| Subject | Comment on Emission Measurement Method |
| Comment | The emission measurement method for diesel PM for demonstrating control efficiencies for alternative control technologies (f)(4)(B)3. should allow CARB Test Method 5 or U.S. EPA Reference Method 5 and 202. The ISO 8178 Test Methods needlessly require a dilution tunnel, 5 stable test modes, and a different temperature (125 F) defining PM. Auxilliary engine exhaust stack diameters and gas velocity are normally within the range to allow standard isokinetic PM sampling. Accepted CARB standard methods should be utilized to provide consistency in PM measurements. |
