F1 Inserted by Commission Regulation (EU) 2016/1718 of 20 September 2016 amending Regulation (EU) No 582/2011 with respect to emissions from heavy-duty vehicles as regards the provisions on testing by means of portable emission measurement systems (PEMS) and the procedure for the testing of the durability of replacement pollution control devices (Text with EEA relevance).

Sequence for thermal ageing U.K.

Note: The sequence of the modes 1 to 11 has been arranged by ascending load in order to maximise the temperature of the exhaust gas in the high load modes. With the agreement of the type-approval authority, this order can be modified in order to optimise the temperature of the exhaust gas if this can help in reducing the actual aging time.] U.K.
