适用范围：This International Standard specifies a test method for the measurement of exhaust gas opacity from compression-ignition (diesel-)engined vehicles. It describes the measurement of exhaust opacity under quasi-steady conditions during a lug-down at full load ?ver the normal operating speed range of the engine.NOTE — This method is most suitable as an inspection station test. The test method with a steady single speed specified in ISO 7645 is also well suited to an inspection station test, but may be used on the road.
