                  (a) Decide that the in-service conformity testing of an engine system family is satisfactory and not take any further action;
                  (b) Decide that the data provided is insufficient to reach a decision and request additional information and test data from the manufacturer;
                  (c) Decide that the in-service conformity of an engine system family is unsatisfactory and proceed to the measures referred to in paragraph 9.3. of this Regulation and in paragraph 9. of this annex.
8.  Confirmatory vehicle testing
              8.1. Confirmatory testing is done for the purpose of confirmation of the in-service emission functionality of an engine family.
              8.2. Approval authorities may conduct confirmatory testing.
              8.3. The confirmatory test shall be performed as vehicle testing as specified in paragraphs 2.1. and 2.2. Representative vehicles shall be selected and used under normal conditions and be tested according to the procedures defined in this annex.
              8.4. A test result may be regarded as non-satisfactory when, from tests of two or more vehicles representing the same engine family, for any regulated pollutant component, the limit value as determined according to paragraph 6. is exceeded significantly.
9.  Plan of remedial measures
              9.1. The manufacturer shall submit a report to the Type Approval Authority where the engines or vehicles subject to remedial action are registered or used when planning to conduct remedial action, and shall submit this report when deciding to take action. The report shall specify the details of the remedial action and describe the engine families to be included in the action. The manufacturer shall report regularly to the Type Approval Authority after the start of the remedial action.
              9.2. The manufacturer shall provide a copy of all communications related to the plan of remedial measures, and shall maintain a record of the recall campaign, and supply regular status reports to the Type Approval Authority.
