is unsatisfactory and proceed to have confirmatory testing carried out on a sample of engines from the engine family, according to section 5 of this Annex.

             3.5. A Member State may conduct and report its' surveillance testing, based on the audit procedure spelled out in this section. Information on the procurement, maintenance, and manufacturer's participation in the activities may be recorded. Likewise, the Member State may use alternative emission test protocols, according to section 3.1.11.5, item (h).

             3.6. The type-approval authority may take up surveillance testing conducted and reported by a Member State as a basis for the decisions according to section 3.4.

             3.7. The manufacturer should report to the type-approval authority and the Member State(s) where the subject engines/vehicles are kept in service when planning to conduct a voluntary remedial action. The reporting shall be supplied by the manufacturer in conjunction with taking the deci- sion to take action, specifying the particulars of the action, describe the groups of engines/vehicles to be included in the action, and regularly thereafter on the commencement of the campaign. The applicable particulars of section 7 to this Annex may be used.

         4.        EMISSION TESTS

             4.1. An engine selected from the engine family shall be tested over the ESC and ETC test cycles for gaseous and particulate emissions and over the ELR test cycle for smoke emission. The engine shall be representative of the type of use expected for this type of engine, and come from a vehicle in normal use. The procurement, inspection, and restorative maintenance of the engine/vehicle shall be conducted using a protocol such as is specified in section 3, and shall be documented.

              The appropriate maintenance schedule, referred to in section 4 of Annex II, shall have been carried out on the engine.

             4.2. The emission values determined from the ESC, ETC and ELR tests shall be expressed to the same number of decimal places as the limit value for that pollutant, as shown in the tables in section 6.2.1 of Annex I to Directive 2005/55/EC, plus one additional decimal place.

         5.        CONFIRMATORY TESTING

             5.1. Confirmatory testing is done for the purpose of confirmation of the in-service emission functionality of an engine family.

             5.1.1. If the type-approval authority is not satisfied with the manufacturers' ISM according to section 3.4 or on a reported evidence of unsatisfactory in-service conformity, e.g., according to section 3.5, may order the manufacturer to run test for confirmatory purposes. The type-approval authority will examine the confirmatory test report supplied by the manufacturer.

             5.1.2. The type-approval authority may conduct confirmatory testing.

             5.2. The confirmatory test should be applicable engine ESC, ETC and ELR tests, as specified in Section 4. Representative engines to be tested should be dismounted
