In early 2008, the ILCE (Inter-Laboratory Correlation Exercise) was performed by the Korea Particle Measurement Program (KPMP) with a domestic diesel passenger vehicle equipped with a catalyzed DPF between three certification laboratories and the research center of an automotive manufacturer to meet EURO 5 and EURO 6 of particle number concentration for light-duty vehicles. This paper focused on measuring the particle number and mass levels from a representative light-duty diesel passenger vehicle during new European driving cycle (NEDC) mode to analyze the repeatability and reproducibility between laboratories in Korea. In addition, particle size distribution characteristics from ILCE test vehicle were compared with LPG, gasoline, and non-DPF diesel vehicles. From the ILCE test results in Korea, the mean total particle number concentration levels ranged from 5.43E+10 #/㎞ to 1.58E+11 #/㎞ and 0.0003 g/㎞ to 0.0036 g/㎞ for particle mass. Repeatability between participating laboratories ranged from 32% to 66% for particle number, 11% to 70% for particle mass; the reproducibility level was 46% for particle number, and 66% for particle mass emission.
