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 at a single speed at full load, and is designed to ensure a correlation with measurement under steady-state conditions.NOTE — This method is most suitable as an inspection station test but the test may also be carried out on the road. The lug-down test specrfied in ISO 7644 is only suited to an inspection station test
