Division 5 RegenerationF1

In the case that a regeneration event occurs during or immediately preceding the procedure set out in point 4, upon completion of that procedure the test may be voided at the request of the manufacturer, irrespective of the cause of the regeneration. In this case the test shall be repeated. The same torque and speed points shall be used although the running order may be changed.

1. (a)

   The engine shall be operated in a manner to ensure that the regeneration event has completed and, where applicable, the soot load in the particulate after-treatment system has been re-established;

2. (b)

   The engine warm-up procedure shall be performed in accordance with point 7.8.1.1 of Annex VI;

3. (c)

   The test procedure specified in point 4 shall be repeated commencing at the stage referred to in point 4(b).
