RECOMMENDED PRACTICE FOR MEASUREMENT OF EXHAUST SULFATE EMISSION FROM LIGHT-DUTY VEHICLES AND TRUCKS

Various test procedures for the measurement of exhaust sulfate (measured as sulfuric acid) emission from light-duty vehicles and trucks are described. Several test sequences were examined and the conclusion was reached that the sulfuric acid test should follow the exhaust emission measurements in the test sequence. This paper is structured in Federal Register format. This format incorporates sulfuric acid testing for the 1979 and later model years, although this is not to be taken as an indication that a sulfuric acid emission standard will be promulgated for the 1979 model year. Any sections in the current Federal Emission Test Procedure (Subpart B) which are affected by the incorporation of sulfuric acid testing are included in this recommended practice.
