39、 EMISSION DURABILITY REQUIREMENTS This appendix shall apply to power bands H to K only. 1. Emission durability period and deterioration factors 1.1. Manufacturers shall determine a Deterioration Factor (DF) value for each regulated pollutant for all power band H to K engine families. Such DFs shall
40、be used for type approval and production line testing by either: (a) adding the DF to the emission test result, if paragraph 1.2.1. applies, or (b) multiplying the emission test result with the DF, if paragraph 1.2.2. applies.

41、reemailing clients of the SABS.E/ECE/324 E/ECE/TRANS/505 Rev.1/Add.95/Rev.1/Amend.1 Regulation No. 96 page 6 1.1.1. Test to establish DFs shall be conducted as follows: 1.1.1.1. The manufacturer shall conduct durability tests to accumulate engine operating hours according to a test schedule that is
42、selected on the basis of good engineering judgement to be representative of in-use engine operation in respect to characterizing emission performance deterioration. The durability test period should typically represent the equivalent of at least one quarter of the emission durability period (EDP). S
43、ervice accumulation operating hours may be acquired through running engines on a dynamometer test bed or from actual in-field machine operation. Accelerated durability tests can be applied whereby the service accumulation test schedule is performed at a higher load factor than typically experienced
44、in the field. The acceleration factor relating the number of engine durability test hours to the equivalent number of EDP hours shall be determined by the engine manufacturer based on good engineering judgement. During the period of the durability test, no emission sensitive components can be servic
45、ed or replaced other than to the routine service schedule recommended by the manufacturer. The test engine, subsystems, or components to be used to determine exhaust emission DFs for an engine family, or for engine families of equivalent emission control system technology, shall be selected by the e
46、ngine manufacturer on the basis of good engineering judgement. The criterion is that the test engine should represent the emission deterioration characteristic of the engine families that will apply the resulting DF values for certification approval. Engines of different bore and stroke, different c
47、onfiguration, different air management systems, different fuel systems can be considered as equivalent in respect to emissions deterioration characteristics if there is a reasonable technical basis for such determination. DF values from another manufacturer can be applied if there is a reasonable ba
48、sis for considering technology equivalence with respect to emissions deterioration, and evidence that the tests have been carried according to the specified requirements. Emissions testing will be performed according to the procedures defined in this Regulation for the test engine after initial run-
49、in but before any service accumulation, and at the completion of the durability. Emission tests can also be performed at intervals during the service accumulation test period, and applied in determining the deterioration trend. 1.1.1.2. The service accumulation tests or the emissions tests performed to determine deterioration shall not be witnessed by the approval authority.
