Draft of the amendments pursuant to the REC informal group session of 19-20 February 2013. The amendment is being developed in parallel to the proposed REC regulation and would introduce a second phase of requirements.

Draft text of the planned ‘phase 2’ amendment to the new regulation on retrofit emissions control devices presently in its final steps towards adoption.

Proposal prepared by the REC expert group for the 01 series of amendments to the UN Regulation on uniform provisions concerning the approval of Retrofit Emission Control devices for heavy-duty vehicles. The text includes a revision in the definitions of the REC devices, stricter limit values (reduction levels) for REC systems and transitional provisions for the sale of REC systems that meet the requirements of the REC Regulation in its original form. To assure coherence with the change in the definitions, the text also includes a revision of the test sequence for particulate reduction and the equivalence matrix for the Regulation No. 49 Standard series.
