases the administrative burden and might be perceived as bad legislative development. The representative from Italy stated he would be willing to adopt the proposals in this session to facilitate adoption and certification processes around the globe. The representative from the European Commission suggested to only adopt ECE/TRANS/WP.29/GRPE/2022/22 in this session and to bundle all proposals to amend UN Regulation No. 85 at forthcoming sessions of GRPE, including ECE/TRANS/WP.29/GRPE/2022/23. GRPE agreed with this approach.

41. GRPE adopted ECE/TRANS/WP.29/GRPE/2022/22 as amended during the session and reflected in Annex VII to the session report and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their November 2022 sessions as draft new supplement to the 03 series of amendments to UN Regulation No. 24 (Visible pollutants, measurement of power of C.I. engines (Diesel smoke)).

38. The representative from OICA introduced GRPE-85-23 and GRPE-85-24 proposing to widen test fuel specifications to local requirement in UN Regulations Nos. 24 and 85. The representative from the UK suggested the wording of the proposed amendment could be clarified. GRPE agreed to consider a revised proposal at forthcoming session of GRPE.
